Flaxseed gum, also known as Frank gum and sesame gum, is a powdered product made from flax seeds or seed coats through a series of complex extraction, concentration, refining and drying processes.

As a new type of food additive, flaxseed gum has made a great splash in the food industry, and is also gradually emerging in other fields such as the pharmaceutical industry.

In the food industry, it is like a “jack of all trades”, able to replace traditional additives such as pectin, agar, gum arabic, and alginate, and plays multiple roles such as thickener, adhesive, stabilizer, emulsifier and foaming agent, greatly expanding the possibilities of food processing and injecting new vitality into the innovative development of the food industry.

Unique Physical and Chemical Properties

The appearance of flaxseed gum is diverse. The most common ones are yellow granular crystals and white to beige powder. When you sniff it closely, you can also smell the faint sweet fragrance from the dry powder, which gives people a rustic and natural feeling.

In terms of solubility, flaxseed gum has a unique performance. It can slowly absorb water and form a dispersion system with low viscosity. When the concentration is lower than 1-2g/L, it can be completely dissolved.

At this point, its solubility is higher than guar gum and locust bean gum, but it is still slightly inferior to gum arabic.

From the perspective of chemical composition, flaxseed gum is composed of acidic polysaccharides and neutral polysaccharides, among which acidic polysaccharides are dominant, and the molar ratio of acidic polysaccharides to neutral polysaccharides is 2:1. This unique ratio gives flaxseed gum special chemical properties.

Excellent Functionality

Emulsification:

In the emulsification comparison test, flaxseed gum was used as the test group, and gum arabic, seaweed gum, etc. were used as the control group. Different concentration gradient tests were set up.

Flaxseed gum has the best emulsification effect, and the higher the concentration, the stronger the emulsification effect. It is a kind of gum with strong emulsification, which can make fat disperse better and increase the amount of fat meat to make the food fragrant and not greasy.

Gelling:

As a hydrophilic colloid, some hydrophilic colloids (such as gelatin, etc.) can gel by themselves, and some need to be compounded with other colloids. The viscosity of flaxseed gum is affected by many factors.

The viscosity of 1% flaxseed gum ranges from 350 to 2500mpa.s, and the viscosity of undried gum is higher;
The longer the gel is placed, the higher the viscosity, and the higher the temperature, the lower the viscosity;
The viscosity is the highest when the pH is 6-8, and the viscosity will decrease under acidic and alkaline conditions.

This characteristic enables it to help form a stable structure in food and improve the texture.

Foaming property:

It can be dissolved in water in any proportion to form a uniform glue solution. Adding 50% – 60% alcohol will produce flocculent precipitation. A 0.5% glue solution can form a uniform and stable foam after centrifuge separation.

It will not destroy the foam recovery solution until it is heated to 90℃ for half an hour. Good foaming property allows it to be used in food scenarios that require foaming.

Non-toxicity and detoxification:

It is negative after acute toxicity and micronucleus tests, and is a non-toxic substance. ADI does not make special provisions, and LD50 ≥ 15g/kg (oral in mice).

It also has a significant detoxification effect on a variety of poisons (dimethoate, mercuric oxide, etc.), with high safety, which is conducive to application in food and other industries.

Rheological properties:

The viscosity of 10g/L flaxseed gum solution is about 0.02-0.08Pa・s. The viscosity increases with the increase of mass concentration and decreases with the increase of shear rate. The effect of temperature on its apparent viscosity conforms to the Arrhenius model, with an activation energy of 271.48kJ/mol.

The pH has a great influence. When the pH decreases under acidic conditions and increases under alkaline conditions, the apparent viscosity decreases and reaches a maximum value when it is neutral. These rheological characteristics make it adaptable to different processing environments and ensure product stability.

Water retention and antifreeze properties:

It has good water retention, and the water absorption ratio in sausages is 1:20, which can maintain strength and elasticity, so that the sausage body can be stored for a long time without releasing water, extending the shelf life; the antifreeze and anti-starch recovery functions are outstanding, and it is the best antifreeze property among edible gums, which can improve the antifreeze-thaw property of food, delay the crystallization rate during storage, and improve the shape and structure of products, such as ice cream and rice and flour products.

Thickening and suspension stability:

As a thickener, it can give the product a suitable viscosity and a refreshing and smooth taste. In the beverage, it can keep the tiny pulp particles evenly suspended for a long time, extending the shelf life.

The effect is better than some colloids. It can also form a stable complex structure with protein, starch, etc. to improve the stability of the food system.

Wide Range of Applications

Food industry​

Flaxseed gum is widely used in the food industry and can be called the “magic key” to improve food quality. It plays a vital role in the production of ice cream. The taste of ice cream depends largely on the size and distribution of ice crystals, and flaxseed gum can effectively inhibit the formation of ice crystals, making the texture of ice cream delicate, glutinous and smooth, as soft as silk.

Not only that, it can also improve the melting resistance and sudden heat resistance of ice cream. On hot summer days, even if ice cream is exposed to higher temperatures, it can maintain a relatively complete shape and will not melt quickly, allowing consumers to enjoy the coolness and sweetness.​

In the field of meat products, flaxseed gum also performs well. It is like a “quality guardian” of meat products. When flaxseed gum is added to meat products, it can reduce the loss of fat and meat flavor during cooking and retain the original flavor of meat to the greatest extent.

It can also improve the thermal stability of meat protein, myofibrillar protein and salt-soluble meat protein, enhance the gel strength of salt-soluble meat protein, make the structure of meat products more compact and chewier.

Adding flaxseed gum in the later stage of processing can also enhance the elasticity of meat products, make meat products full of toughness when chewing, and enhance rehydration, eliminate starch feeling, increase chewing feeling, and make meat products more delicious.

For beverages, flaxseed gum plays the role of “stabilizing elf”. After some fruit juices are left for a period of time, the fine pulp particles contained in them will sink, and the color of the juice will change, affecting the appearance.

Even after high-pressure homogenization, it is difficult to avoid this situation. When flaxseed gum is added to juice as a suspension stabilizer, it can make the fine pulp particles evenly suspended in the juice for a long time, extending the shelf life of the juice.

Other industries

In the pharmaceutical industry, flaxseed gum also has a unique use. It can be used as an adhesive to tightly bond various drug ingredients together to ensure the molding and stability of drug preparations.

At the same time, it can also act as a disintegrant. When the drug enters the human body, flaxseed gum can help the drug disintegrate quickly, allowing the drug ingredients to be released faster and absorbed by the human body, thereby improving the efficacy of the drug.

In the daily chemical industry, flaxseed gum has transformed itself into a “moisturizing star” and “thickening expert” in cosmetics. It can provide good moisturizing properties for cosmetics and keep the skin hydrated.

In terms of thickening, it can adjust the texture of cosmetics, making lotions thicker and creams more delicate, improving the use experience of cosmetics, and allowing consumers to feel a better texture when using cosmetics. ​

Production Process and Quality Control

The production process of flaxseed gum has a crucial impact on its quality. The industrial preparation process of flaxseed gum is mainly based on water extraction and alcohol precipitation, which is a common and classic extraction method.

This traditional water extraction method also has some limitations. For example, in the extraction process, factors such as temperature, time, material-liquid ratio and pH value of the extracting solution will have a significant impact on the extraction rate.

In addition to the water extraction and alcohol precipitation method, there are other emerging extraction technologies that are constantly developing and exploring. For example, the ultrasonic extraction of flaxseed gum has received widespread attention in recent years.

When using flaxseed cake as raw material for research, it was found that the extraction rate of the ultrasonic method was higher than that of the hot water extraction method. Ultrasonic extraction can utilize the cavitation effect of ultrasound to increase the contact area between flaxseed cells and solvents, thereby dissolving a larger amount of flaxseed gum.

Unlike the thick and complete structure of FSG extracted by hot water extraction, the structure of FSG extracted by ultrasound is thin and fragmented.

In terms of physical and chemical properties, the foaming, foam stability, emulsification and emulsification stability of ultrasonically extracted FSG are better than those of hot water extracted FSG.

The results of antioxidant test show that ultrasonically extracted FSG exhibits higher total reducing power and scavenging ability of hydroxyl radicals and DPPH free radicals, while hot water extracted FSG has higher scavenging ability of ABTS cationic free radicals. ​

In terms of quality control, there are strict quality indicators and specifications. The QB 2731-2005 standard has detailed provisions on the requirements, test methods, inspection rules and signs, packaging, transportation, storage, etc. of food additive flaxseed gum.

Development Prospects and Challenges

The development prospects of flaxseed gum are promising, driven by a global trend toward natural and healthy food consumption. This growing demand presents a favourable market environment for flaxseed gum, a natural food additive.

From a market perspective, research forecasts indicate that China’s flaxseed gum industry will experience accelerated growth from 2025 to 2030.

The market is expected to expand at an annual compound growth rate of 12%–15%, with the overall market size surpassing 8.5 billion yuan by 2030.

Internationally, demand for flaxseed gum is also rising steadily, with increasing recognition and adoption across various regions. Consequently, the global market for flaxseed gum is poised for continued expansion.

However, flaxseed gum also faces several challenges. In terms of market competition, despite its unique advantages, flaxseed gum competes with traditional food additives and emerging substitutes.

New synthetic colloids and other natural alternatives are emerging, posing potential threats to flaxseed gum in areas such as price and performance.

Technically, while progress has been made in the extraction and application of flaxseed gum, several challenges remain. The traditional water-extraction and alcohol precipitation process is energy-intensive and hinders further processing and utilisation of flaxseeds.

This not only increases production costs but also limits the efficient use of flaxseed resources. Additionally, further research is needed to enhance the modification and functionality of flaxseed gum to meet the diverse performance requirements of various industries.

Despite these challenges, ongoing research and technological advancements will continue to optimise flaxseed gum’s production process and expand its applications.

As a result, flaxseed gum is expected to be widely adopted across more sectors in the future, creating new opportunities for industry development, improving public health, and contributing significantly to industrial innovation.

Aloe-emodin usually appears as orange needle-shaped crystals (when crystallized from toluene) or earthy yellow crystalline powder (such as obtained from ethanol and other solvent-related operations), with a melting point of 223-224°C and the property of easy sublimation.

In terms of solubility, it is soluble in acetaldehyde, benzene, hot ethanol, dilute ammonia, sodium carbonate and sodium hydroxide aqueous solutions, especially in hot ethanol, yellow in ether and benzene, and crimson in ammonia and sulfuric acid. ​

In terms of natural sources, aloe-emodin is mainly extracted from aloe vera. Common aloe vera, striped aloe, Cape aloe, etc. are all important raw materials for extracting aloe-emodin.

In addition, it is also found in many plants such as the rhizomes of Rheum palmatum, the rhizomes of Rheum officinale, the rhizomes of Rumex barthianum, the leaves of Rumex dentata, the roots of the leguminous plants of the genus Silene, the seeds of Cassia tora, the seeds of Rhamnaceae, and the fruits of the Rhamnaceae plant Rhamnaceae. ​

Aloe-emodin has a long history of application in the medical field. In ancient times, Chinese medical scientists had already used its medicinal value.

With the development of modern science and technology, researchers have found that it has multiple biological activities, such as antioxidant, anti-inflammatory, and antibacterial. Today, aloe-emodin is widely used in medicine, health foods, cosmetics and other fields.

The Source of Aloe Emodin​

Aloe-emodin is widely found in many plants, especially in the Rheum genus of the Polygonaceae family and the Aloe genus of the Liliaceae family. In the Rheum genus of the Polygonaceae family, Rheum palmatum, Rheum tanguticum, and Rheum officinale are all common plants containing aloe-emodin. ​

Plants of the genus Aloe of the Liliaceae family are also an important source of aloe-emodin. Aloe vera, also known as American aloe, is a common medicinal aloe variety. Its leaves are thick and fleshy, rich in a variety of active ingredients, aloe-emodin being one of them.

Cape aloe is distributed in southern Africa, and its aloe-emodin content is also considerable. In local traditional medicine, it is often used to treat some diseases. As a native aloe variety in China, Chinese aloe is mainly distributed in Yuanjiang area of Yunnan, northern Hainan, and Leizhou Peninsula of Guangdong.

Although it is different from other aloe varieties in morphology and growth habits, it also contains aloe-emodin and has certain medicinal applications among the people.

In addition to the above plants, there are some other plants that also contain aloe-emodin. Although the main active ingredient of the leguminous plant senna is sennoside, it also contains a small amount of aloe-emodin. Senna is often used to treat constipation and digestive tract diseases, and the aloe-emodin in it may play a certain synergistic role in its efficacy.

Some plants of the genus Rumex in the Polygonaceae family, such as Rumex bartholina, have also been found to contain aloe-emodin. Although these plants are not the main raw materials for extracting aloe-emodin, their presence enriches the plant sources of aloe-emodin and provides more samples for further research on the distribution and biosynthesis pathway of aloe-emodin. ​

Extraction and Preparation Methods

Solvent extraction is a common method for extracting aloe-emodin from plants. This method uses the difference in solubility of aloe-emodin in different solvents to dissolve it from plant tissues. Taking the extraction of aloe-emodin from rhubarb as an example, ethanol is usually used as the extraction solvent.

This method is relatively simple to operate and has low equipment requirements. It is widely used in laboratories and industrial production, but it has disadvantages such as long extraction time and large solvent consumption. In addition, some impurities may be introduced during the extraction process, affecting the purity of aloe-emodin. ​

Ultrasound-assisted extraction is a more advanced extraction technology that uses the cavitation, mechanical and thermal effects of ultrasound to accelerate the release of aloe-emodin from plant cells into the solvent. The ultrasound time is generally 20-60 minutes.

Compared with the traditional solvent extraction method, ultrasound-assisted extraction can significantly shorten the extraction time, improve the extraction rate, and reduce the use of solvents. However, this method has high requirements for equipment and requires special ultrasonic equipment.

Parameters such as ultrasonic power and time need to be precisely controlled, otherwise it may affect the structure and activity of aloe-emodin.​

Supercritical fluid extraction is also a modern technology for extracting aloe-emodin, which uses supercritical fluid (such as carbon dioxide) as an extractant. Supercritical fluid has special properties between gas and liquid, with both high diffusivity and low viscosity of gas and high density and good solubility of liquid.

In the supercritical state, carbon dioxide can effectively dissolve target ingredients such as aloe-emodin, and after the extraction is completed, by reducing the pressure or increasing the temperature, carbon dioxide can be quickly gasified and separated, and will not remain in the extract, thereby obtaining high-purity aloe-emodin.

Supercritical fluid extraction has the advantages of high extraction efficiency, high product purity, and no pollution, but the equipment is expensive, the operating cost is high, and the operating technology requirements are also high. It is currently mainly used in laboratory research and fields with high requirements for product purity, and has not yet been widely used in industrial production.

The Physiological Activity of Aloe Emodin

Anti-tumor activity

Aloe-emodin has shown remarkable potential in the field of anti-tumor. Many studies have shown that it has a significant inhibitory effect on a variety of cancer cells. In the study of neuroectodermal tumors, aloe-emodin can interfere with the normal metabolic process of cancer cells and inhibit their proliferation and spread.

For liver cancer cells, it can induce cancer cell apoptosis and promote cancer cell death by activating the intracellular apoptotic signaling pathway.

The anti-tumor mechanism of aloe-emodin mainly includes inhibiting the synthesis of cancer cell DNA, RNA and protein. The rapid proliferation of cancer cells depends on the vigorous nucleic acid and protein synthesis process. Aloe-emodin can act on the key enzymes and signaling pathways in these synthesis processes to block their synthesis.

It can inhibit the activity of DNA polymerase, hinder the replication process of cancer cell DNA, and thus prevent normal cell division. Aloe-emodin can also affect factors related to RNA transcription, interfere with RNA synthesis, further affect the protein translation process, and ultimately inhibit the growth and proliferation of cancer cells.

Antibacterial activity

Aloe-emodin has a wide antibacterial spectrum and has inhibitory effects on many bacteria. Among Gram-positive bacteria, Staphylococcus and Streptococcus are more sensitive to it. Staphylococcus aureus is a common pathogen that can cause a variety of infectious diseases.

Aloe-emodin can effectively inhibit its growth. Aloe-emodin also has a certain inhibitory effect on some conditional pathogens such as Corynebacterium diphtheriae, Bacillus subtilis and Bacillus anthracis. ​

The antibacterial mechanism of aloe-emodin is mainly related to the inhibition of electron transfer in the mitochondrial respiratory chain. The energy metabolism of bacteria mainly depends on the electron transfer process of the mitochondrial respiratory chain.

Aloe-emodin can act on key enzymes and electron carriers in the respiratory chain, block electron transfer, and prevent bacteria from producing enough energy, thereby inhibiting their growth and reproduction. It can also have a strong inhibitory effect on the nucleic acid and protein synthesis of Staphylococcus aureus, further affecting the normal physiological function of bacteria.

Immune regulatory effect

Aloe-emodin has a complex regulatory effect on the immune system and plays different roles in different immune states. In immune hypersensitivity reactions, it can inhibit the production of antibodies in the organism, thereby inhibiting immune hyperactivity and playing an anti-allergic role.

Aloe-emodin can also regulate the function of immune cells. It can reduce the number of white blood cells, reduce the weight of immune organs, and inhibit the phagocytic function of peritoneal macrophages.

However, the regulatory effect of aloe-emodin on the immune system is not a single inhibitory effect. In some cases, it may also play an immune-enhancing role. When the body’s immunity is low, an appropriate dose of aloe-emodin can stimulate the activity of immune cells and improve the body’s immune defense ability.

Studies have found that in an infection model, low doses of aloe-emodin can enhance the bactericidal ability of macrophages and improve the body’s resistance to pathogens. This two-way regulatory effect makes aloe-emodin have potential application value in the treatment of immune-related diseases, but it also requires precise control of its dosage and timing to achieve the best therapeutic effect. ​

Laxative effect​

Aloe-emodin has strong laxative activity. Its main mechanism of action is to stimulate intestinal peristalsis and change the osmotic pressure in the intestine to promote defecation. When aloe-emodin enters the human body, it is metabolized by intestinal bacteria into rhein and rhein anthrone in the intestine.

These metabolites can directly stimulate the intestinal nerve plexus, cause intestinal smooth muscle contraction, and enhance intestinal peristalsis. Aloe-emodin and its metabolites also increase the osmotic pressure in the intestine, allowing more water to enter the intestine, softening feces, and facilitating the discharge of waste in the intestine, thereby achieving a stimulating laxative effect. ​

This stimulating laxative effect has a special effect on patients with constipation and hemorrhoids, especially for middle-aged and elderly constipation. As the intestinal function of middle-aged and elderly people gradually declines, constipation problems are prone to occur.

The laxative effect of aloe-emodin can effectively improve their defecation. However, it should be noted that aloe-emodin has a strong laxative effect. When used, the dosage should be strictly controlled to avoid adverse reactions such as diarrhea and dehydration.

People with weak constitutions, pregnant women, breastfeeding women, and those with intestinal diseases should use products containing aloe-emodin with caution or avoid using them to avoid adverse effects on their health.

Other physiological activities

Aloe-emodin has a certain antioxidant effect, which can remove free radicals in the body and reduce the damage to cells caused by oxidative stress.

Functional groups such as hydroxyl groups in aloe-emodin molecules can provide hydrogen atoms, combine with free radicals, make them inactive, and thus protect cells from oxidative damage.

In terms of liver protection, aloe-emodin can reduce the damage to the liver caused by chemicals, drugs, etc. It can regulate the metabolic function of the liver and promote the repair and regeneration of liver cells.

Its mechanism of action may be related to regulating the antioxidant system in the liver, inhibiting inflammatory responses, and regulating cell apoptosis-related signaling pathways. ​

Aloe-emodin also has certain research results in lipid-lowering and weight loss. It can inhibit the absorption of cholesterol and reduce the accumulation of fat in the body. At the same time, because it can promote intestinal peristalsis, speed up the emptying of food in the intestine, and reduce the absorption of fat and calories, it helps to lose weight.

Application areas of aloe-emodin​

Medical field​

Aloe-emodin has shown great potential in the field of drug research and development. Based on its multiple physiological activities, it has been used in the preparation of a variety of drugs.

In terms of antibacterial drugs, since aloe-emodin has an inhibitory effect on Staphylococcus, Streptococcus, Paratyphoid Bacillus, Shigella dysenteriae and other bacteria, it is used to develop new antibacterial drugs to cope with the increasingly serious problem of bacterial resistance.

In the development of anti-tumor drugs, aloe-emodin is often used as an auxiliary drug. It can inhibit the proliferation of cancer cells and induce apoptosis of cancer cells. When used in combination with traditional chemotherapy drugs, it can enhance the effect of chemotherapy and reduce the dosage and side effects of chemotherapy drugs.

This is because aloe-emodin can regulate the signaling pathways of cancer cells, making cancer cells more sensitive to chemotherapy drugs, and at the same time reducing the damage of chemotherapy drugs to normal cells. ​

In clinical applications, aloe-emodin has also achieved some positive results. In the treatment of certain infectious diseases, drugs containing aloe-emodin can effectively relieve symptoms and shorten the course of the disease.

In a clinical study on bacillary dysentery, patients were treated with drugs containing aloe-emodin, and their diarrhea, abdominal pain and other symptoms were significantly improved in a short period of time, and the number of bacteria in the feces was also significantly reduced.

In the treatment of some inflammatory skin diseases, the anti-inflammatory and antibacterial effects of aloe-emodin also play an important role, which can reduce skin inflammation and promote wound healing.

The field of health care products​

As a health care ingredient, aloe-emodin plays an important role in improving intestinal function and enhancing immunity. Because it has a laxative effect, it can stimulate intestinal wall peristalsis, change the osmotic pressure in the intestine, and promote defecation, so it is often used to make health care products to improve constipation.

Aloe-emodin also has a certain immunomodulatory effect, which can enhance the body’s immunity and prevent diseases. It can regulate the activity of immune cells and promote the secretion of immune factors, thereby improving the body’s immune defense ability.

In some health care products, aloe-emodin is combined with other nutrients such as vitamins and minerals to make comprehensive nutritional supplements, which can improve intestinal function while enhancing the body’s overall immunity.

At present, the aloe-emodin health care products on the market cover a variety of dosage forms such as capsules, tablets, and oral liquids to meet the needs of different consumers. ​

Cosmetics field​

In the cosmetics field, aloe-emodin is highly favored for its excellent efficacy. It has multiple functions such as anti-inflammatory, moisturizing, and anti-oxidation, and can effectively improve skin conditions.

When the skin is infected by bacteria and causes inflammation, aloe-emodin can inhibit the growth and reproduction of bacteria, relieve inflammation symptoms, and promote skin repair. ​

Aloe-emodin also has a significant moisturizing effect. It can combine with the moisture in the skin to form a moisturizing film to prevent moisture loss and keep the skin moisturized.

This feature makes it an important ingredient in many moisturizing skin care products, such as moisturizing lotions and creams. In terms of antioxidants, aloe-emodin can remove free radicals in the body, reduce the damage of free radicals to skin cells, and delay skin aging.

Aloe-emodin can provide hydrogen atoms, combine with free radicals, and make them inactive, thereby protecting skin cells from oxidative damage and maintaining the elasticity and luster of the skin. ​

There are many cosmetics containing aloe-emodin on the market, covering multiple categories such as skin care and hair care. Consumers’ demand for natural and healthy cosmetics continues to increase. As a natural plant extract, aloe-emodin meets this consumption trend and its share in the cosmetics market is expected to further expand. ​

The Safety and Precautions of Aloe Emodin​

Toxicity and adverse reactions​

Although aloe-emodin has a variety of beneficial physiological activities, its safety should also be paid attention to during use. From the perspective of toxicity, aloe-emodin has certain toxicity.

When ingested in large quantities, it may cause a series of adverse reactions. Among them, gastrointestinal reactions are more common, such as diarrhea, nausea, vomiting, etc. At the same time, its stimulation of the gastrointestinal mucosa may also cause nausea and vomiting symptoms.

Aloe-emodin may also affect the nervous system. Studies have shown that excessive intake may cause the nervous system to be stimulated, thereby affecting sleep quality and causing insomnia. In terms of skin contact, some people are at risk of allergies to aloe-emodin, and allergic reactions such as itching, redness, swelling, and rash may occur after contact.

Precautions for Use

When using products containing aloe-emodin, be sure to strictly control the dosage. Whether it is used as a medicine, health product or cosmetic ingredient, it should be used according to the product instructions or the doctor’s advice, and avoid increasing the dosage on your own.

People with allergies should perform a skin test before use, especially when using cosmetics containing aloe-emodin. You can apply a small amount of the product to sensitive areas of the skin such as behind the ear or the inside of the wrist, and observe for 24-48 hours. If there is no allergic reaction such as redness, swelling, itching, etc., it can be used normally.

Research Status and Prospects

Research status

At present, the research on aloe-emodin has achieved remarkable results in many aspects. In the study of physiological activity, in addition to the clear anti-tumor, antibacterial, immunomodulatory, laxative and other effects, the research on its antioxidant, liver protection, lipid-lowering and weight-loss activities is also deepening.

The research methods have gradually expanded from traditional cell experiments and animal experiments to molecular biology, gene sequencing and other levels to reveal its mechanism of action in more depth.

In terms of mechanism research, although it has been known that aloe-emodin plays a role in anti-tumor by inhibiting the synthesis of cancer cell DNA, RNA and protein, its specific regulatory mechanism in the complex signal pathways in cells still needs to be further clarified.

In the antibacterial mechanism, in addition to inhibiting the electron transfer of the mitochondrial respiratory chain, the study of its interaction with bacterial cell membranes, cell walls, etc. is also gradually being carried out. ​

In terms of application development, the research on aloe-emodin in the medical field is mainly focused on the development of new drugs, and attempts are made to develop new drugs with aloe-emodin as the main ingredient or auxiliary ingredient for the treatment of cancer, infectious diseases, immune-related diseases, etc.

In terms of extraction and preparation technology, although traditional solvent extraction methods are still widely used, new technologies such as ultrasound-assisted extraction and supercritical fluid extraction are also being continuously optimized and promoted to improve extraction efficiency and product purity. ​

Future Outlook

In terms of new drug development, aloe-emodin has broad application prospects. With the in-depth study of its mechanism of action, it is expected that more highly efficient and low-toxic anticancer drugs will be developed, especially for some types of cancer that are currently poorly treated.

Aloe-emodin can be combined with other synergistic drug ingredients to develop compound preparations to improve the therapeutic effect.

In terms of functional food development, aloe-emodin can be used as a functional ingredient and added to more foods, such as yogurt, beverages, cakes, etc., to develop healthy foods with the effects of improving intestinal function, enhancing immunity, and anti-oxidation.

The stability and bioavailability of aloe-emodin in food can be improved by means of microencapsulation and nanotechnology. ​

In terms of cosmetic innovation, aloe-emodin, as a natural plant extract, will play a greater role in the cosmetics field. More cosmetics with special effects can be developed, such as soothing and repairing products for sensitive skin, anti-wrinkle and firming products, etc.

Advanced formulation technology and carrier technology can be used to improve the activity and stability of aloe-emodin in cosmetics so that it can better exert its efficacy.

In daily life, cinnamon is a common spice in the kitchen. Whether it is the cinnamon rolls in Western baking, which exude sweetness and warmth, or the small piece added to Chinese stewed meat, which adds a unique flavor to the dishes, it plays an important role in flavoring and is deeply loved by people.

But have you ever thought that this familiar cinnamon, after extraction, is quietly emerging in the fields of medicine and health care, and has become a new darling in the scientific research community? ​

With the rapid development of scientific research technology, scientists have gradually deepened their research on cinnamon and found that the substances extracted from cinnamon contain huge value and show exciting potential in many fields.

From basic component analysis, to the exploration of mechanism of action, to the research of practical applications, the mystery of cinnamon extract is being unveiled bit by bit.

Source and Process of Cinnamon Extract​

Cinnamon extract, as the name implies, is the essence extracted from the dried bark of cinnamon, a plant of the Lauraceae family. As a plant, cinnamon mainly grows in warm and humid southern regions, such as Guangxi and Guangdong, where the unique climatic conditions provide a high-quality environment for the growth of cinnamon.

Cinnamon trees are evergreen all year round, and the bark presents a unique gray-brown color, exuding a strong aromatic smell.

The extraction process of cinnamon extract has strict operating steps. First, mature cinnamon bark is collected, carefully selected, and impurities are removed to ensure the purity of the raw materials. Then, the selected cinnamon bark is crushed into fine particles to increase its contact area with the solvent and improve the extraction efficiency.

After that, the crushed cinnamon bark particles are usually soaked in a specific solvent so that the active ingredients are fully dissolved in the solvent. After the extraction is completed, the residue is filtered to remove the residue, and a filtrate containing the active ingredient is obtained.

Then, the solvent in the filtrate is removed by evaporation and other methods to concentrate the extract. After drying, a common cinnamon extract is obtained, which can be in the form of powder or paste, which is convenient for storage and subsequent use.

Main Components of Cinnamon

Cinnamon extracts are rich in ingredients, among which volatile oils are an important component, with a content of about 1%-2 %. In some high-quality extracts, this content can even reach 5.86%. Volatile oils give cinnamon extracts a unique aroma that is unforgettable.

Among volatile oils, cinnamaldehyde is the most critical component, usually accounting for 52.92% – 61.20%. It is not only the main source of cinnamon aroma, but also has a variety of pharmacological activities. It is one of the core substances for cinnamon to exert its efficacy.

In addition to cinnamaldehyde, volatile oils also contain a small amount of cinnamyl acetate, eugenol and other ingredients. These ingredients work together to form the complex and unique aroma and characteristics of cinnamon extracts. ​

In cinnamon extracts, there are also some other ingredients, such as organic acids such as cinnamic acid and ethyl phenylpropionate, as well as diterpenoid compounds such as cinnamyl alcohol, anhydrous cinnamyl alcohol, and acetyl cinnamyl alcohol. Although these components are present in relatively small amounts, they play an integral role in the overall efficacy of cinnamon extract.

The Power of Cinnamon Extract​

Cinnamon extract is a concentrate of a popular spice obtained from the bark of cinnamon trees, especially true cinnamon (Cinnamomum verum) and cassia (Cinnamomum cassia). It has been used in traditional medicine for centuries, and modern research is beginning to confirm its many benefits. Here’s a closer look at its potential benefits:

Regulate blood sugar and help diabetics

For diabetic patients, stable control of blood sugar is crucial. Cinnamon extract has shown remarkable effects in this regard. It can promote the secretion of insulin, just like injecting vitality into the blood sugar regulation “helper” in the body, allowing insulin to work better. At the same time, cinnamon extract can also enhance insulin sensitivity, making cells more sensitive to insulin, so that glucose can be absorbed and utilized more effectively, keeping blood sugar levels in a relatively stable state.

Antibacterial and anti-inflammatory, health shield

Cinnamon extract also has strong antibacterial and anti-inflammatory capabilities. It is like a healthy shield for the body, which can resist the invasion of various bacteria. Studies have found that cinnamon extract has a significant inhibitory effect on common bacteria such as Escherichia coli and Staphylococcus aureus.

When these bacteria try to “make trouble” in the human body or other environments, the active ingredients in cinnamon extract can destroy the bacterial cell membrane, just like piercing the “protective membrane” of the bacteria, making it impossible for the bacteria to survive and reproduce normally, thereby reducing the risk of infection. ​

In the medical field, the antibacterial properties of cinnamon extract have received widespread attention. In terms of food preservation, cinnamon extract is also very useful.

For example, adding cinnamon extract to some meat processing can extend the shelf life of meat products, maintain their freshness and flavor, reduce food spoilage caused by bacterial growth, and make consumers eat more assured.

The guardian of cardiovascular system​

Cardiovascular disease is a major “killer” threatening human health, and cinnamon extract has an outstanding performance in preventing and improving cardiovascular disease. It can lower the cholesterol and triglyceride levels in the blood, clean up the “garbage” in the blood vessels, and make the blood flow smoother.

At the same time, cinnamon extract can inhibit the aggregation of platelets and prevent the formation of blood clots, just like putting a “safety lock” on the blood vessels, reducing the risk of cardiovascular blockage.

In addition, it also has the effect of dilating peripheral blood vessels, keeping blood vessels elastic, lowering blood pressure, and protecting cardiovascular health in all directions.

A good helper for digestion​

In daily life, many people may encounter problems such as indigestion, bloating, and stomach pain, and cinnamon extract can be a good helper for our digestion.

It can stimulate gastrointestinal motility, just like injecting “power” into the stomach and intestines, allowing food to be digested and absorbed faster in the gastrointestinal tract.

At the same time, cinnamon extract can also enhance the secretion of digestive juices, such as gastric juice and intestinal juice. These digestive juices are like “catalysts” for food digestion, which can better decompose food and improve digestion efficiency. ​

Brain Energy Booster​

As people age, their memory and attention may gradually decline, and they may even face the threat of neurological diseases such as Alzheimer’s disease.

Some antioxidants contained in cinnamon extract are like the “guardian” of the brain, which can protect nerve cells from damage by free radicals and maintain the normal function of nerve cells.

At the same time, these antioxidants can also promote signal transmission between nerve cells, making the brain’s “information highway” more unobstructed, thereby improving memory and attention. ​​

Diversity of Application Areas​

Emerging in the pharmaceutical field​

In the field of medicine, cinnamon extract is gradually becoming a hot spot for research and development. Many scientific research teams are committed to developing medicines and health products with cinnamon extract as the main ingredient.

In the research and development of hypoglycemic drugs, cinnamon extract has become an important research direction due to its effect of regulating blood sugar.

Some pharmaceutical companies have tried to combine cinnamon extract with other hypoglycemic ingredients to develop compound preparations to improve the treatment effect and provide more treatment options for diabetic patients.

For erectile dysfunction, a common male disease, cinnamon extract has also shown potential therapeutic value. Studies have found that certain components in cinnamon extract can significantly inhibit PDE5A protein, which is closely related to the mechanism of action for the treatment of erectile dysfunction.

At present, there are related patents and research reports that provide theoretical support for the development of new drugs for the treatment of erectile dysfunction.

In terms of intestinal health, cinnamon extract has a protective effect on the intestinal mucosa, can reduce intestinal inflammation, and promote the growth of beneficial intestinal bacteria.

Some studies have applied cinnamon extract to the development of drugs for the treatment of intestinal diseases such as enteritis and diarrhea, which is expected to bring new treatment options for patients with intestinal diseases.

Adding color and flavor to the food industry​

In the food industry, cinnamon extract has a wide range of applications. As a natural spice, it can add a unique flavor to a variety of foods.

In baked goods, whether it is sweet bread or crispy biscuits, adding cinnamon extract can exude a rich aroma, which greatly increases people’s appetite. Like the classic cinnamon roll, the unique sweet taste is largely due to cinnamon extract.

In the field of beverages, cinnamon extract also shows its prowess. It can add a different flavor to beverages such as coffee and tea.

For example, adding a little cinnamon extract to latte can instantly enhance the layering and unique taste of the beverage. Adding cinnamon extract to juice drinks can also play a certain preservative role and extend the shelf life of the beverage.

In meat processing, cinnamon extract also plays an important role. It not only adds flavor to meat products, but also acts as a natural preservative to inhibit bacterial growth, extend the shelf life of meat products, and reduce food spoilage problems caused by microbial contamination, so that consumers can eat more assured.

Other potential applications

In addition to the medical and food fields, cinnamon extract also has potential application value in other areas. In the field of cosmetics, due to its antioxidant and anti-inflammatory properties, cinnamon extract is believed to be used to develop skin care products with anti-aging and anti-wrinkle effects.

It can remove free radicals in the skin, reduce oxidative damage to skin cells, delay skin aging, reduce skin inflammation, and improve skin health.

Precautions for Use​

Applicable people and contraindications

Although cinnamon extract has many benefits, it is not suitable for everyone. For people with high blood sugar, cinnamon extract is a good choice. It can help regulate blood sugar and help maintain blood sugar at a relatively stable level, so that diabetic patients have an additional health guarantee in addition to diet.

People with low immunity can also appropriately supplement cinnamon extract. The various ingredients it contains can enhance the body’s resistance, resist the invasion of external pathogens, and reduce the risk of illness.

For people with weak digestive function, such as those who often have bloating and indigestion, cinnamon extract can stimulate gastrointestinal motility, enhance digestive juice secretion, improve digestive function, and allow food to be better digested and absorbed. ​

However, pregnant women should avoid using cinnamon extract. This is because cinnamon extract is hot in nature, which may cause excessive heat in pregnant women, cause fetal movement and even increase the risk of miscarriage. For the health of the fetus, pregnant women need to be cautious.

People with Yin deficiency and excessive fire should not use it. This kind of people have insufficient Yin fluid in their bodies and excessive Yang Qi.

After using cinnamon extract, it will further promote the heat evil in the body, aggravating symptoms such as five heart irritability, insomnia, night sweats, dry mouth and throat.

Patients with fever should also stay away from cinnamon extract. Fever is mostly caused by exogenous warm evil or excessive Yang heat in the body. Using cinnamon extract will worsen the condition and is not conducive to the body’s recovery.

Safe dosage control

When using cinnamon extract, it is crucial to control the safe dose. Generally speaking, the recommended safe daily intake for adults is about 0.4 grams. But this is not an absolute standard.

The specific intake needs to be adjusted under the guidance of a doctor or professional according to personal physical condition, age, weight and other factors. If cinnamon extract is taken in excess, it may cause a series of side effects.

When using cinnamon extract, we must also keep in mind the applicable population and taboos, strictly control the safe dose, and ensure its safety and effectiveness.

In the future, with the continuous deepening of scientific research, it is believed that the potential of cinnamon extract in more fields will be further explored, providing new ideas and methods for solving more health problems and social needs.

It is expected to play a greater role in the development of new drugs, the development of functional foods, the development of green agriculture, and other aspects, and bring more benefits to human health and sustainable development.

Hericium erinaceus, as a precious medicinal and edible mushroom, has a long history of being used as food and medicine in my country. It belongs to the genus Hericium of the family Odontaceae. The fruiting body is blocky, flat, hemispherical or head-shaped, tender and tender, and the diameter is usually between 5 and 15 cm.

Hericium erinaceus is rich in various nutrients, such as protein, unsaturated fatty acids, minerals and vitamins, which are of great benefit to human health. At the same time, it also contains polysaccharides, polypeptides and fat substances, which can inhibit the synthesis of genetic material in cancer cells and play a certain role in the prevention and treatment of digestive tract cancer and other malignant tumors. ​

And the glucan in Hericium erinaceus extract has been the focus of scientific research and health in recent years. As a polysaccharide, glucan is widely found in microorganisms, plants and animals. In Hericium erinaceus, it has a unique structure and function, which adds a strong touch to the health and medicinal value of Hericium erinaceus. Next, let us explore the mystery of Hericium erinaceus extract – glucan. ​

The Structural Code of Glucan

The secrets of molecular composition

The molecular structure of Hericium erinaceus glucan is like a carefully constructed microscopic building, and its basic unit is glucose. Through advanced chemical analysis technology, researchers found that Hericium erinaceus glucan is completely composed of glucose and is a homogeneous glucan.

The connection between these glucose units, that is, the type and position of glycosidic bonds, determines the main chain and branch chain structure of glucan. This unique main and branch chain structure, like steel beams with different directions and connection methods in a building, gives Hericium erinaceus glucan unique physical and chemical properties.

Unique triple helix structure

Hericium erinaceus glucan is not only unique in its primary structure, but also has amazing features in its advanced structure. Through the Congo red experiment, researchers discovered the unique triple helix structure of Hericium erinaceus glucan.

Compared with other mushroom glucans, the triple helix structure of Hericium erinaceus glucan has both similarities and unique differences in stability and functional performance.

The triple helix structure of Hericium erinaceus glucan may have different mechanisms of action in maintaining its biological activity. This triple helix structure may exert its biological activities, such as immunomodulation and anti-tumou,r by affecting the binding mode of glucan to cell surface receptors or regulating its metabolic pathways in the body.

Extraction Technology Revealed

Traditional extraction method​

In the extraction process of Hericium erinaceus glucan, traditional extraction methods occupy an important historical position, and hot water extraction is one of the most widely used methods. Its operation process is relatively intuitive.

First, the Hericium erinaceus fruiting body is crushed to make its particle size meet certain requirements so that the subsequent extraction process can be carried out more fully. Then, according to a certain material-liquid ratio, the Hericium erinaceus powder is mixed with water and extracted at a specific temperature.

The advantages of the hot water extraction method are very significant. It is simple to operate, does not require complex instruments and equipment and advanced technical knowledge, and can be easily carried out by ordinary laboratories or production companies.

However, this method also has some disadvantages that cannot be ignored. The polysaccharides in Hericium erinaceus are mainly concentrated in the cell wall. During hot water extraction, the polysaccharides in the cell wall are not fully released, resulting in a low yield of glucan, which is difficult to meet the needs of efficient production.

Moreover, a large amount of impurities will be dissolved during the hot water extraction process. These impurities may include proteins, pigments, small molecular sugars, etc., which require cumbersome separation and purification steps in the subsequent process, increasing production costs and process complexity. ​

In addition to hot water extraction, alkali extraction is also a traditional extraction method. During alkaline extraction, Hericium erinaceus fruiting bodies are crushed and then extracted with an alkaline solution of a certain concentration. However, alkaline extraction also has problems.

Under dilute alkaline conditions, the glycosidic bonds of glucan may break, and some polysaccharides may be hydrolyzed, thereby reducing the extraction rate of polysaccharides. In addition, the extract contains a lot of impurities, making subsequent purification difficult.

Modern innovative technology

Steam explosion wall breaking combined with water extraction and alcohol precipitation technology is one of the best. Through this technology, the utilization rate of Hericium erinaceus fruiting body polysaccharides can be greatly improved.

The steam explosion wall breaking Hericium erinaceus fruiting body polysaccharides are rich in β-glucan, and have the advantages of no chemical residue, low cost, and high raw material utilization. ​

There is also alkali extraction and acid hydrolysis technology, which cleverly combines the advantages of alkali extraction and acid hydrolysis. This method can not only remove α-glucan, but also solve the problem of poor water solubility of β-glucan.

The obtained Hericium erinaceus fruiting body polysaccharide has a high β-glucan content, an average molecular weight between 2000-200,000 Daltons, and good water solubility, which provides a broader space for the application of Hericium erinaceus glucan. ​

Compound enzyme-assisted hot water extraction is also an effective innovative technology. The complex enzyme can specifically decompose the components in the cell wall of Hericium erinaceus and promote the release of glucan.

At the same time, hot water extraction further improves the extraction rate. This method provides new ideas and methods for the extraction of Hericium erinaceus glucan and shows good application prospects.

The anti-inflammatory properties of Hericium erinaceus glucan provide new options and hope for the prevention and treatment of inflammation-related diseases.​

Significant gastrointestinal protective effect

The gastrointestinal tract is an important place for human digestion and absorption, and is also an important part of the human immune system. Hericium erinaceus extract – glucan has a significant protective effect on the gastrointestinal tract and is known as the “guardian” of the gastrointestinal tract.

It can repair damaged gastric mucosa, promote the proliferation and regeneration of gastric mucosal cells, and enhance the defense function of gastric mucosa, thereby effectively preventing and treating gastrointestinal diseases such as gastric ulcers and gastritis.

Potential other benefits

In addition to the above-mentioned clear effects, Hericium erinaceus extract – glucan also shows potential in anti-oxidation, lowering blood lipids, and anti-cancer. Although related research is still in-depth, some remarkable progress has been made. ​

In terms of anti-oxidation, Hericium erinaceus glucan has the ability to scavenge free radicals. Certain structures in Hericium erinaceus glucan can bind to free radicals, making them inactive, thereby reducing the damage of free radicals to cells.

This shows that Hericium erinaceus glucan has certain potential in anti-oxidation and anti-aging, and is expected to become a natural antioxidant for use in food, health care products and other fields. ​

In terms of lowering blood lipids, some studies have preliminarily shown that Hericium erinaceus glucan may affect the synthesis, transport and decomposition of lipids by regulating the activity of lipid metabolism-related enzymes, thereby reducing blood lipid levels.

In recent years, there has been a growing interest in natural supplements that support and boost the immune system. Among them, astaxanthin, a powerful antioxidant derived from microalgae, has received much attention for its potential health benefits, especially in terms of boosting immune function.

Known for its exceptional antioxidant properties, astaxanthin offers a natural solution for supporting immune health, reducing inflammation, and promoting overall well-being.

So, what exactly is astaxanthin? And how does it help boost the immune system? In this blog, we’ll dive into the science behind this energizing pigment and explore its benefits for immune health.

The Source of Astaxanthin

The sources of astaxanthin are mainly divided into two ways: natural extraction and artificial synthesis. There are many differences between the two in terms of structure, properties and application. ​

Natural astaxanthin has a rich variety of biological sources, mainly including algae, fungi and crustaceans. In algae, such as Euglena sanguineus, the astaxanthin content can reach 0.5% of the cell dry weight, but the growth is extremely slow and requires a long cultivation cycle.

Haematococcus pluvialis is currently the most concerned algae source. It can be called a “rich mine” of astaxanthin, and the maximum accumulation can reach 4% of the cell dry weight.

The process of extracting astaxanthin from Haematococcus pluvialis is usually to first cultivate Haematococcus pluvialis on a large scale under suitable conditions, and then extract and purify it by physical or chemical methods after it accumulates a large amount of astaxanthin.

Although this process has high technical requirements, the obtained astaxanthin is of excellent quality and is highly favored in the market. ​

Phaffia rhodozyma in fungi is also an important producer of natural astaxanthin. Phaffia rhodozyma can grow rapidly under a variety of carbon and nitrogen sources. Wild Phaffia rhodozyma contains about 200-500μg of carotenoids per gram of dry yeast, of which 90% is astaxanthin.

Compared with algae and crustaceans, it has a unique advantage in that it can be rapidly metabolized in a fermenter and achieve high cell density production.

Crustaceans, such as shrimp and crab, are also natural hosts of astaxanthin. Astaxanthin is extracted from crustaceans, mainly recovered from waste from aquatic product processing. However, astaxanthin in crustacean shells mainly exists in the form of esters, and the content is not high.

Artificially synthesized astaxanthin is produced by chemical methods using carotene as raw material. Although artificial synthesis can meet the market demand for astaxanthin to a certain extent, and the cost is relatively low and the yield is stable.

However, its synthesis process is complicated and often requires the use of multiple chemical reagents and catalysts, which may introduce impurities and lead to poor product stability. Moreover, artificially synthesized astaxanthin is a mixture of multiple isomers, and there is some controversy in terms of biological activity and safety compared to natural astaxanthin.

The Powerful Effects of Astaxanthin​

Antioxidant: The nemesis of free radicals​

Free radicals refer to atoms, molecules or ions with unpaired electrons. They are extremely active in chemical properties and are always looking for electrons from other substances in the body to achieve their own stability.

When free radicals attack human cells, they trigger a series of chain reactions, causing damage to the cell membrane, causing the cell to lose its normal physiological function, destroying the protein structure, affecting its normal physiological activity, and even damaging DNA, which may cause gene mutations and increase the risk of cancer.

The reason why astaxanthin can become the nemesis of free radicals is closely related to its unique molecular structure. Astaxanthin molecules contain multiple conjugated double bonds, which can attract unpaired electrons of free radicals like “electron sponges” or provide electrons to free radicals, thereby making free radicals stable and no longer aggressive.

At the same time, the six-membered ring structure of α-hydroxyketone at both ends of the astaxanthin molecule further enhances its ability to capture free radicals.

Many studies have shown that the antioxidant capacity of astaxanthin is “unique”. It is a powerful quencher of singlet oxygen, and its antioxidant activity is 550 times that of vitamin E and 10 times that of carotenoids such as β-carotene, lutein, canthaxanthin and zeaxanthin. It is known as “super vitamin E” and “super antioxidant”.

At the cellular level, astaxanthin also plays an important antioxidant role. Various biological membranes in cells, such as cell membranes and mitochondrial membranes, are rich in unsaturated fatty acids and are extremely vulnerable to free radical attacks.

Astaxanthin can be arranged across the membrane in the lipid bilayer of the cell membrane, like a solid “protective shield”, allowing reactive oxygen species (ROS) to shuttle along the double bonds on its carbon skeleton and promote transmembrane transfer of electrons. In this way, astaxanthin can not only prevent ROS from oxidative damage to cell membranes, but also protect various organelles in cells and maintain the normal physiological functions of cells.

Enhance immunity: strengthen the health defense line

The immune system is an important line of defense for the human body against diseases, and astaxanthin plays a key role in regulating the immune system. Its mechanism of action is mainly reflected in multiple aspects. ​

Astaxanthin can enhance the activity of T cells, neutrophils, natural killer cells and B cells. Astaxanthin regulates the activity of these immune cells so that they can play a better role, thereby enhancing the combat effectiveness of the entire immune system.

Astaxanthin can also further enhance the immunity of the organism by promoting the secretion of cytokines or the production of immunoglobulins.

Astaxanthin can stimulate immune cells to secrete more cytokines, such as interleukins and interferons, which can activate other immune cells and enhance immune responses. At the same time, astaxanthin can also promote the production of immunoglobulins and improve the body’s specific recognition and clearance of pathogens.

Preventing cardiovascular disease: Guardian of blood vessels

Cardiovascular disease is the “number one killer” threatening human health worldwide, and a large number of people lose their lives due to cardiovascular disease every year.

Astaxanthin, as a powerful antioxidant, plays an important role in preventing cardiovascular disease. It can increase the level of high-density lipoprotein (HDL). HDL is like a “scavenger” in the blood vessels, which can transport cholesterol from peripheral tissues back to the liver for metabolism, thereby reducing the cholesterol content in the blood and reducing the deposition of cholesterol in the blood vessel wall.

At the same time, astaxanthin can also reduce LDL levels, reduce the oxidative modification of LDL, reduce the formation of ox-LDL, and prevent the occurrence of atherosclerosis from the source.

Astaxanthin also has anti-inflammatory effects and can reduce the inflammatory response of the vascular endothelium. Inflammation is one of the important factors in the occurrence and development of atherosclerosis.

Astaxanthin inhibits inflammatory signaling pathways and reduces the release of inflammatory mediators, such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), etc., thereby alleviating the inflammatory state of the vascular endothelium and protecting the endothelial function.

Many research results and actual cases have confirmed the effectiveness of astaxanthin in preventing cardiovascular diseases. In real life, some people at high risk of cardiovascular diseases who have been taking astaxanthin health supplements for a long time, such as obese people, hypertensive patients, and diabetic patients, have significantly reduced the risk of cardiovascular diseases.

Their blood pressure, blood lipids and other indicators have been better controlled, and their quality of life has also been significantly improved.

Other benefits: A versatile health booster​

In addition to the above powerful effects, astaxanthin is also a “all-rounder” and plays an important role in relieving sports fatigue, anti-inflammatory, and protecting eyes. ​

Astaxanthin can act as an antioxidant to inhibit the oxidative damage of free radicals to the body. Oral astaxanthin can also enhance aerobic metabolism, increase muscle strength and muscle tolerance.

Inflammation is the common pathological basis of many diseases, and astaxanthin has significant anti-inflammatory effects. It can reduce the release of inflammatory mediators and alleviate inflammatory responses. It has a positive effect on relieving the symptoms of inflammatory diseases such as arthritis and joint pain.

Astaxanthin can absorb blue light and protect the retina from light damage, which helps prevent the occurrence of eye diseases such as macular degeneration and cataracts. Astaxanthin can accumulate in the retina, like a “natural filter”, absorbing harmful blue light, while removing free radicals and protecting photoreceptor cells.

Astaxanthin’s diverse applications

Health care products: a healthy and caring partner​

Astaxanthin has significant effects in health care products. It can strengthen the immune system and enhance the body’s ability to resist diseases. For people who are often prone to colds and illnesses, an appropriate amount of astaxanthin supplementation can stimulate the activity of immune cells, increase the number of immune cells, thereby improving the body’s resistance and reducing the number of illnesses. In terms of anti-cancer, astaxanthin also plays a positive role.

Astaxanthin can absorb blue light and reduce its damage to the retina. At the same time, it can also remove free radicals in the retina and prevent the occurrence of eye diseases such as macular degeneration and retinopathy. For office workers, students, and middle-aged and elderly people who use electronic devices for a long time, supplementing astaxanthin can help protect eye health and maintain good vision. ​

Astaxanthin can inhibit the release of inflammatory mediators and reduce inflammatory reactions. It is very helpful for relieving the symptoms of inflammatory diseases such as arthritis and gout. After taking astaxanthin health care products, some arthritis patients have significantly improved symptoms such as joint pain and swelling, and the range of motion of the joints has also improved, and the quality of life has been improved. ​

Cosmetics: The secret to youthful skin​

In the field of cosmetics, astaxanthin’s antioxidant, anti-wrinkle, whitening and moisturizing properties make it a “favorite” of many cosmetic brands. ​

From the perspective of antioxidant, astaxanthin’s powerful antioxidant ability can effectively remove free radicals in skin cells. The conjugated double bonds and unique structure in astaxanthin molecules enable it to capture and neutralize free radicals like a “scavenger”, reduce the damage of free radicals to the skin, and thus delay skin aging. ​

In terms of anti-wrinkle, astaxanthin can promote the synthesis of collagen. Astaxanthin can stimulate fibroblasts in skin cells to produce more collagen, increase the elasticity and firmness of the skin, and reduce the formation of wrinkles. ​

In terms of whitening skin, astaxanthin inhibits the formation of melanin. Astaxanthin can inhibit the activity of tyrosinase, which is a key enzyme in the synthesis of melanin, thereby reducing the production of melanin and making the skin whiter.

In terms of moisturizing, astaxanthin can increase the moisture content of the skin. It can regulate the water channel protein in the skin, promote the transport and retention of water between skin cells, and keep the skin hydrated. At the same time, astaxanthin can also enhance the barrier function of the skin, reduce the loss of water, and keep the skin moist at all times. ​

Based on these magical effects, there are many types of cosmetics containing astaxanthin. Adding astaxanthin to sunscreen products can not only block the damage of ultraviolet rays to the skin, but also play an antioxidant role inside the skin, reduce the free radical damage caused by ultraviolet rays, and prevent sun spots, sunburn and other problems. Adding astaxanthin to skin care products such as lotions, creams, and essences can deeply nourish the skin, improve skin dryness, roughness, dullness and other problems, and make the skin glow with a healthy glow. ​

Food: Fusion of deliciousness and nutrition​

In the food field, astaxanthin plays a dual role, both as a colorant and a preservative, bringing a perfect fusion of deliciousness and nutrition to food. ​

As a colorant, astaxanthin can make food appear bright red. Astaxanthin is also an excellent preservative, which can extend the shelf life of food. Astaxanthin’s strong antioxidant ability can inhibit the oxidation of oils and maintain the freshness and flavor of food. Astaxanthin is widely used in food. In addition to the above-mentioned meat products, baked goods and beverages, it is also used in foods such as noodles and seasonings. ​

In food applications, the safety of astaxanthin is a matter of great concern. At present, astaxanthin has been widely recognized and applied as a food additive. Relevant studies have shown that astaxanthin is safe and harmless to the human body within the prescribed range of use.

However, it should be noted that the amount of astaxanthin added should comply with relevant national standards, and excessive addition may affect the taste and quality of food. At the same time, when storing and using astaxanthin, care should be taken to avoid factors such as high temperature and light, so as not to cause oxidation and degradation of astaxanthin, affecting its efficacy and stability.

Aquaculture: the source of vitality for aquaculture​

In the field of aquaculture, astaxanthin plays a vital role in the bright color and healthy growth of aquatic animals. It can be called the source of vitality of aquatic products. ​

For crustaceans such as shrimps and crabs, astaxanthin is the key factor in their bright body color. In the natural environment, shrimps and crabs accumulate astaxanthin in their bodies by consuming astaxanthin-rich foods, thus showing beautiful red or orange colors. During the breeding process, if there is a lack of astaxanthin in the feed, the body color of shrimps and crabs will become dull, affecting their market value.

In fish farming, astaxanthin is also indispensable. Taking salmon as an example, astaxanthin can not only make the meat of salmon present an attractive orange-red color, but also improve the deliciousness and nutritional value of its meat. Astaxanthin can also enhance the immunity of fish, reduce the occurrence of diseases, and improve the survival rate of breeding. ​

The dosage of astaxanthin needs to be reasonably controlled according to the type, growth stage and breeding environment of aquatic animals. Reasonable control of the dosage of astaxanthin can not only ensure that aquatic animals get enough nutrition, but also avoid the cost increase and potential risks caused by excessive addition. ​

The addition of astaxanthin has a significant effect on improving the economic benefits and quality of aquaculture. By adding astaxanthin, the body color of aquatic animals is brighter, the meat is more delicious, and the market value is greatly improved.

Astaxanthin can also improve the immunity and anti-stress ability of aquatic animals, reduce the occurrence of diseases, and reduce breeding costs, thereby bringing higher economic benefits to farmers. In today’s market environment where consumers have higher and higher requirements for the quality of aquatic products, the application prospects of astaxanthin in aquaculture will be broader.

Suitable for People Taking Astaxanthin

Astaxanthin has many health benefits. The following are some people who are suitable for taking astaxanthin:

Middle-aged and elderly people: Astaxanthin’s powerful antioxidant capacity can help reduce the damage of free radicals to cells, prevent cardiovascular diseases, Alzheimer’s disease, cataracts and other age-related diseases, and improve skin conditions, reduce wrinkles and spots.

People who face electronic devices for a long time: Astaxanthin can cross the blood-eye barrier, protect the retina and macula of the eyes, prevent retinopathy and macular degeneration, and relieve visual fatigue.

Sports enthusiasts: Astaxanthin helps to reduce oxidative stress, promote muscle recovery, improve sports endurance, reduce fatigue and inflammatory response after exercise, help sports enthusiasts recover from training faster, and improve sports performance.

People with low immunity: Astaxanthin can regulate the immune system, enhance the activity of immune cells, improve the body’s resistance, and help people with low immunity better resist the invasion of pathogens such as bacteria and viruses, and prevent colds and other diseases.

People with poor skin condition: Astaxanthin can inhibit the production of melanin, reduce spots and wrinkles, increase skin elasticity and luster, and has certain whitening and anti-wrinkle effects. It is suitable for people with dry skin, wrinkles, spots and other problems.

People at high risk of cardiovascular disease: Astaxanthin helps lower blood lipids and blood pressure, inhibit platelet aggregation, reduce the risk of atherosclerosis, and has a protective effect on the cardiovascular system.

However, for pregnant women, breastfeeding women, and people who are taking certain medications, it is recommended to consult a doctor before using astaxanthin to ensure safety and effectiveness.

Correct Understanding and Use of Astaxanthin

Although astaxanthin has many benefits, we must be clear that it can never replace normal medical treatment and a healthy lifestyle.

There are many key points to note when it comes to the reasonable intake of astaxanthin. Generally speaking, ordinary people can meet basic antioxidant needs by consuming 4-8mg of astaxanthin per day. However, for people with special needs, such as athletes and heavy manual laborers, the intake can be increased to 8-12mg to improve fatigue resistance.

For patients with diabetes and hyperlipidemia, the intake can be further increased to 10-15mg to improve blood sugar and blood lipid metabolism. Astaxanthin is a fat-soluble substance. It is recommended to take it with meals or within half an hour after meals. At this time, more lipids are consumed, which is more conducive to the emulsification and absorption of astaxanthin.

There is also a view that it is better to take it after meals at night to ensure better absorption. When taking astaxanthin for the first time, it is recommended to start with a lower dose, such as 1 capsule each time, and then gradually increase the dose after observing the body’s reaction. ​

It is crucial to choose a regular product. When buying astaxanthin products, be careful to identify them. Check whether the product has a test report from an authoritative organization to ensure its authenticity. Give priority to big brands with complete production qualifications and transparent product information.

Astaxanthin itself is not very stable and is easily oxidized and decomposed when exposed to light. Therefore, when storing astaxanthin products, choose light-proof and well-sealed packaging and place them in a cool and dry place. Avoid exposing astaxanthin products to direct sunlight and high temperatures for a long time, and do not expose them to the air.

When taking astaxanthin, be careful to avoid exposing it to light for a long time and dispose of it quickly. Astaxanthin may interact with certain drugs, such as lipid-lowering drugs and anticoagulants. If you are taking these drugs, you should consult a doctor before taking astaxanthin.

People who are allergic to astaxanthin should avoid using it to avoid allergic reactions. Pregnant women, breastfeeding women, and patients undergoing anticoagulant treatment should avoid using astaxanthin, or use it with caution under the guidance of a doctor.

The Future of Astaxanthin​

As a substance with excellent properties and wide application value, astaxanthin has played an important role in many fields in the past few decades, and its future development prospects are full of unlimited possibilities.

In terms of source exploration, although natural extraction and artificial synthesis are currently the main ways, researchers will continue to explore new biological sources in the future. In the field of artificial synthesis, the development of new synthesis processes and catalysts will make the synthesis process greener and more efficient, reduce production costs, and improve product purity. ​

In terms of efficacy research, astaxanthin will make breakthroughs in the prevention and auxiliary treatment of more diseases. With the in-depth study of its mechanism of action, astaxanthin may show unique therapeutic effects in the fields of nervous system diseases and metabolic diseases.

In terms of application expansion, astaxanthin will be more widely used in the agricultural field. It can be used as a biostimulant to promote plant growth and development and improve plant stress resistance. ​

Urolithin A, also known as Urolithin A in English, or UA for short, has nothing to do with stones. It is neither a substance synthesized directly by the human body nor a nutrient that can be directly obtained from food, but a unique metabolite of intestinal microorganisms. ​

The formation process of urolithin A is quite complicated. Tracing back to its source, the source of urolithin A is ellagitannins in food. Ellagitannins are widely found in nature, such as fruits and nuts such as pomegranates, blueberries, strawberries, raspberries, walnuts, and some wines aged in oak barrels.

When we consume these foods containing ellagitannins, they will first be hydrolyzed in the intestines to release ellagic acid. However, ellagic acid cannot be directly absorbed and utilized by the human body. At this time, the intestinal flora begins to play a key role. They will further process and transform ellagic acid and eventually produce urolithin A.

The Amazing Effects of Urolithin A​

Although urolithin A cannot be obtained directly from food, it plays many wonderful roles in human health, like an “invisible guard” that silently protects human health.

The guardian of muscle health

As people age, muscle loss is a problem that many people have to face, especially the elderly. The reduction in muscle mass will not only lead to weakened physical strength, but also affect daily activities and reduce the quality of life.

Fortunately, urolithin A has shown significant effects in improving muscle loss. Data show that urolithin A supplements can effectively enhance the muscle endurance of skeletal muscles in the elderly and have a positive effect on alleviating muscle atrophy in the elderly.

However, in terms of improving athletic ability, such as 6-minute walking distance and hand muscle ATP production, the effect of urolithin A is not very ideal.

In the long run, the benefits of supplementing urolithin A on muscle loss are still relatively obvious. It is like a loyal guardian, helping the elderly to resist muscle decline, especially muscle loss caused by aging.

For fitness enthusiasts, urolithin A may also be their good helper. Although there is no conclusive evidence that it can significantly enhance the effect of exercise, judging from its role in resisting muscle atrophy, perhaps in the long-term fitness process, urolithin A can help maintain muscle mass and endurance, allowing fitness enthusiasts to go one step further in their pursuit of health and strength. ​​

A booster for weight loss

Urolithin A can affect cellular lipid metabolism and fat. Studies have found that urolithin A can reduce triglyceride accumulation and fatty acid oxidation, as well as reduce the expression of genes related to lipogenesis. As we all know, brown fat is a “special member” of the fat family.

Not only does it not make people fat, but it can burn fat and provide energy for the body. Therefore, the more brown fat, the more conducive to weight loss. Urolithin A plays a positive role in the weight loss process in this unique way, just like a caring partner, helping dieters to better manage their weight and move towards their ideal body shape. ​

Activators of mitophagy

Mitochondria, a tiny organelle known as the “power plant” of cells, plays a vital role in the life activities of cells. It generates ATP through the electron transport chain to provide energy for cells. However, in the process of energy generation, reactive oxygen species (ROS) are generated.

These ROS are like “troublemakers” that damage proteins, fatty acids and nucleic acids, trigger a chain reaction of peroxidation, and cause damage to cells. Mitochondrial autophagy is like a “cleaning guard” in cells. It can selectively remove damaged mitochondria through autophagosomes and maintain the healthy homeostasis of mitochondria in cells.

With the increase of age and the emergence of some age-related diseases, the ability of mitochondrial autophagy will gradually decrease or even stagnate, which is like the accumulation of garbage when the cleaning work is not in place, which will slowly lead to the decline of organ function.

The magic of urolithin A is that it can activate mitochondrial autophagy through multiple pathways. On the one hand, urolithin A can activate enzymes that promote mitochondrial autophagy and accelerate the process of mitochondrial autophagy.

On the other hand, it can also regulate the mitochondrial autophagy pathway, ensure that all aspects of mitochondrial autophagy can proceed in an orderly manner, and promote the formation of autophagosomes, providing the necessary conditions for the smooth development of mitochondrial autophagy.

Through these effects, urolithin A effectively reduces the production of ROS, prevents mitochondrial DNA damage and mutation, maintains the health of mitochondria, and thus delays the decline of organ function, allowing the various organs of the body to maintain a good working condition, just like a well-maintained machine, running continuously and efficiently. ​

The “killer” of inflammation​

Inflammation, this invisible “enemy”, often causes damage to our body silently. Urolithin A is like a brave warrior, fighting fiercely against inflammation. Scientists first discovered the anti-inflammatory effect of urolithin A in rat enteritis experiments.

As the research continues to deepen, people have found that urolithin A also has different degrees of reduction effects on other inflammatory markers, such as proinflammatory factors and tumor necrosis factor. Since urolithin A is present in large quantities in the intestine, it has a significant anti-inflammatory effect on inflammatory bowel disease, including acute enteritis, ulcerative colitis, and even colon cancer.

The anti-inflammatory ability of urolithin A is more than that, because it can reduce the overall serum level of inflammatory factors, so in theory, it can play a certain role in all diseases caused by inflammation. For example, common joint diseases such as arthritis and intervertebral disc degeneration in the elderly. In addition, inflammatory damage to nerves is the root cause of many neurodegenerative diseases.

When urolithin A exerts its anti-inflammatory effect in the brain, it can improve many neurodegenerative diseases, such as Alzheimer’s disease, memory impairment and stroke, providing new ideas and methods for the treatment and prevention of these diseases.

Improvers of metabolic diseases​

Urolithin A plays an important role in improving metabolic diseases with its unique biological effects. As mentioned earlier, urolithin A has anti-inflammatory and mitochondrial autophagy activation effects. These two effects are like two “sharp blades” that can effectively alleviate the symptoms of metabolic diseases.

In addition, urolithin A has a powerful ability, which is to improve oxidative stress. It can be like a hardworking “cleaner” to remove free radicals produced in the body and reduce the oxidative damage of free radicals to cells. It can also inhibit the activity of oxidases and reduce the occurrence of oxidative reactions from the source. It can also enhance the antioxidant capacity of cells and provide cells with a stable internal environment so that cells can carry out metabolic activities normally.

In terms of improving hyperglycemia, ellagic acid in pomegranates and tea leaves rich in polyphenols has anti-diabetic effects, and ellagic acid is metabolized into urolithin under the action of intestinal flora, which also has multiple biological activities and plays a certain role in regulating blood sugar.

In terms of improving atherosclerosis, urolithin A reduces the risk of atherosclerosis and protects the health of the cardiovascular system through anti-inflammatory, anti-oxidative stress and inhibition of cholesterol accumulation.

In terms of improving metabolic disorder-related fatty liver disease, urolithin A has a significant improvement effect on non-alcoholic fatty liver disease. It can inhibit fat synthesis, promote the conversion of white fat to beige fat, improve dyslipidemia and hepatic steatosis in obese animals, and promote heat production and improve obesity by increasing the content of triiodothyronine (T3) in brown fat and white adipose tissue, thereby effectively alleviating the symptoms of fatty liver disease. ​

How to Get Urolithin A?​

Since urolithin A has so many benefits for human health, how can we obtain it? We need to provide the body with precursors for synthesizing urolithin A by consuming foods containing ellagitannins. ​

Pomegranates are a “rich mine” of ellagitannins. The content of ellagitannins in every 100 grams of pomegranates can be as high as 100-300 mg. Whether it is eaten directly or squeezed into juice, it is a good choice. Blueberries are also one of the fruits rich in ellagitannins. Small and round blueberries have a deep color.

The content of ellagitannins in every 100 grams of blueberries is about 50-150 mg. Strawberries, a popular fruit, are not only delicious, but also contain a certain amount of ellagitannins.

The content of ellagitannins in every 100 grams of strawberries is about 30-80 mg. There are also raspberries, a unique-looking berry with an ellagitannin content of about 40-120 mg per 100 g. It can be eaten directly or used to make various drinks. ​

Among the nut family, walnuts are also a good source of ellagitannins. The content of ellagitannins in 100 g of walnuts is about 60-180 mg. In addition to the above common foods, some wines aged in oak barrels also contain ellagitannins. While tasting wine, you may also inadvertently bring some benefits to the body.

However, even if we consume enough foods rich in ellagitannins, it does not necessarily guarantee that the body can synthesize enough urolithin A. This is because the synthesis of urolithin A is also affected by the intestinal flora. Everyone’s intestinal flora is unique, just like our fingerprints.

Different intestinal flora compositions have different abilities to convert ellagic acid into urolithin A. Related research shows that only about 40% of people can naturally convert urolithin A from precursors to usable urolithin A.

This also explains why some people eat a lot of foods rich in ellagitannins but still have low levels of urolithin A in their bodies. ​

People Who Are Suitable for Taking Urolithin A

Middle-aged and elderly people: Middle-aged and elderly people are prone to problems such as reduced muscle mass, decreased muscle function, and mitochondrial function decline.

Urolithin A can activate mitochondrial autophagy, help maintain the normal function of mitochondria in cells, slow down cell aging, and then alleviate muscle atrophy to a certain extent, enhance muscle endurance, and may help prevent and improve osteoporosis and mobility problems common in middle-aged and elderly people.

Sports people: including athletes, fitness enthusiasts, etc. Urolithin A can enhance muscle function, help sports people recover muscle strength and endurance faster after training, reduce muscle fatigue and injury, improve sports performance, help them better perform high-intensity training and competition, promote physical recovery after exercise, and improve overall athletic ability.

Health-conscious people: Urolithin A is attractive to those who pay attention to health and hope to maintain physical function and prevent chronic diseases through diet or nutritional supplements. It has potential anti-inflammatory, antioxidant and metabolic regulation effects, which can help maintain the stability of the body’s internal environment, reduce the risk of some chronic diseases, and help maintain overall health.

People with certain chronic diseases: such as those with chronic diseases such as cardiovascular disease and neurodegenerative diseases. Studies have found that the effects of urolithin A in anti-inflammation, cell protection, and improved mitochondrial function may help alleviate the symptoms of these diseases, delay the progression of the disease, and have certain positive significance for the auxiliary treatment and recovery of the disease.

However, despite the many potential benefits of urolithin A, everyone’s physical condition and response to nutrients are different. Before considering the use of urolithin A supplements, especially those with specific diseases or taking other medications, it is best to consult a doctor or professional nutritionist to ensure safety and effectiveness.

Current Status and Future of Urolithin A​

In recent years, research on urolithin A has sprung up, and its research results in improving neurodegenerative diseases such as Alzheimer’s disease are particularly eye-catching. However, there are still many limitations and uncertainties in the current research on urolithin A.

In terms of research methods, most experiments are conducted in cell models or animal models. Although these experiments can provide us with certain theoretical basis, there are still large differences from the actual situation of the human body.

Moreover, the sample size of the experiment is relatively small, which affects the universality and reliability of the research results to a certain extent.

From the perspective of the mechanism of action, although we already know that urolithin A can play a role by activating mitochondrial autophagy and other pathways, the specific molecular mechanism still needs further in-depth study. In addition, the impact of individual differences on the effect of urolithin A cannot be ignored.

There are differences in the composition and metabolic capacity of the intestinal flora of different people, and these differences may lead to very different metabolism and effects of urolithin A in different individuals.

Despite these problems, the application prospects of urolithin A in the fields of medical care and health care are still very broad. In the medical field, urolithin A may become a new drug or auxiliary treatment for the treatment of various diseases. In the field of health care, urolithin A also has great potential.

As people’s health awareness continues to improve, the demand for health products is also increasing. It can help people increase muscle strength, improve metabolic function, delay aging, etc., so that people can better maintain a healthy state in daily life.

In the future, with the continuous advancement of science and technology and the continuous deepening of research, we have reason to believe that there will be more breakthroughs in the research on urolithin A.

Scientists may further reveal the mechanism of action of urolithin A, optimize its preparation process, increase its yield and purity, and reduce production costs, so that it can be more widely used in the medical and healthcare fields.

Apigenin contains a wealth of health codes and has a positive impact on many physiological processes of the human body. Whether it is cardiovascular health, immune regulation, or potential anti-cancer effects, apigenin has shown remarkable effects, attracting countless scientific researchers to conduct in-depth research, and also making people who pay attention to health full of expectations for it.

So, what exactly is apigenin? Where does it come from? What kind of magical effects does it have? Next, let us explore the world of apigenin in depth and unveil its mysterious veil.​

Basic Information About Apigenin​

Chemical Structure​

Apigenin, also known as apigenin or apigenin, has a unique structure that gives it many special chemical properties and biological activities. In its structure, hydroxyl groups are connected to the 5, 7, and 4′ positions, respectively. The presence of these hydroxyl groups plays a key role in the antioxidant and anti-inflammatory activities of apigenin.

For example, they can provide hydrogen atoms to remove free radicals in the body, thereby exerting antioxidant effects. At the same time, this structure also determines the active site of apigenin in chemical reactions, enabling it to interact with other biological molecules and thus affect the physiological functions of cells. ​

Physical Properties​

Pure apigenin usually appears as a yellow crystalline powder with bright color, odorless and tasteless. It is a natural antioxidant. Its melting point is high, reaching 345-350°C, which indicates that it has a relatively stable molecular structure and can remain solid under normal temperature conditions. ​

In terms of solubility, apigenin exhibits typical fat-soluble characteristics and is almost insoluble in water. This is because most of its molecular structure is a non-polar carbon-hydrogen skeleton, and the interaction force between it and polar water molecules is weak.

However, it is partially soluble in hot alcohol. This is because the polarity of alcohol is relatively moderate and has a certain lipophilicity, which can form a certain interaction with apigenin molecules, so that apigenin has a certain solubility in hot alcohol.

In addition, apigenin can also be dissolved in dilute KOH solution. This is because under alkaline conditions, the hydroxyl groups in the apigenin molecules can react with the base to form water-soluble salts, thereby increasing its solubility in the solution.​

Nature’s “Apigenin Treasure”

Common Plant Sources​

Apigenin is widely found in many plants, and nature seems to be a natural “treasure trove of apigenin”. Celery, as the vegetable with the highest apigenin content, deserves to be the main channel for people to obtain apigenin. In addition to celery, chamomile is also one of the high-quality sources of apigenin.

It not only has a unique aroma, but also contains a large amount of apigenin. It is often used to make tea and is deeply loved by people. Broccoli, onions and other vegetables also contain a certain amount of apigenin, which protects people’s health.

In the world of fruits, common fruits such as apples and oranges also contain apigenin. These fruits are delicious and easy to eat, allowing people to enjoy delicious food while also taking in apigenin that is beneficial to health.

These vegetables and fruits, with their rich apigenin content, have become an indispensable part of people’s daily diet and provide natural support for human health. ​

Distribution Pattern​

In the plant kingdom, the distribution of apigenin shows a certain pattern. It is mainly found in plant groups such as Thymelaeaceae, Verbenaceae, and Selaginellaceae. There are also obvious differences in the content of apigenin in different plant parts.

Generally speaking, the content of apigenin in leaves and flowers of plants is relatively high. In contrast, the content of apigenin in roots, stems and other parts of plants is relatively low. This distribution pattern is closely related to the physiological functions and growth needs of plants, reflecting the wonder and wisdom of nature.​

Amazing Health Benefits

Antioxidant Pioneer​

During the metabolism of the human body, free radicals are constantly generated, such as superoxide anion free radicals and hydroxyl free radicals. These free radicals are highly active and will attack biological macromolecules in cells, such as DNA, proteins and lipids, leading to oxidative damage, and then causing various diseases, such as cardiovascular disease, cancer, neurodegenerative diseases, etc.

As a natural antioxidant, apigenin can effectively remove these free radicals and protect cells from oxidative damage. Its antioxidant effect is mainly achieved in the following ways. ​

Multiple hydroxyl groups in the molecular structure of apigenin, such as the hydroxyl groups at the 4′, 5, and 7 positions, can provide hydrogen atoms, combine with free radicals, and convert them into stable products, thereby removing free radicals.

Apigenin can also enhance the antioxidant defense ability of cells by activating the antioxidant enzyme system in cells. Apigenin can upregulate the gene expression of these antioxidant enzymes, increase their activity, and enable cells to better cope with oxidative stress.

In addition, apigenin also has metal ion chelation. In the body, some transition metal ions, such as iron ions and copper ions, can catalyze the production of free radicals, such as catalyzing hydrogen peroxide to produce highly active hydroxyl radicals through the Fenton reaction.

Apigenin can bind to these metal ions to form stable chelates, reduce the activity of metal ions, and thus inhibit the production of free radicals.

In an in vitro chemical simulation system, the addition of apigenin can effectively inhibit the hydroxyl radicals produced by the Fenton reaction and reduce the oxidative damage of free radicals to biological molecules. This shows that the metal ion chelation of apigenin plays an important role in the antioxidant process. ​

The Patron Saint of Cardiovascular System​

With the improvement of living standards and changes in lifestyle, cardiovascular disease has become one of the main diseases threatening human health.

The incidence of cardiovascular diseases such as hypertension, hyperlipidemia, and atherosclerosis has increased year by year, bringing a huge burden to people’s health. Apigenin plays a significant role in maintaining cardiovascular health and is known as the “guardian” of cardiovascular. ​

The increase in blood pressure is closely related to the contraction and relaxation of blood vessels. Apigenin has the effect of vasodilation, which can promote the relaxation of vascular smooth muscle, reduce peripheral vascular resistance, and thus lower blood pressure.

Hyperlipidemia is one of the important risk factors for cardiovascular disease, which is mainly manifested in increased levels of cholesterol, triglycerides and low-density lipoprotein (LDL) in the blood, and decreased levels of high-density lipoprotein (HDL).

Apigenin can regulate blood lipid metabolism through various pathways. It can inhibit the synthesis of fatty acids and cholesterol in the liver and reduce the production of lipids. Apigenin can also promote lipid catabolism, increase the oxidation of fatty acids, and reduce the content of lipids in the blood.

Apigenin can also regulate the activity of lipoprotein metabolism-related enzymes, such as lipoprotein lipase (LPL) and hepatic lipase (HL), promote the clearance of LDL, increase the level of HDL, and thus improve blood lipid status.

Atherosclerosis is the pathological basis of cardiovascular disease, and its occurrence is closely related to factors such as abnormal proliferation of vascular smooth muscle cells, inflammatory response, and lipid deposition.

Apigenin can inhibit the proliferation of vascular smooth muscle cells and prevent the thickening of vascular walls. Apigenin also has anti-inflammatory effects, which can inhibit the activation of inflammatory cells and the release of inflammatory mediators, and reduce the inflammatory response of the vascular wall.

In addition, apigenin can prevent the oxidative modification of low-density lipoprotein and reduce the damage of oxidized low-density lipoprotein (ox-LDL) to vascular endothelial cells, thereby inhibiting the occurrence and development of atherosclerosis.​

The Secret Weapon Against Tumors

Cancer has always been a major disease that threatens human life and health, and has brought heavy pain to countless patients and families.

For many years, researchers have been tirelessly exploring various effective anti-cancer methods and drugs, and apigenin, as a natural plant ingredient, has shown great potential in the field of anti-tumor and has become the focus of attention. ​

A large number of studies have shown that apigenin can inhibit the growth of a variety of tumor cells, including breast cancer, gastric cancer, prostate cancer, lung cancer, etc.

It can achieve this effect through a variety of mechanisms. Apigenin can interfere with the signal transduction pathways of tumor cells and affect cell proliferation, differentiation and apoptosis.

Inducing tumor cell apoptosis is one of the important mechanisms of apigenin’s anti-tumor effect. When cells become cancerous, the apoptosis mechanism is often inhibited, resulting in unlimited proliferation of cancer cells. Apigenin can activate the apoptosis signaling pathway in tumor cells and induce apoptosis of cancer cells.

Tumor metastasis is a major problem in cancer treatment and one of the main reasons for poor prognosis in patients. Apigenin also plays an important role in inhibiting tumor metastasis. It can inhibit the migration and invasion of tumor cells and reduce the spread of tumor cells to surrounding tissues and distant organs. ​

In addition to the above-mentioned mechanisms of action, apigenin can also inhibit tumor growth and development by inhibiting tumor angiogenesis and cutting off the nutrient supply of tumor cells.

Tumor growth and metastasis depend on the formation of new blood vessels to provide oxygen and nutrients to tumor cells. Apigenin can inhibit the expression and activity of vascular endothelial growth factor (VEGF) and its receptors, prevent the proliferation, migration and lumen formation of vascular endothelial cells, and thus inhibit tumor angiogenesis.​

Antibacterial and Antiviral Expert​

In daily life, we are often invaded by various bacteria, fungi and viruses. Infectious diseases caused by these pathogens pose many threats to our health. Apigenin, with its unique antibacterial and antiviral properties, has shown important application prospects in the field of anti-infection and has become another guardian of our health. ​

Many studies have shown that apigenin has a significant inhibitory effect on common bacteria. For Gram-positive bacteria, such as Staphylococcus aureus and Bacillus subtilis, apigenin can destroy their cell wall structure, making the cell wall fragile, causing cell contents to leak, thereby inhibiting bacterial growth.

Although apigenin has a relatively weak inhibitory effect on Gram-negative bacteria, it can still effectively inhibit the growth and reproduction of these bacteria at a certain concentration. ​

In addition to bacteria, apigenin also has an inhibitory effect on some fungi. Candida albicans is a common pathogenic fungus that is prone to infection in the skin, mucous membranes and other parts. Apigenin can inhibit the growth and reproduction of Candida albicans by interfering with its cell membrane function and intracellular signal transduction pathways.

In terms of antiviral, apigenin also shows certain potential. Studies have found that apigenin has an inhibitory effect on influenza virus, herpes simplex virus, etc.

It can prevent viral infection and spread by inhibiting the adsorption, invasion, and replication of the virus. Apigenin can also interfere with the replication process of the virus in the cell, inhibit the synthesis of viral proteins, and reduce the production of the virus. ​

Other Health Benefits​

In the fast-paced modern life, people are facing various pressures, prone to anxiety, insomnia and other problems, and memory may also be affected. The efficacy of apigenin in calming the mind, improving sleep and improving memory provides new hope for people to alleviate these troubles. ​

Apigenin can regulate the function of the nervous system and inhibit the excessive excitement of nerve cells, so that people can feel relaxed and peaceful. For those who are in a state of tension for a long time and are prone to anxiety, consuming foods rich in apigenin or supplementing apigenin may help relieve anxiety and relax the body and mind. ​

Good sleep is one of the important factors in maintaining physical health, however, insomnia troubles many people. Apigenin has a certain effect on improving sleep.

Apigenin can regulate the expression of genes related to the biological clock, help people adjust their sleep rhythm, and make sleep more regular. For insomnia patients, appropriate intake of apigenin may be a safe and natural way to improve sleep. ​

With the increase of age, people’s memory tends to gradually decline, which brings many inconveniences to daily life. The role of apigenin in improving memory has also attracted the attention of researchers.

Studies have shown that apigenin can promote the growth and differentiation of nerve cells and strengthen the connection between nerve cells, thereby improving memory. It can also protect nerve cells from damage and maintain the normal function of nerve cells through antioxidant and anti-inflammatory effects.

The Exploration of Extraction and Synthesis

Natural Extraction Method​

In the exploration of apigenin extraction, researchers have been trying various methods, and solvent extraction, macroporous resin purification, supercritical CO2 fluid method, etc. have become the main research directions.

Solvent extraction is a relatively traditional and widely used method. It uses organic solvents to extract apigenin based on the principle of like dissolves like. However, this method also has some obvious disadvantages.

Since a large amount of organic solvents are used in the extraction process, it will not only cause solvent residue problems, affect the quality and safety of the product, but also cause environmental pollution.

The purity of apigenin obtained by this method is relatively low, and often cannot meet the needs of medicine, food and other fields with high purity requirements. ​

Macroporous resin purification method uses the adsorption and desorption characteristics of macroporous resin on apigenin to achieve the separation and purification of apigenin. Macroporous resin has a large specific surface area and pore size, and can selectively adsorb flavonoid compounds such as apigenin.

The advantage of macroporous resin purification method is that it can effectively improve the purity of apigenin, and the operation is relatively simple and the cost is low. This method also has some shortcomings, such as relatively low yield and is not suitable for large-scale industrial production. ​

Supercritical CO2 fluid method is a relatively new extraction technology that uses the special properties of supercritical CO2 fluid to extract apigenin. In the supercritical state, CO2 fluid has good solubility for apigenin.

When the pressure or temperature changes, its solubility for apigenin will also change, thereby achieving the extraction and separation of apigenin. The supercritical CO2 fluid method has many advantages, such as low operating temperature, which can better protect the active ingredients of apigenin from being destroyed.

No organic solvent is used in the extraction process, avoiding solvent residue and environmental pollution problems. The extraction efficiency is high, and apigenin can be quickly extracted from the raw material. This method also has some limitations, such as large equipment investment, high operating costs, and strict technical requirements.

Semisynthesis and Biosynthesis​

In addition to extracting apigenin from natural plants, semi-synthetic and biosynthetic methods also provide new ways to obtain apigenin. ​

The semi-synthetic method usually uses natural extracts as raw materials to synthesize apigenin through chemical reactions. This method is relatively simple to operate, the reaction conditions are relatively stable, easy to control, and the product is easy to separate and purify.

The total yield of the product can reach 60%-70%, and the purity can reach more than 97%. However, this method also has some disadvantages, such as the use of 1,4-dioxane, which is highly toxic and expensive, and is easy to cause environmental pollution and lead to high production costs.

The crude apigenin generated by oxidative dehydrogenation needs to go through complex processing steps, which are cumbersome and time-consuming. ​

The biosynthetic method uses enzymes or microorganisms in organisms to synthesize apigenin. It has the advantages of being green, pollution-free, economical, and efficient. It is an important development direction for the synthesis of apigenin.

The biosynthetic method can also use plant cell culture technology to culture plant cells in vitro, and by regulating the culture conditions, the cells can synthesize apigenin. Although the biosynthesis method has many advantages, it is still in the research stage and there are some technical problems to be solved, such as low synthesis efficiency and high production cost.

However, with the continuous development and innovation of biotechnology, it is believed that the biosynthesis method is expected to become an important method for apigenin production in the future. ​

Curcumin is a chemical component extracted from the rhizomes of some plants in the Zingiberaceae and Araceae families. It is a rare pigment with a diketone structure in the plant kingdom and belongs to the diketone class of compounds. This structure gives curcumin many special properties and biological activities.

In terms of appearance, curcumin is an orange-yellow crystalline powder with a slightly bitter taste. It is insoluble in water and ether, but soluble in ethanol and propylene glycol, and easily soluble in glacial acetic acid and alkaline solutions. It is reddish brown in alkaline environments and yellow in neutral and acidic environments.

It has strong stability to reducing agents and strong coloring properties. Once colored, it is not easy to fade, but it is very sensitive to light, heat, and iron ions, and has poor light resistance, heat resistance, and iron ion resistance.

Curcumin will undergo a conjugation effect of electron cloud deviation under alkaline conditions. When the pH value is greater than 8, curcumin will change from yellow to red. Modern chemistry also uses this property to use it as an acid-base indicator. ​

Extraction Method of Curcumin​

As people’s research on curcumin deepens, its extraction methods are also constantly developing and innovating. Different extraction methods have their own characteristics. From traditional processes to modern auxiliary technologies, they all provide the possibility of obtaining high-purity and high-yield curcumin.

Traditional Extraction Method​

Solvent extraction is a more traditional curcumin extraction process. It uses the principle of like dissolves like and realizes extraction based on the difference in solubility of curcumin in different solvents.

Commonly used extraction media include ethanol, methanol, alkaline water, etc. These solvents can dissolve curcumin well, thereby separating it from plant raw materials.

In actual operation, decoction and reflux methods are more commonly used. Decoction method is to heat and boil the turmeric raw material and solvent together to make curcumin fully dissolved in the solvent.

This method is relatively simple to operate and does not require high equipment, but the extraction time is long, and part of the curcumin may be decomposed due to high temperature, affecting the extraction efficiency and quality.

The reflux method is to use a reflux device to circulate the solvent continuously during the heating process to continuously extract curcumin. It can improve the utilization rate of the solvent, reduce the volatile loss of the solvent, and improve the extraction efficiency to a certain extent. However, this method also has problems such as high energy consumption and relatively cumbersome operation.

The traditional extraction process is relatively mature and widely used, but it also has shortcomings such as high solvent consumption, long extraction time, and easy loss of effective ingredients, which also prompts people to continuously explore new extraction technologies. ​

Modern Assisted Extraction​

In order to overcome the shortcomings of traditional extraction methods, modern auxiliary extraction technology has emerged, and ultrasonic-assisted extraction is one of them. Ultrasonic-assisted extraction is to add ultrasonic assistance while water extraction.

Ultrasonic waves can generate high-frequency vibrations and form a strong cavitation effect. When extracting curcumin, this cavitation effect can quickly rupture plant cells, making curcumin easier to dissolve, thereby increasing the extraction rate.

Moreover, this method does not require high temperature, avoiding the destruction of curcumin’s effective ingredients by high temperature, and retaining the biological activity of curcumin to the greatest extent. Compared with traditional extraction methods, a higher extraction rate is achieved in a shorter time. ​

Microwave-assisted extraction also has unique advantages. It adds microwaves while water extraction. The thermal and non-thermal effects of microwaves can make the polar molecules in plant cells vibrate rapidly, generate internal heat, promote cell rupture, and accelerate the dissolution rate of curcumin.

Compared with traditional water extraction, microwave-assisted extraction has the characteristics of high selectivity, short operation time, low solvent consumption, and high yield of effective ingredients. Microwave-assisted extraction has significant advantages in improving extraction efficiency and effective ingredient yield. ​​

Efficacy and Function of Curcumin​

Curcumin has a wide range of effects and functions. It exhibits unique physiological activities in anti-oxidation, anti-inflammation, maintaining cardiovascular health, anti-cancer and other aspects, and has a positive impact on human health. ​

Powerful Antioxidant​

Curcumin is a powerful antioxidant that can neutralize free radicals, remove harmful oxidizing substances, and protect cells from oxidative damage. Free radicals are unstable molecules produced during the normal metabolism of the human body.

They are highly active and easily react with various biological molecules in cells, such as lipids, proteins, and DNA, thereby inducing oxidative stress.

Oxidative stress is closely related to the occurrence and development of a variety of chronic diseases, including cardiovascular disease, cancer, neurodegenerative diseases, etc., and is also one of the important factors leading to aging.

The phenolic hydroxyl group and unsaturated double bonds in the molecular structure of curcumin give it a strong free radical scavenging ability. It can stabilize free radicals by providing hydrogen atoms and convert them into relatively stable substances, thereby reducing the attack and damage of free radicals on cells.

From a long-term perspective, a moderate intake of curcumin-rich foods, such as turmeric, in the daily diet can help the human body maintain a low level of oxidative stress, reduce oxidative damage to cells and tissues, and thus help delay aging, prevent the occurrence of chronic diseases, and keep people younger and healthier. ​

Significant Anti-inflammatory Properties​

Curcumin has obvious anti-inflammatory effects. It can promote the production and activation of white blood cells, inhibit the release of inflammatory mediators, reduce inflammatory responses, and help relieve the symptoms of inflammatory diseases such as arthritis and intestinal inflammation.

The anti-inflammatory mechanism of curcumin is relatively complex, and it can exert anti-inflammatory effects through multiple pathways. Curcumin can also regulate the activity of other inflammation-related signaling pathways and enzymes, such as the mitogen-activated protein kinase (MAPK) signaling pathway, cyclooxygenase (COX) and lipoxygenase (LOX), further inhibiting the occurrence and development of inflammatory responses. ​

Benefits for Cardiovascular Health​

Curcumin can regulate blood lipid metabolism, reduce serum total cholesterol, low-density lipoprotein cholesterol and triglyceride levels, and help prevent atherosclerosis and cardiovascular diseases.

On the one hand, curcumin can reduce the synthesis of cholesterol by inhibiting the activity of key enzymes in cholesterol synthesis, thereby reducing serum total cholesterol and LDL-C levels.

On the other hand, the antioxidant effect of curcumin can inhibit the oxidative modification of LDL-C, reduce the generation of oxidized LDL-C, and reduce its damage to vascular endothelial cells, thereby reducing the formation of foam cells and delaying the progression of atherosclerosis.

Curcumin’s regulation of blood lipid metabolism helps improve cardiovascular health. Curcumin also has the effect of inhibiting platelet aggregation and reducing blood viscosity, which can improve blood rheology indicators, reduce the risk of thrombosis, and further protect the health of the cardiovascular system.

Anti-cancer Potential​

Curcumin has the effect of inhibiting the growth and spread of tumor cells. Studies have found that curcumin can inhibit the proliferation of tumor cells, induce tumor cell apoptosis, and inhibit the invasion and metastasis of tumor cells through various mechanisms, which makes curcumin a potential drug for cancer prevention and treatment.

In terms of inhibiting tumor cell invasion and metastasis, curcumin can inhibit tumor cells from secreting matrix metalloproteinases (MMPs). MMPs are a class of enzymes that can degrade the extracellular matrix and play an important role in the invasion and metastasis of tumor cells.

By inhibiting the activity of MMPs, curcumin can prevent tumor cells from breaking through the basement membrane and reduce the metastasis of tumor cells to surrounding tissues and distant organs.

A large number of in vitro cell experiments and animal experiments have confirmed the anti-cancer effect of curcumin. Although curcumin cannot be widely used as a single anti-cancer drug in clinical practice, it is used as an adjuvant treatment method in combination with traditional chemotherapy drugs. It is possible to improve the effect of chemotherapy and reduce the side effects of chemotherapy drugs, bringing new hope for the treatment of cancer. ​

Other Potential Benefits

Curcumin can stimulate the gastric mucosa to secrete gastric acid and gastric juice, promote the secretion of digestive juice, increase appetite, help digest food and relieve stomach discomfort. In some traditional medicines, turmeric is often used to treat gastrointestinal diseases, and modern research has further confirmed the role of curcumin in improving digestive function.

Curcumin also has the function of protecting nerve cells, can reduce nerve cell damage, and help prevent and treat neurodegenerative diseases such as Alzheimer’s disease. Curcumin also has antibacterial properties and can inhibit the growth of a variety of bacteria and viruses. This property makes curcumin have certain potential in enhancing immunity and preventing infectious diseases.
