Olive Extract
Oleuropein
Oleuropein is signature secoiridoid‑type polyphenol extracted from mature dried olive leaf of Olea europaea. It can be hydrolyzed into hydroxytyrosol inside biological system. We supply multiple HPLC‑standardized grades from enriched olive‑leaf extract up to high‑purity 98% monomer for nutraceutical and cosmetic applications
Non‑GMO, complying with ISO22000, HACCP, GMP, HALAL & KOSHER, FDA‑GRAS reference documents and CosIng database. Widely used in Mediterranean‑concept olive‑polyphenol capsules, herbal antioxidant powder, anti‑inflammatory soothing serum and anti‑photo‑aging brightening mask formulas. Stable batches, factory wholesale price, free samples and complete COA, HPLC chromatogram & SDS documents are provided.

Core Benefits & Functional Mechanism
Oleuropein is characteristic secoiridoid polyphenol marker substance of olive leaf. It delivers powerful antioxidant and anti‑inflammatory activity and can be biologically hydrolyzed to hydroxytyrosol. For nutraceuticals, it serves as core raw material for Mediterranean‑style olive‑polyphenol oral supplements. For cosmetics, it relieves skin inflammatory irritation, resists UV‑caused photo‑oxidative injury, inhibits tyrosinase activity and improves dull uneven skin tone.
Classic compound collocation: compound with Hydroxytyrosol to construct complete olive‑polyphenol complex system; match Resveratrol / Astaxanthin for multi‑dimensional antioxidant compound formulas. Avoid long‑term exposure to high‑temperature and strong‑alkaline surroundings.
- Signature olive‑leaf secoiridoid polyphenol, biological convertible to hydroxytyrosol.
- Nutraceutical: Mediterranean‑concept oral antioxidant supplement raw.
- Cosmetic anti‑photoaging: protect skin against UV‑triggered oxidative damage.
- Anti‑inflammatory soothing: calm irritated skin and support barrier recovery.
- Brightening effect: inhibit tyrosinase activity, ameliorate oxidative‑induced dull complexion.
- Multiple HPLC‑standardized grades, dual‑grade fit oral supplement and topical cosmetic.
Tip: Nutraceutical serving:40‑150mg per serving (Oleuropein basis); cosmetic addition:0.1‑3.0%. Keep finished goods light‑proof & low‑temp; maintain pH3.0‑5.0; strictly prevent raw‑material moisture‑absorption caking.
