Olive Leaf Extract Powder Description
Olive leaf extract powder is a fine, hygroscopic powder with a light brown to yellowish color, characterized by a distinct bitter taste and herbal aroma. The extract is rich in bioactive compounds, primarily oleuropein (standardized to 10–40%), along with hydroxytyrosol, flavonoids (luteolin, apigenin), and triterpenes (oleanolic acid).
Key Properties:
- Thermal Stability: Degrades above 60°C but remains stable in dark, dry conditions (<25°C).
- Solubility: pH-dependent—readily dissolves in hydroalcoholic solutions but may form colloidal suspensions in water due to polyphenol aggregation.
- Antioxidant Activity: Exhibits strong free-radical scavenging capabilities, outperforming synthetic antioxidants like BHT. Hydroxytyrosol further enhances mitochondrial function and protects against lipid peroxidation.
- Stability Requirements: Sensitive to UV light and oxygen; trace metals (e.g., iron) are controlled below 0.5 mg/kg to prevent catalytic degradation.
- Quality Standards: Complies with pharmacopeial limits for heavy metals (lead ≤20 ppm) and microbial safety.
Synergistic interactions between oleuropein and flavonoids enhance bioavailability, making the extract highly effective in various applications.

Olive Leaf Extract Powder Applications
1. Pharmaceuticals & Nutraceuticals
- Immune Support: Enhances macrophage activity and inhibits viral replication (e.g., HSV, HIV), reducing cold/flu duration by 1–4 days at doses of 300–500 mg/day.
- Cardiovascular Health: Helps manage hypertension by relaxing vascular smooth muscle, lowering systolic blood pressure by 8–10 mmHg.
2. Cosmetics & Personal Care
- Anti-Aging: At 0.5–5% concentrations, oleuropein inhibits collagenase and elastase, reducing wrinkles by up to 40% and protecting against UV-induced DNA damage.
- Skin Protection: Hydroxytyrosol combats oxidative stress from pollution, improving skin elasticity and reducing hyperpigmentation in sunscreens and reparative creams.
3. Functional Foods & Beverages
- Natural Preservative: Reduces lipid peroxidation in meats by 17.8%, extending shelf life.
- Enhanced Nutrition: Combines with vitamin C in functional drinks to boost antioxidant delivery and support endothelial function.
4. Agriculture & Biopesticides
- Biofungicide: Effective against crop pathogens like wheat rust.
- Eco-Friendly Pest Control: Disrupts insect larval development and fungal growth, ideal for organic farming.
5. Biomedical Research
- Cancer Research: Studied for its chemopreventive effects in breast and prostate cancers via apoptosis induction.
- Neuroprotection: Hydroxytyrosol-nanoparticle complexes are being explored for targeted drug delivery in neurodegenerative disorders.
Olive Leaf Extract Powder FAQs
Q1. How soon for blood pressure benefits?
Most users see a systolic pressure drop within 4–6 weeks of 400 mg/day. Pair with magnesium for enhanced effects.
Q2. Does heat destroy its active compounds?
Yes. Degradation occurs above 60°C. Add powder to cold smoothies or yogurt; never boil. Store below 25°C.
Q3. How to verify oleuropein potency?
Request Certificates of Analysis (CoA) confirming ≥10% oleuropein via HPLC and heavy metals (Pb ≤20 ppm).
