What Is Oleuropein Powder?

Olive leaf phenolic extract has approximately twice the antioxidant potential of green tea extract. This black fine powder is C25H32O13 (CAS: 32619-42-4) with 540.51 Da molecular weight.

Our novel extraction method may be adjusted to 10%, 20%, 40%, 50%, 60%, and 70% purity and validated by HPLC. The powder lasts 3 years at -20°C in sealed, light-protected packaging.

This versatile chemical satisfies important industrial needs for clean-label antioxidants, having good free radical scavenging characteristics and high flowability for encapsulation and tableting procedures.

Functions

Oleuropein has many proven pharmacological activities:

Antioxidant Protection: Prevents damage by hydroxyl and superoxide radicals, protecting the cells from oxidative stress. This feature makes it a superior anti-aging substance.

Cardiovascular Support: Supports healthy blood pressure and good vascular function via support of endothelial health.

Blood Sugar Balance: Aids in the proper metabolism of blood sugar and insulin sensitivity, hence useful in blood sugar support formulations.

Anti-inflammatory Activity: Modulates inflammatory pathways, decreases indicators of chronic inflammation linked to metabolic syndrome.

Antimicrobial Action: Natural antibacterial action against common infections, broadening its use in preservation systems.

Application Fields

Dietary Supplements: The primary active ingredient in capsules for cardiovascular health, tablets for metabolic support and antioxidant complex formulations for the longevity and healthy ageing markets.

Nutricosmetics: Added to beauty-from-within oral powders and skin rejuvenation mixes, capitalising on its UV-protective and collagen-preserving qualities for anti-photoaging applications.

Functional Foods: Used in health drink mixes, nutrition bars and fortified drinks, where natural phenolic content and clean-label appeal are important differentiators.

Cosmetic Raw Materials: Used in skin care serums and anti-aging formulas for its demonstrated ability to protect dermal structures from external stresses and promote skin barrier function.

Pharmaceutical Intermediates: A standardised botanical raw material for evidence-based herbal medicine formulations needing uniform bioactive content.
