Uses and synthesis of Oleuropein powder

Oleuropein powder, also known as olive bitter glycosides, is a natural plant extract, Oleuropein CAS 32619-42-4 is mainly derived from the leaves of Olea europaea (olive tree), which belongs to the family of lignoceros family, the evergreen tree, is a world-famous tree species of woody oil and fruit.

Oleuropein Raw Materials has antioxidant, anti-inflammatory, antibacterial, antiviral, anticancer, antitumour and hypoglycaemic effects, and is gradually used in medicine, health food, cosmetics and other industries and has a broad application prospect.

Applications / Functions of Oleuropein powder

Oleuropein powder is used in the determination of content/identification/pharmacological experiments and other pharmacological effects: it has strong antibacterial and antiviral properties, and strong antioxidant capacity.

The pharmacological effects of Oleuropein CAS 32619-42-4 are mainly hypotensive, antioxidant, anti-microbial and anti-cancer.

Physicochemical Property of Oleuropein powder

Tiny crystals (ethyl acetate), melting point 87 ~ 89 ° C, easily hygroscopic, soluble in ethanol, acetone, glacial acetic acid, 5% NaOH solution, Oleuropein Raw Materials can be dissolved in water, butanol, ethyl acetate, butyl acetate, almost insoluble in ether, petroleum ether, chloroform, carbon tetrachloride.

Oleuropein powder will decompose when exposed to air and sunlight, it is recommended to keep it under low temperature and sealed under the condition of avoiding light.

Production methodprocess of Oleuropein powder

• 1, Ye Jianzhong used the process of hot reflux extraction to obtain the crude extract of olive bittersweet, after screening the AB-8 resin purification, AB-8 resin purification of the optimal conditions: on the sample mass concentration of 2g / L, 70% ethanol-water elution, flow rate of 3mL/min, the amount of eluent is 3BV, the final The purity of Oleuropein CAS 32619-42-4 reached 47.90%, the flavonoid content was 16.4%, and the yield was 6.43%.
• 2. Fu Shan et al. investigated the adsorption of olive bitter glycosides by six different macroporous resins, and screened out D101 macroporous adsorption resin with good adsorption selectivity. D101 resin was used as the adsorption material, and the best adsorption conditions were obtained: the sample on the sample mass concentration of 41.06 mg/mL, the flow rate of 5 mL/min, 50% ethanol solution elution, the amount of eluent 260 mL, the resin can be used repeatedly. The purity of Oleuropein Raw Materials could reach more than 55% after enrichment by macroporous resin, and more than 76% after purification by dextran gel.
