Synonimy: Green Tea Extract, Camellia sinensis extract, Tea polyphenols, EGCG extract, Green tea catechin extract, Camellia sinensis leaf extract

Green tea extract is a concentrated source of polyphenols, particularly catechins such as epigallocatechin gallate (EGCG), which are responsible for its potent antioxidant and health-promoting properties. The extraction process preserves these delicate compounds, yielding a standardized powder that is widely used in dietary supplements, functional foods, and cosmetic formulations.

The extract is derived from the leaves of Camellia sinensis, a plant native to Asia and cultivated globally. The leaves are harvested, dried, and extracted using water or a hydroalcoholic solvent, followed by concentration and spray-drying to produce a fine powder. Standardization ensures consistent levels of active constituents, typically polyphenols and EGCG, meeting the rigorous demands of B2B buyers.

With its broad spectrum of biological activities, green tea extract is a key ingredient in products targeting weight management, cardiovascular health, and antioxidant support. Its versatility and well-documented safety profile make it a staple in the nutraceutical and cosmetic industries.

Struktura chemiczna i właściwości

The primary bioactive compounds in green tea extract are catechins, a family of flavan-3-ols. EGCG, the most abundant and studied catechin, features a gallate moiety esterified to the C-3 position of the flavan skeleton. These polyphenols are water-soluble, heat-sensitive, and exhibit strong radical-scavenging activity due to their multiple hydroxyl groups. The extract also contains minor amounts of caffeine and amino acids like L-theanine, which contribute to its overall profile.

Mechanizm działania

• Antioxidant activity: Catechins neutralize free radicals and chelate metal ions, reducing oxidative stress.
• Thermogenesis and fat oxidation: EGCG inhibits catechol-O-methyltransferase (COMT), prolonging norepinephrine action and enhancing energy expenditure.
• Anti-inflammatory effects: Suppresses NF-κB and COX-2 pathways, lowering inflammatory cytokines.
• Cardiovascular support: Improves endothelial function and lipid profiles by modulating nitric oxide production.
