Specification: 30% to 98% Polyphenols, 40% to 80% Catechins, 20% to 98% EGCG, 20%-98% Natural L-theanine
Green tea extract, like many herbs, is standardized in the production phase to guarantee that a certain percentage of the active ingredients remain present in the final capsulized form. The active ingredients in green tea extract are polyphenols in the form of flavonoids like catechins and epigallocatechin gallate (EGCG). Polyphenols, flavonoids, catechins and EGCG are powerful antioxidants that appear to interfere with and reduce the spread of certain types of cancer cells. The antioxidant activity of EGCG in green tea extract is purportedly up to 100 times more powerful than that of vitamin C or E.
2. Active Composition Tea polyphenols is the main ingredients in tea and take up 12-24% of the tea. It consists of catechin (flavanoid), flavones, anthocyanin and phenolic acids, among which catechin takes up 70-80% and is the key medicinal ingredient. EGCG is a important kind of catechin, its anti-oxidation is the most strong. Catechin includes below several kinds: L-EC, L-EGC,L-EGCG.L-ECG, (-)- epicatechin-3,5-digallated, eigollacatechin-3,5-di-gallate. among them, L-EGCG occupies 50%~60%, L-EGC 15%~20%, L-EGC 10%~15%, L-EC 5%~10%. 3. Main Functions: (1) With the function of anti-aging, eliminating free radicals; (2) With the function of anti-cancer, Inhibiting the increasing of cancer cell; (3) With the function of anti-bacterium, with the function of sterilization and deodorization; (4) With good inhibitory effect to HIV.
4. Applications: (1) Applied in food field, adds tea polyphenols in foods can maintain original flavor, preventing corruption and discoloration, with the function of restraining and killing bacteria, which will improve the food hygiene standards; (2) Applied in pharmaceutical field, it can be used to treat cardiovascular disease and cancer; (3) Applied in cosmetic field, protecting skin from the harmful sun exposure, which will prevent skin cancer. 5.
