Introduction of Tea Polyphenols:
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.

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%.
