Description of Green Tea Extract(Polyphenol,Catechins,EGCG)

Green tea extract exhibit stronger antioxidant protection for human body than vitamin C and vitamin E. Scavenging effect of lipid free-radicals (one antioxidant property) of polyphenols in green tea extract can be clearly observed in experiments. The ability of GTP in green tea extract to eliminate lipid-derived free radicals is noticeably stronger (almost 50 times) than that of ginkgo biloba extracts. Further investigations indicate that the boosting level of superoxide dismutase (SOD) and glutathione dismutase (GSHPx) may account for the inhibitory effect of GTC against lipid oxidation (rancidification). It should be mentioned that from the antioxidant perspective, green tea extract are, generally speaking, more effective than black tea extracts due to the better preservation of catechins.

Moreover, the anticarcinogenic property make the green tea extract a hotspot in recent scientific researches. In many experiments, green tea extract show inhibitory effects on cancer cells. In vitro assays, Catechin and caffeine, which are main components in green tea extract, block the cell cycle of cancer cells (cytotoxicity) and induce programmed cell death; in vivo, green tea extracts also inhibits prostatic carcinoma transplanted in nude mice.

In addition, green tea extract also contain a wide-ranged anti-inflammatory characteristics, so it may be helpful in treating chronic inflammatory states. The bactericidal activity against S.mutans is conspicuous in Japanese green tea extracts, and the maltose level in mouth is consistently lower after drinking tea. Therefore, green tea extracts may be effective in oral hygiene maintenance.
