Catechin type is composed of D,L-C、EC、EGC、EGCG、GCG、ECG and so on, the first three types are the simple catechin ( free type), the latter three types are the complex catechin (ester type). Catechin compound is apt to show oxidation, polymerization and condensation for containing more phenolic hydroxyl group, which is doomed to have fine ability of anti-oxidation and ability of clearing free radical.
Tea polyphenols extracted from tea is taken as natural antioxidant of food, it is used for grease and food containing oil, as continual intensive researching, it has been widely suitable for food, medicine, health products, chemical industry commodities. It's function as follows: anti-oxidation, anti-aging, anti- radiation, anti-ultraviolet, reducing blood fat, reducing blood sugar, anticancer and diseases of cardiovascular resisting, remove free radical, restraining pathogen and get ride of smell.
