Description About Epigallocatechin Gallate (EGCG) CAS 989-51-5
Epigallocatechin gallate (EGCG), also known as Epigallocatechin 3-gallate, is the ester of epigallocatechin and gallic acid, and is a type of catechin. 
EGCG is the most abundant catechin in most notably tea, among other plants, and is also a potent antioxidant that may have therapeutic properties for many disorders including cancer. It is found in green tea, but not black tea, as EGCG is converted into thearubigins in black teas. In a high temperature environment, an epimerization change is likely to occur, because heating results in the conversion from EGCG to GCG. Thus it is considered inappropriate to infuse green tea or its extracts with overheated water.EGCG can be found in many supplements.
Researchers at the University of Kansas feel that EGCG is at least 100 times more effective than vitamin C and 25 times better than vitamin E at protecting cells and their genetic material, DNA, from damage believed to be linked to cancer, heart disease and other potentially life-threatening illnesses. EGCG, carries twice the antioxidant punch of resveratrol, found in red wine.
