It makes up about 10-50% of the total green tea catechins including epigallocatechin gallate(EGCG), epigallocatechin(EGC), epicatechin gallate(ECG), epicatechin(EC), gallocatechin gallate(GCG), etc. The antioxidant activity increases in the order of EC

Many studies indicate EGCG protects aganist free-radical DNA damage, protects aganist the effects of ionizing radiation and ultraviolet radiation, inhibits lipid peroxidation, decreases serum cholesterol levels, LDL, VLDL and triglycerides, interferes with the binding of cancer-causing agents to cellular DNA, helps to neutralize dietary carcinogens, works with enzymes and other antioxidants in the intestine, liver and lungs to prevent the activation of certain carcinogens before they damage DNA. As a free radicals scavenger, EGCG combats the effects of pollution, sunlight and smoking, helps skin from wrinkling and aging.
