Our product, EGCG is a kind of component extracted from Chinese green tea. It is the primary active and water-soluble component of green tea, which has the highest content among the the tea catechins. It accounts for 9-13% of green tea in net weight. By virtue of its peculiar stereochemical structure, EGCG possesses much stronger anti-oxidant activities and plays an important role in preventing cancer and cardiovascular diseases. In addition, it is potent as the reversal agent of MDR (Multidrug Resistance). As such, it may improve the sensitivity of cancer cells to chemotherapy drugs and reduce toxicity on the heart.

(-)-Epigallocatechin gallate (egcg), an most potent antioxidant polyphenols of green tea, is associated with antioxidant, antitumor and antimutagenic activities. The antioxidant activity is at lest 100 times effective than vitamin C and 25 timeseffective than vitamin E at protecting cells and DNA from damage which are believed to be linked to cancer, heart disease and other potentially fatal illnesses. The biological benefits of EGCG are generally attributed to their antioxidant activity to scavenge free radical oxygen.
EGCG is the major component of the polyphenolic fraction of green tea. It makes up about 10-50% of the total green tea catechins includeing epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicatechin gallate(ECG), epicatechin(EC), gallocatechin gallate (GCG), catechin are major catechin of green tea catechin. The antioxidant activity increased in the following order: EC<ECG<EGC<EGCG.
Many studies indicate EGCG plays a role, which 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.
