Our product, EGCG is a kind of component extracted from the Chinese green tea. It is the mainly active and water-soluble component from green tea, whose content is the highest in 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 from cancer and cardiovascular diseases. In addition,it is potently used as the reversal agent of MDR (Multidrug Resistance), which may improve the sensitivity of the cancer cell to the chemotherapy drug and reduce the toxicity on the heart.
