EGCG（epigallocatechin gallate）, with molecular formula C22H18O11, is the main component of green tea polyphenols. It is a catechin monomer isolated from tea, and has many good effects,such as antibacterial, antiviral, antioxidant, anti-arteriosclerosis, anti-thrombosis, anti-angiogenesis, anti-inflammatory and anti-tumor etc.
Molecular Formula:C22H18O11
EGCG (Epigallocatechin gallate) is a component extracted from Chinese green tea. It is the main active and water-soluble component of green tea, and the component with the highest content of catechin, accounting for 9%-13% of the gross weight of green tea. Due to its special stereochemical structure, EGCG has very strong antioxidant activity. The antioxidant activity of EGCG is at least 100 times that of vitamin C and 25 times that of vitamin E, protecting cells and DNA from damage believed to be linked to cancer, heart disease and other major diseases. These effects are attributed to their scavenging ability of oxygen free radicals (antioxidant).
Epigallocatechin gallate plays an important role in cancer prevention and cardiovascular disease. In addition, it is also used as a reversal agent of multidrug resistance in tumors, improving the sensitivity of cancer cells to chemotherapy and reducing toxicity to the heart .
EGCG is the main component of green tea polyphenols and the main component of green tea catechins, including EGCG, EGC, ECG, EC and GCG, among which the antioxidant activity is EC in sequence. Many studies have shown that EGCG has anti-dna damage from free radicals, anti-radiation and ultraviolet rays, and can prevent oil peroxidation. To reduce serum cholesterol, low density, low density cholesterol and triglyceride levels, interferes with an signals needed for the survival of cancer cells and inhibition of carcinogenic substances in the diet, and intestines, liver, and other enzymes and antioxidants in the lung function together to prevent certain carcinogens vitality, scavenging free radicals, resist pollution, the sun, and the impact of smoking, prevention of skin aging and wrinkling.
