What is EGCG?

Epigallocatechin gallate (EGCG) is a catechin monomer isolated from tea leaves, It is a tea extract with the molecular formula C22H18O11. As the main component of green tea polyphenols, EGCG has the highest content among catechins, accounting for 9%-13% of the gross weight of green tea. It is not only the core substance of green tea activity, but also one of the most promising special chemical substances in tea. EGCG is a white powdery phenolic acid compound with a purity usually higher than 99%, and the detection method is HPLC. EGCG has a stable chemical structure and is a very strong antioxidant raw material. Its antioxidant capacity is at least 100 times that of vitamin C and 25 times that of vitamin E. This powerful antioxidant capacity enables EGCG to protect cells and DNA from damage, which is closely related to major diseases such as cancer and heart disease. Therefore, it can be widely used as pharmaceutical raw materials and food additives.

What are the effects of EGCG?

1. Anti-tumor effect: EGCG has significant anti-tumor effects by interfering with cancer cell signal transmission and inhibiting the activity of carcinogens, and has the potential to prevent and treat a variety of cancers.
2. Antioxidant and anti-aging: It is an anti-oxidant raw material that can scavenge free radicals, protect cells and DNA from oxidative damage, and delay the aging process.
3. Cardiovascular protection: It can reduce low-density lipoprotein (LDL) and triglyceride levels, reduce the risk of cardiovascular disease, while improving heart function and improving cardiovascular health.
4. Antibacterial and antiviral: It has antibacterial ingredients and antiviral activity, which can inhibit the growth and reproduction of a variety of bacteria and viruses and enhance immunity.
5. Anti-inflammatory and anti-thrombotic: EGCG maintains vascular health by inhibiting inflammatory responses, reducing the release of inflammatory mediators, and inhibiting platelet aggregation and thrombosis.
6. Improve metabolic diseases: It has a positive effect on improving metabolic diseases such as obesity and diabetes, so it is also a weight loss extract.

What are the applications?

1. Food additives: EGCG, as a natural antioxidant, can be used to extend the shelf life of food, maintain the freshness and nutritional value of food, and can also be used as a deodorant to improve the taste of food.
2. Pharmaceutical raw materials: It can be used to make anti-cancer drugs, cardiovascular drugs, antibacterial drugs, etc., and as an additive to healthy foods to enhance human immunity.
3. Cosmetics materials: It has beauty effects such as moisturizing, whitening, and anti-wrinkle. It can be used to make skin care products, cosmetics and other daily chemical products, improve product quality, and meet consumers' pursuit of beauty.
