Green tea extract is the active ingredient extracted from green tea leaves, mainly including tea polyphenols (catechins), caffeine, aromatic oils, water, minerals, pigments, carbohydrates, proteins, amino acids, vitamins, etc. 
Tea polyphenols have antioxidant and free radical scavenging effects, and significantly reduce serum total cholesterol, triglyceride and LDL cholesterol content in hyperlipidemia, and also have the effect of restoring and protecting vascular endothelial function. The lipid-lowering effect of tea polyphenols is also one of the main reasons why tea can make obese people lose weight without rebound.

Green Tea Polyphenols (GTP) is the main component of green tea, accounting for about 30% of the dry matter, GTP is extracted from tea leaves and its by-products (tea powder, tea flakes, coarse tea or trimmed leaves). Since only food grade ethyl acetate is used for extraction, thus retaining the original structure of GTP, the product is a light yellow powder. The main component consists of catechins, which account for about 60%~80% of the total GTP, including 4%~6% epigallocatechin (L-EC), 6%~8% gallocatechin (D.L-EC), 10%~15% epigallocatechin (L-EGC), 50%~60% epigallocatechin gallate (L-ECG), and 8%~10% caffeine.
The GTP structure is rich in phenolic hydroxyl groups, which can provide active hydrogen to inactivate free radicals, while the free radicals formed by oxidation itself have high stability due to the catechol structure. Therefore, GTP has the effect of scavenging free radicals and inhibiting lipid peroxidation.
