Green tea extract is an 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, significantly reduce serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol in hyperlipidemia, and have the function of restoring and protecting vascular endothelial function. The lipid-lowering effect of tea polyphenols is also one of the main reasons why tea can help obese people lose weight without rebounding.
Green Tea Polyphenols (GTP) is the main component of green tea, accounting for about 30% of dry matter. GTP is extracted from tea leaves and their by-products (tea powder, tea leaves, rough tea or trimmed leaves). Since only food-grade ethyl acetate is used for extraction, the original structure of GTP is retained, and the product is a light yellow powder. The main components are catechins, accounting for about 60% to 80% of the total GTP, including 4% to 6% epicatechin (L-EC), 6% to 8% gallate catechin (D.L-EC), 10% to 15% epigallocatechin (L-EGC), 50% to 60% epigallocatechin gallate (L-ECG), and 8% to 10% caffeine.
GTP is rich in phenolic hydroxyl groups, which can provide active hydrogen to inactivate free radicals, and the free radicals formed by oxidation have high stability due to the catechol structure. Therefore, GTP has the effect of scavenging free radicals and inhibiting lipid peroxidation.
Health Care Function of Green Tea Extract
【Lipid-lowering effect】: Tea polyphenols can significantly reduce the serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels of hyperlipidemia, and at the same time 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 help obese people lose weight without rebounding.
【Antioxidant effect】: Tea polyphenols can block the lipid peroxidation process and increase the activity of enzymes in the human body, thereby playing an anti-mutation and anti-cancer role.
【Tumor inhibition effect】: Tea polyphenols can inhibit the synthesis of tumor cell DNA and induce the breakage of mutant DNA, thereby inhibiting the synthesis rate of tumor cells and further inhibiting the growth and proliferation of tumors.
【Bactericidal and detoxification effect】: Tea polyphenols can kill botulinum toxin and spores and inhibit the activity of bacterial exotoxins. It has antibacterial effects on various pathogens that cause diarrhea, respiratory tract and skin infections. Tea polyphenols have a significant inhibitory effect on Staphylococcus aureus and Bacillus proteus that cause suppurative infections, burns and trauma.
【Detoxification and liver protection effect】: Alcoholic liver damage is mainly caused by free radical damage caused by ethanol. Tea polyphenols, as a free radical scavenger, have the effect of inhibiting alcoholic liver damage.
【Detoxification effect】: Severe environmental pollution has a significant toxic effect on human health. Tea polyphenols have a strong adsorption effect on heavy metals and can form complexes with heavy metals to produce precipitation, which is beneficial to reduce the toxic effects of heavy metals on the human body. In addition, tea polyphenols can improve liver function and diuresis, so they have a good anti-alkaloid poisoning effect.
【Improve the body's immunity】: Tea polyphenols can improve the overall immunity of the human body by increasing the total amount of immunoglobulin and maintaining it at a high level, stimulating changes in antibody activity, and promoting the body's self-regulation function.
