Effect of tea extract:

1. Antioxidant effect
Tea polyphenols can directly scavenge reactive oxygen free radicals. The structure of tea polyphenols is rich in phenolic hydroxyl groups, which can provide active hydrogen to inactivate free radicals. The free radicals formed by oxidation have high stability due to the structure of catechol. Therefore, tea polyphenols are free radical inhibitors for hydrogen supply. Tea polyphenols can inhibit lipid peroxidation, chelate metal ions and activate intracellular antioxidant defense system.
2. Sterilization and antibacterial, improve the structure of intestinal microorganisms
Tea catechins have bactericidal and inhibitory effects on many harmful bacteria, such as Staphylococcus aureus, Vibrio cholerae, Escherichia coli and so on. Tea polyphenols can promote the growth and proliferation of many beneficial bacteria in the human intestine, such as bifidobacteria, which can not only produce many nutrients (such as B vitamins) in the intestine, but also inhibit the proliferation of harmful bacteria.
3. Antiviral effect
Tea catechins have inhibitory effect on influenza virus A and B; EGCG and ECG, even at low concentrations of 0.01 to 0.02mg/ml, have a strong inhibitory effect on HIV.
4. Reduce fat, lose weight and prevent atherosclerosis
Tea catechins, especially EGCG, can inhibit the synthesis of cholesterol in cells, reduce LDL cholesterol in blood and increase HDL cholesterol. The former can promote human atherosclerosis, while the latter can prevent and improve atherosclerosis.
5. Depressurization
Tea catechins, especially ECG and EGCG, significantly inhibited angiotensin I converting enzyme.
6. Dental caries prevention
Studies in the late 1980s found that polyphenols in tea are the most important effective substances in the anti caries effect of tea.
7. Other roles
Tea extract has hypoglycemic effect, anti radiation effect, anti allergy effect, enhancing immune function and preventing aging.
