1. Antioxidant properties
Green Tea Extract Liquid possesses the ability to directly neutralize reactive oxygen free radicals. The tea polyphenols found in the extract contain phenolic hydroxyl groups, which can provide active hydrogen to deactivate free radicals. Additionally, the catechol structure present in the tea polyphenols enhances their stability and makes them effective hydrogen-donating free radical inhibitors. Furthermore, tea polyphenols can inhibit lipid peroxidation, chelate metal ions, and activate the body’s natural antioxidant defense system.
2. Anti-cancer and anti-mutation effects
Green Tea Extract Liquid has been shown to inhibit various animal tumors induced by carcinogens, including tumors in the skin, lungs, stomach, esophagus, colon, and duodenum. The mechanisms behind its anti-cancer effects are multifaceted and include inhibiting cancer cell proliferation, blocking carcinogen production, antioxidant effects, anti-mutation effects, influencing the immune system, and more. Among the active ingredients in the extract, CG and ECG are particularly important in exerting anti-cancer and anti-mutation effects.
3. Antimicrobial and intestinal health benefits
The catechin compounds in Green Tea Extract Liquid demonstrate bactericidal and inhibitory effects against several harmful bacteria such as Staphylococcus aureus, Vibrio cholerae, and Escherichia coli. Moreover, the extract promotes the growth and proliferation of beneficial bacteria in the human intestine, such as bifidobacteria. These beneficial bacteria not only produce essential nutrients like B vitamins but also inhibit the growth of harmful bacteria.
4. Antiviral effects
Tea catechins have been found to inhibit influenza viruses A and B. Even at low concentrations of 0.01 to 0.02 mg/ml, EGCG and ECG exhibit potent inhibitory effects on HIV.
5. Weight management and prevention of atherosclerosis
Tea catechins, particularly EGCG, can inhibit cholesterol synthesis in cells and have been shown to lower LDL cholesterol while increasing HDL cholesterol levels in the blood. LDL cholesterol promotes atherosclerosis, while HDL cholesterol helps prevent and improve it.
6. Blood pressure regulation
Tea catechins, especially ECG and EGCG, have a significant inhibitory effect on angiotensin I converting enzyme, which plays a role in regulating blood pressure.
7. Dental health benefits
Studies conducted in the late 1980s identified polyphenolic compounds in tea as the key substances responsible for its anti-caries effects, helping to strengthen teeth and prevent tooth decay.
8. Additional benefits
Green Tea Extract Liquid has been associated with various other health benefits, including its hypoglycemic effect, anti-radiation properties, anti-allergic effects, enhancement of immune function, and potential for preventing aging.
