Product information

Product use

Tea polyphenols, also known as Green Tea Extract Powder or tea catechins, are a class

of polyhydroxy compounds found in tea leaves. Recent studies have shown that tea

polyphenols possess a variety of biological functions, including antioxidant, antitumor,

anti-inflammatory, antibacterial, anti-radiation, stroke prevention, lipid-lowering, and

anti-aging effects. As a result, they have been widely applied in the fields of food and health

care, clinical medicine, and cosmetics.

Antioxidant Properties
Tea polyphenols are excellent natural antioxidants with significant antioxidant effects.

They eliminate excessive free radicals in the body, protect cell membrane structures, slow

down aging, and extend lifespan. Their antioxidant activity is closely related to the synergistic

effects among their components, with the optimal combination being EGCG

(epigallocatechin gallate): ECG (epicatechin gallate): EGC (epigallocatechin):
EC (epicatechin) = 5:2:2:1.

Moreover, tea polyphenols exhibit synergistic effects with other antioxidants such as

vitamin C, vitamin E, carotenoids, and glutathione, enhancing their overall antioxidant

efficacy. Extensive research shows that the anti-tumor, anti-aging, and lipid-regulating

pharmacological activities of tea polyphenols are closely related to their antioxidant

properties.

Lipid Regulation
Tea polyphenols Green Tea Extract Powder comprehensively regulate blood lipids,

particularly by reducing serum triglycerides (TG), total cholesterol (TC), and low-density

lipoprotein cholesterol (LDL-C), while increasing high-density lipoprotein cholesterol.

Additionally, tea polyphenols are potent inhibitors of low-density lipoprotein oxidation,

effectively preventing LDL oxidation and inhibiting factors contributing to atherosclerosis.

Antiviral and Antibacterial Effects
Tea polyphenols are widely recognized as a broad-spectrum, potent, and low-toxicity

antibacterial agent. Numerous studies have demonstrated their inhibitory and bactericidal

effects against various pathogens, including Proteus vulgaris, Staphylococcus aureus,

Staphylococcus epidermidis, Streptococcus mutans, Clostridium botulinum, Lactobacillus,
Vibrio cholerae, and oral Streptococcus mutans.

They are particularly effective against intestinal pathogens and can prevent

antibiotic-resistant Staphylococcus infections. Tea polyphenols also inhibit hemolysin

activity and strongly suppress pathogenic fungi causing skin diseases, such as Trichophyton

species. Furthermore, they protect beneficial intestinal bacteria.

Antitumor Effects
In vitro, tea polyphenols Green Tea Extract Powder exhibit antimutagenic properties and

inhibit carcinogen-induced tumors in rodents, including skin, lung, stomach, esophagus,

pancreas, prostate, duodenum, colon, and rectal tumors. The mechanisms of tumor inhibition

by tea polyphenols include antioxidant activity, free radical scavenging, blocking carcinogen

formation, and inhibiting metabolic activation.

They prevent the synthesis of highly carcinogenic nitrosamines and inhibit the activity

of cancer-promoting enzymes, such as telomerase. Tea polyphenols also enhance

immunity, reverse multidrug resistance in tumor cells, and influence the opening of the

mitochondrial permeability transition pore (PT pore), protecting mitochondria from

damage. Additionally, they inhibit tumor cell DNA synthesis, inducing DNA double-strand

breaks in a concentration-dependent manner, thereby suppressing tumor growth and

proliferation.
