Theaflavin (TF) and its derivatives, known collectively astheaflavins, are antioxidant polyphenols that are formed from thecondensation of flavan-3-ols in tea leaves during the enzymaticoxidation (fermentation) of black tea.

 

Theaflavin-3-gallate, theaflavin-3'-gallate,theaflavin-3-3'-digallate are the principle of theaflavins.Theaflavins are types of thearubigins, and are therefore reddish incolor. Epigallocatechin gallate (EGCG) will metabolize into sometheaflavins in the liver.

 

What is Black Tea Extract Theaflavines?

 

Theaflavins are a group of molecules that are created fromGreen Tea Catechins when heat treatment damages the catechinmolecule and they begin to resynthesize in various configurations;Theaflavins are the product of two catechin molecules bindingtogether on the C ring, and similar to catechins can come invarious gallated forms (whether there is gallic acid moleculesbound to them or not).

 

Main functions of Black Tea Extract Theaflavine:

1. Prevent and Cure all kinds of tumor&Cancer

2. Regulate blood fat, anti-atherosclerosis

3. Anti-biosis, eliminate inflammation, Anti-Virus

4. Anti-oxidant effectively
