Detailed Product Description

Theaflavins

In the processing of black tea, the tea pigment is formed by polyphenol type substances oxidized and polymerized. It contains theaflavins TF_s, thearubigins TR_s and theabrownine TB. Catechin forms theaflavins after oxidation, deoxidization and polymerization. Thearubigins is the production by oxidation and polymerization of theaflavins and some catechin. And thearubigins forms theabrownine by further oxidation and polymerization.

The most important pigment in tea pigment is theaflavins category which has various structures. The found and verified theaflavins have 13 types mainly FT_1, TF-3-G, TF-3´-G, TF-3,3´-DG etc.

Theaflavins abstraction shows orange powder and crystal and is easy to be dissolved in water, methanol, ethanol, acetone, and acetic acid but hard to be dissolved in ether and cannot be dissolved in chloroform and benzene.

Researches show that tea pigment mainly formed by theaflavins has the functions of reducing human blood mucosity, improve microcirculation, reduce cholesterol, reduce fibrinogen, anti-coagulation and improve fiber dissolution and regulate blood lipid as well as prevent angiocarpy and cerebrovascular diseases; meanwhile, it can also anti-oxidation, prevent and restrain cancer transformation and hyperplasia, anti-bacteria, anti-inflammation.
