Product Introduction

It is generally accepted that during the fermentation stage of black tea manufacture, flavan-3-ols (also known as catechins) of green tea leaf are oxidized enzymically and chemically to give rise to theaflavins and thearubigins (Roberts 1962; Sanderson 1972). Theaflavins possess a benzotropolone skeleton that is formed from co-oxidation of appropriate pairs of catechins, one having a vic-trihydroxyl structure, and the other having an ortho-dihydroxyl group. Several major theaflavins and related compounds have been structurally characterized. Theaflavin (TF), theaflavin-3-gallate(TF-3-G), theaflavin-3’-gallate(TF-3’-G), theaflavin-3, 3’-gallate (TFDG) and epitheaflavic acid are examples (Colier et al 1973).

Physiological Functions

Theaflavins are the most important active constituents of black tea extract. Theaflavins (TFs) possess various healthy and medicinal actions and will serve as effective anti-cardiovascular and blood vessel of brain, anti-atherosclerosis and anti-hyperlipodemia agents. American contemporary pharmacological studies show that TFs are more likely to be a new kind of anti-cardiovascular and blood vessel of brain drug and also to be a kind of natural aspirin.
