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).
