Theaflavin (TF) and its derivatives, known collectively as theaflavins, are antioxidant polyphenols that are formed from the condensation of flavan-3-ols in tea leaves during the enzymatic oxidation (sometimes erroneously referred to as fermentation) of black tea. Theaflavin-3-gallate, theaflavin-3'-gallate, and theaflavin-3-3'-digallate are the main theaflavins.[1] Theaflavins are types of thearubigins, and are therefore reddish in color. Those molecules contain a tropolone moiety.
Certain benefits of black tea containing TFs can include the ability to whiten skin in cosmetics[2] and support antiobesity by affecting lipid metabolism.[3][4]
