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.{{cite web|url=http://www.rxlist.com/theaflavin/supplements.htm|title=Theaflavin Effectiveness, Safety, and Drug Interactions on RxList|website=rxlist.com|access-date=24 April 2018|url-status=live|archive-url=https://web.archive.org/web/20170904203923/http://www.rxlist.com/theaflavin/supplements.htm|archive-date=4 September 2017}} Theaflavins are types of thearubigins, and are therefore reddish in color.
