Theaflavins are polyphenols that were found in
Black tea originally. The characteristic orange and brown colour of brewed black tea is mainly contributed by the presence of the theaflavins (TFs) and the thearubigens (TRs). They also give astringency and body to the brewed tea. TRs are larger in size and darker in colour than TFs.

Generally, to prepare black tea, fresh leaves of the plant Camellia sinensis are withered to lose moisture and bring about chemical/biochemical changes especially in aroma, then fermented, in which process Enzymes in the tea leaf use atmospheric oxygen to oxidise various substrates to produce coloured products, and then dried at high temperatures to stop the enzyme activities.

The chemical structures of the TFs are well known and the four main theaflavins are known as theaflavin (TF1), theaflavin-3-monogallate (TF2), theaflavin-3'-monogallate (TF3) and theaflavin-3-3'-digallate, (TF4). Theaflavins are produced during the oxidative fermentation of leaf tea to produce black tea, in which process polyphenol oxidase is responsible to oxidize polyphenols into theaflavins. Most theaflavins are known to be antioxidants. Therefore there is great interest in the food, dietary supplement and health-care industries in production and incorporation of theaflavins in various products.

Recent years more and more studies suggested that theaflavins show a range of functional properties, for example anti-inflammations and reduced LDL cholesterol in patients with raised cholesterol levels.
