Theaflavin IUPACname: 3, 4, 5-Trihydroxy-1, 8-bis[(2R, 3R)-3, 5,7-trihydroxy-2-chromanyl]-6-benzo[7]annulenone CAS No.: 4670-05-7Formula: C29H24O12 Molar mass: 564.49 g/mol Appearance: Red brownfine powder Solubility Easy dissolving in water or enthanolTheaflavin (TF) and its derivatives, known collectively astheaflavins, are antioxidant polyphenols that are formed from thecondensation of flavan-3-ols in tea leaves during the enzymaticoxidation (fermentation) of black tea. Theaflavin-3-gallate,theaflavin-3'-gallate, theaflavin-3-3'-digallate are the principleof theaflavins. Theaflavins are types of thearubigins, and aretherefore reddish in color. Epigallocatechin gallate (EGCG) willmetabolize into some theaflavins in the liver. What is Black TeaExtract Theaflavines? Theaflavins are a group of molecules that arecreated from Green Tea Catechins when heat treatment damages thecatechin molecule and they begin to resynthesize in variousconfigurations; Theaflavins are the product of two catechinmolecules binding together on the C ring, and similar to catechinscan come in various gallated forms (whether there is gallic acidmolecules bound to them or not). Main functions of Black TeaExtract Theaflavine: 1. Prevent and Cure all kinds oftumor&Cancer 2. Regulate blood fat, anti-atherosclerosis 3.Anti-biosis, eliminate inflammation, Anti-Virus 4.
