Theaflavin powder Raw Materials CAS 4670-05-7
Product Overview:
Theaflavin powder is an important quality and functional component in black tea. It has various biological activities and pharmacological effects such as lowering blood lipids, lowering blood pressure, anti-oxidation, anti-radiation, antibacterial and anticancer, and is known as "soft gold in tea". Theaflavin content in black tea is only 0.5% to 2.0%. Theaflavin is a general term for a class of phenolic compounds that are soluble in ethyl acetate. Theaflavin's purified substance is orange yellow needle-like crystal, melting point 237 ~ 240℃, easily soluble in water, methanol, ethanol, acetone, n-butanol and ethyl acetate, but insoluble in ether. Insoluble in trichloromethane and benzene.

Uses and synthesis of Theaflavin powder
Theaflavin powder is an important quality and functional component in black tea. It has various biological activities and pharmacological effects such as lowering blood lipids, lowering blood pressure, anti-oxidation, anti-radiation, antibacterial and anticancer, and is known as "soft gold in tea". Theaflavin content in black tea is only 0.5% to 2.0%. Theaflavin is a general term for a class of phenolic compounds that are soluble in ethyl acetate. Theaflavin's purified substance is orange yellow needle-like crystal, melting point 237 ~ 240℃, easily soluble in water, methanol, ethanol, acetone, n-butanol and ethyl acetate, but insoluble in ether. Insoluble in trichloromethane and benzene.
Applications/Functions of Theaflavin powder
- Theaflavin powder can inhibit the proliferation and induce apoptosis of human nasopharyngeal carcinoma CNE2 cells in a time - and dose-dependent manner, and its mechanism may be related to the expression of genes regulating cell proliferation and apoptosis.
- Theaflavin can effectively delay the inflammatory degeneration of rat chondrocytes by enhancing the activity of chondrocyte synthesis factors, weakening the activity of decomposing factors and inhibiting the inflammatory response of cells, and has a certain protective effect on inflammatory chondrocytes.
Physicochemical Property of Theaflavin powder
Theaflavin's purified substance is orange yellow needle-like crystal, melting point 237 ~ 240℃, easily soluble in water, methanol, ethanol, acetone, n-butanol and ethyl acetate, but insoluble in ether. Insoluble in trichloromethane and benzene. Theaflavin solution is a bright orange-yellow color, and the aqueous solution is weakly acidic with a pH of about 5.7. The color is not affected by the pH of the tea extract, but has a tendency of automatic oxidation in the alkaline solution, and it is strengthened with the increase of pH.
