Product Profile
Theaflavins are an important quality ingredient and functional ingredient in black tea. They have various biological activities and pharmacological effects such as lowering blood lipids, lowering blood pressure, antioxidant, anti-radiation, antibacterial, and anti-cancer. They are known as the "soft gold in tea." , the theaflavins content in black tea is only 0.5%-2.0%.

Theaflavin is a golden pigment present in yellow tea and black tea, and is a product of tea fermentation.

Theaflavins are the general name for a class of compounds that are soluble in ethyl acetate and have benzophenones formed by the oxidation of polyphenols. Theaflavins have 12 components, including theaflavins (TF), theaflavins-3-gallate (TFMG), theaflavins-3,3'-digallate (TFdiG) and theaflavins -3'-Gallate (TFM'G) is the 4 most important theaflavins.

The purified product of theaflavins appears as orange-yellow needle-shaped crystals with a melting point of 237-240°C. It is easily soluble in water, methanol, ethanol, acetone, n-butanol and ethyl acetate, and is insoluble in ether. Insoluble in chloroform and benzene. Theaflavin solution is bright orange-yellow, and the aqueous solution is slightly acidic, with a pH of about 5.7. The color is not affected by the pH of the tea soup extract, but it has a tendency to auto-oxidize in alkaline solutions, which is enhanced as the pH increases.
