Plant Extract

Theaflavins are a tea pigment found during the fermentation of black tea. They are a class of substances with a benzophenone ring structure formed by the oxidation and condensation of tea polyphenols and turn orange-yellow after being dissolved in ethyl acetate. Theaflavins are generally extracted and separated from black tea. China's tea-producing areas such as Fujian, Zhejiang, Yunnan and other places have become the main suppliers of theaflavins raw materials due to their unique natural conditions and long planting history.
