Background

Tea polyphenols are the general name of polyphenols in tea, and are white amorphous powder, which are easily soluble in water, soluble in ethanol, methanol, acetone, ethyl acetate, and insoluble in chloroform. The green tea has high tea polyphenol content accounting for 15-30% of the weight, and the tea polyphenol comprises the following main components: flavanones, anthocyanidins, flavonols, anthocyanins, phenolic acids and depside 6 compounds. Wherein, flavanones (mainly catechin compounds) are the most important and account for 60 to 80 percent of the total amount of tea polyphenol, and flavonoids and other phenolic substances are less.
