What is Tea Polyphenol?
Tea Polyphenols Powder is a kind of natural active substance extracted from tea, which is gradually recognized by people for its good antibacterial, antioxidant and other biological properties, and is now used in food, medicine, daily chemicals and other fields.
Tea polyphenols are the general term for polyphenols in tea, and are known as "radiation nemesis" by the health and medical circles. It is an amorphous powder, easily soluble in water, soluble in ethanol, methanol and ethyl acetate, but insoluble in chloroform. Its main components are 6 types of compounds: flavanones, anthocyanins, flavonols, anthocyanins, phenolic acids and depsidic acids. Among them, flavanones (mainly catechins) are the most important, accounting for 60%-80% of the total tea polyphenols.
