Abstract:
A new method for the extraction of tea-polypbenols (TP ) from tea using AlCl3 as precipitating agents was proposed. Compared with tbe traditional extraction method using organic solvents, it is shown that the new method is simple and can be operated easily. The extraction rate of TP by the new method could reach 10.5% and the content of the effective ingredients of TP could reach over 99.5%
