| Abstract: | By using acetic ester as solvent, Tea Polyphenols and Catechin are separated from green tea. By applying the combination design of twice general rotaional method, based on the three expermental factors: tea (X 1), solvent (X 2), time (X 3), the mathematical model of the rate of extraction (Y) has been setup. According to system analysis on dynamic mapping during extraction, it gives a quantitaive base for untilizating extraction and separating Tea Polyphenols and Catechin. |
