Abstract: Based on the certain rate of tea and water, on the certain solubility, adopting quadratic regression analysis method, this essay sets up the regression equation on the total tea polyphenols and catechin. With better conducting, the experiment is done on the effect of soaking times upon the soak-ing liquid solubility and soaking rate, and it is the material for further research on tea polyphenols extraction technique.
