Abstract：As a class of important physiological active substances, polyphenols has the function of resisting oxidation, beauty and nutrition and so on. Apple peel is rich in polyphenols. Extracting polyphenols from apple peel will be a new way on subsequent processing about apple peel. In this paper, the method of microwave extraction was used to extract polyphenols from apple peel. The effects of different ethanol concentration, solid-1iquid ratio, extraction time and microwave power by single factor experimentation was investigated in detail. By orthogonal test, the optimal conditions for extraction is obtained: ethanol at the concentration of 60% , and solid-1iquid ratio is 1:40, and the power is 600W for 50s. Polyphenol rate is 0.28%.
