Ultrasonic extraction was adopted to extract polysaccharides and proanthocyanidins from tea(Camellia oleifera Abel) seed shell,and the parameters which affected on the integrated extraction were studied.Results showed that the effect of ultrasonic power,ratio of solid to solution,ethanol concentration,extraction temperature,extraction time on the integrated extraction were remarkable,and the optimum extraction conditions were confirmed,as follows: the power of ultrasonic wave 400 w,the ratio of solid to solution 1 g∶ 70 mL,40% ethanol as solvent,extraction tem-perature 60℃,extraction time of ultrasonic wave 30 min.Under this condition,the yield of polysaccharides and pro-anthocyanidins were 0.27% and 2.09%,respectively.
