摘　　要：以葡萄皮渣为研究对象,采用单因素分组实验法及正交试验法对葡萄皮渣中多酚超声波的提取工艺进行了初步探讨,比较了提取时间、温度、提取次数、料液比等因素对多酚提取量的影响.超声波提取法的最佳工艺条件为:料液比1∶6(g/mL),时间45min,温度45℃,提取次数1次,超声波功率100 W.This paper studied on the extraction of polysaccharides from grape skin and seed with a single factor experiment and orthogonal experiment in different experimental groups, the effects of various factors, such as extracting time, temperature, times,ratio of liquid to solid and the quantities of solvent etal on the producing rate of with ultrasounic method are solid liquid ration 1g：6mL, the extraction temperature 35℃, time 45min, ultrasounic power 100W. The results demonstrated that ultrasounic method had many advantages, such as saving time, low energy consumption, favorable profiting environmental protection, easy operation and so on.
