摘　　要：在单因素试验的基础上采用正交试验得出了超声波提取山药多糖的最佳试验条件,即超声功率1000W、超声时间50min、提取温度60℃、料液比12.5g/L。该工艺与传统的水提取法相比,得率提高两倍多,提取时间也缩短为50min。Utilizing orthogonal test of the ultrasonic extraction of polysaccharides from Chinese yam, based on the result of single factor influence. An optimum extracting condition put forward as follows： ultrasonic power 1000W, extracting time 50 minutes, extracting temperature 60℃, material-water ratio 12.5g/L. Compared with conventional method, the polysaccharides recovery by ultrasonic extraction was about two times higher and the extracting time shortened within 50 minutes as well.
