摘　　要：采用微波协助提取山药低聚糖,在单因素试验的基础上对微波功率、乙醇浓度、料液比和微波处理时间进行正交试验,结果显示,影响山药低聚糖提取率的因素主次顺序为乙醇浓度,微波处理时间,料液比,微波功率,微波协助提取山药低聚糖的最佳工艺条件为微波功率130W,乙醇体积分数为60%vol,料液比为1∶30(g∶mL),微波处理时间6min。The microwave extraction and measurement of oligosaccharide from Chinese Yam was studied. According to the single factor experiment, the optimal condition for extracting oligosaccharide was obtained through orthogonal test： extraction power 130W, extraction time 6min, the ratio of solid to 60%vol ethanol 1：30（g：ml）. The order of affecting the factors was ethanol volume fraction, extraction time, the solid to liquid ratio and microwave power.
