摘　　要：以乙醇浓度、浸提时间、浸提次数和浸提温度为考查因素,采用正交试验法对北沙参中水溶性多糖进行提取优化实验,结果表明:醇析浓度85%,浸提时间2.0 h,浸提次数3次,浸提温度80℃为最佳提取条件。北沙参水溶性多糖的提取率为2.4%,多糖相对含量为90%。The ethanol concentration for precipitation, extraction time, extraction times and extraction temperature were selected as four factors to design the orthogonal test and the optimum condition of extraction techniques was obtained. The results show the optimum condition for the extraction technique is as follows： ethanol concentration for precipitation is 85% ,extraction time is 2.0 h,extraction times is 3 and extraction temperature is 80 ℃. The extraction ratio of polysaccharide from Glehnia littoralis is 2.4% and the polysaccharide content is 90%.
