摘　　要：为从桑根皮中高效提取桑皮素A,在比较超声波和冷浸提取两种提取方法效果的基础上,研究以不同体积分数乙醇为溶剂,以冷浸法为对照,通过单因素和正交试验,对桑树根皮中的桑皮素A进行提取。结果表明其最佳条件是:乙醇体积分数为100%,料液比为1:30(g/ml),浸泡1h后超声处理45min,其桑根皮中桑皮素A的得率可达到1.734%。Two methods, i.e., ultrasonic assisted extraction and cold soaking extraction method, for extraction of mulberroside A from mulberry root cortex were compared, and the effects of ethanol concentration, ratio of raw material to ethanol, soak time or extraction time on the yield of mulberroside A were studied. An orthogonal test was employed to optimize the ultrasonic assisted extraction process. Results suggested that the optimum conditions were that mulberry root cortex was extracted with anhydrous ethanol for 45 min after cold soaking for 1 h, with the ratio of raw material to ethanol at 1：30 （g/ml）. Under such conditions, the yield of mulberroside A was 1.734%.
