白僵蚕是重要的中药材,采用微波辅助法释放白僵蚕的多糖成分。以白僵蚕多糖提取率为评价指标,采用微波辅助法提取分离白僵蚕多糖,用单因素实验法对影响多糖得率的料液比、微波功率、照射时间、提取次数4个因素进行了分析,用正交试验法优化白僵蚕多糖的提取工艺条件,提取白僵蚕多糖成分的最佳条件为:料液比1∶30、微波功率480W、提取次数3次、照射时间60s。在此提取条件下白僵蚕多糖干料的提取率为11.51%。
White silkworm is an important Chinese herbal medicine, using microwave-assisted release of white silkworm polysaccharides. The extraction rate of white silkworm polysaccharides was used as evaluation index. Microwave-assisted extraction and isolation of white silkworm polysaccharides were carried out. Four factors affecting the yield of polysaccharide, such as the ratio of solid to liquid, microwave power, irradiation time and the number of extraction, were determined by single factor experiment The optimum conditions for polysaccharides extraction were as follows: the ratio of material to liquid was 1:30, the microwave power was 480W, the extraction times were 3 times and the irradiation time was 60s. Under this condition, the extraction rate of white silkworm polysaccharide dry material was 11.51%.
