摘要
以桑枝为试材,采用微波法,进行了微波功率、微波时间及固液比对多糖得率单因素影响试验;在此基础上,采用响应面法对各提取条件进行了优化,以期筛选桑枝多糖的最佳工艺条件。结果表明:最佳提取工艺为微波功率400W、微波时间6min、固液比1∶20(g∶mL),桑枝多糖得率达到2.81%。表明微波提取法是一种适宜桑枝多糖提取的方法。
Taking Morus alba as material,the effect of microwave power,microwave time and solid to water ratio on the yield of polysaccharides from Morus alba were studied by microwave method.On the basis of that,the response surface method was used to optimize the extraction conditions in order to get the best microwave extraction technology.The results showed that the optimum conditions were：microwave power 400 W,extraction time 6 min,solid to liquid ratio 1∶20 g/mL,the yield of polysaccharides could reach 2.81%.So microwave method was a suitable method for extraction of Morus alba polysaccharides.
