摘要
利用超声波法提取青钱柳多糖,研究了超声时间、超声功率、料液比对青钱柳多糖得率的影响,并采用正交试验对青钱柳多糖提取工艺进行优化设计。结果表明,超声波法提取青钱柳多糖的最佳条件为:超声时间70 m in,超声功率1 200 W,料液比1∶10。超声功率和超声时间对提取青钱柳多糖的影响分别为显著差异和极显著差异,因此利用超声波法提取青钱柳多糖可以缩短提取时间,提高得率。
Ultrasonic wave was applied in extraction of polysaccharide from Cyclocarya paliurus （Batal） Ijinskaja . The effects of ultrasonic power, solid- liquid ratio, ultrasonication time on extraction efficiency were studied. Based on single and orthogonal experiments, the optimum conditions were established as follows： ultrasonic power 1 200 W, extracting time 70 minutes, solid to liquid ratio 1： 10. Analysis of variance showed that the effects of ultrasonication time and ultrasonic power on extraction polysaccharide are statistically significant and highly significant, respectively.
