摘要
[目的]对超声波-微波协同提取沙棘(Hippophae fhamnoides L.)多糖的工艺进行优化。[方法]采用单因素试验考察了提取时间、微波功率和料液比对沙棘多糖得率的影响,采用正交试验确定了最佳工艺参数,并与水提法、微波法和超声波法的提取效果进行对比研究。[结果]超声波-微波协同提取沙棘多糖的最佳工艺条件为:提取时间180s,微波功率450W,料液比1∶30(W/V),在此最佳工艺条件下,沙棘多糖得率最高为22.50mg/g。[结论]超声波-微波协同提取沙棘多糖优于水提法、超声辅助法以及微波法。
[Objective]The study aimed to optimize the ultrasonic-microwave synergistic extraction technique of polysaccharide from Hippo-phae fhamnoides L..[Method]The effects of extraction time,power of microwave and the ratio of liquid to solid on the yield of polysaccharide were explored by single-factor experiment,and the optimum technique parameter was determined by the orthogonal test.And then the extraction effect of the method was compared with that of water extraction,microwave assisted extraction and ultrasonic assisted extraction.[Results]The optimal technique conditions for the ultrasonic-microwave synergistic extraction were：the extraction time 180 s,power of microwave was 450 W and the ratio of solid to liquid 1∶30,under these conditions,the highest yield of polysaccharide from Hippophae fhamnoides L.was 22.50 mg/g.[Conclusion]The ultrasonic-microwave synergistic extraction is better than other extraction methods.
