摘要
使用微波辅助提取技术,通过单因素实验和L9(34)正交试验对多糖提取工艺进行了优化,并与常规热水提取法进行比较。结果表明:以水为溶剂,青钱柳多糖提取的最佳工艺为:提取功率为1400 W,提取时间为30 min,料液比质量体积1 g∶20 mL,提取得率为2.55%,;与常规提取法相比,微波辅助提取法具有提取时间短、提取率高等优点。
In this manuscript, the microwave-assisted extraction technology for Cyclocarya paliurus (Batal) Ijinskaja polysaccharide was studied by single factor and orthogonal experiments. The results indicated that the optimal extraction conditions were microwave power 600 W, extraction time 30 min, the ratio of sample to water1 : 20 ,and the extraction rate is 2. 55%. Compared with that of the traditional water extraction method, microwave-assisted extraction exhibited the advantage of higher extraction rate, and less extraction time.
