摘要
以艾叶为原料,采用超声波-酶法提取多糖。通过正交优化实验获得最佳工艺条件为:料液比1∶40、超声波提取时间30min、乙醇浓度80%,艾叶多糖提取率为0.790%。与超声波法提取艾叶多糖相比,超声波酶法艾叶多糖的实际得率提高56.75%。
Based on the orthogonal experiment,the optimum extraction conditions of polysaccharides from argy wormwood leaves were obtained through ultrasonic-enzyme.The results showed that the optimum extraction conditions of polysaccharides were as follows：ratio of material solvent 1：40,extraction solvent 80% ethanol concentration,ultrasonic extraction time 30min.Under such condition,the extraction rate was up to 0.790%.Polysaccharides and ultrasonic extraction of the leaves compared to the actual yield of ultrasonic leaves polysaccharide increased 56.75%.
