The Lycium barbarum polysaccharides(LBP) were extracted by the traditional extraction method and method of ultrasonic extraction and the contents and yield of the polysaccharides extracted with those two kinds of methods were analyzed.The result showed that,the yield of LBP from Ningxia lyceum extracted with traditional method was 7.87%,and 9.41% from Jinghe,Xinjiang Lyceum;but the yield of LBP from Ningxia Lyceum extracted with ultrasonic method was 8.61% and 13.77% from Jinghe Lyceum. The results also showed that extraction efficiency of ultrasonic extraction was higher than that of traditional extraction.The utilization ratio of active constituent of medicinal materials can be increased in comparison with the traditional method.Also the yield of Lycium polysaccharide from Jinghe extracted with the same method was higher than that of Ningxia Lycium.
