摘要
Abstract
Extracting technologies of the polysaccharide of Mudan cortex of primary study were finished with a single factor experiment and the orthogonal experiment in different experimental groups (hotwater and ultrasonic method),the effects of various factors,such as ration of liquid to solid,temperature,extraction time and the grainsize etc.On the producing rate of the polysaccharide of Mudan cortex were compared at given conditions.The optimal conditions with traditional method were:Extraction temperature 80℃,heating time 90 min,the material fluid ratio was 1∶35,grainsize 80 mesh.The optimal conditions with ultrasonic method were:Extraction temperature 80℃,ultrasonic time 25 min,the material fluid ratio was 1∶25,power 200 W,grainsize 160 mesh,under this technological conditions,the thick polysaccharide rate was 13.6%;Compared with traditional hot water extraction method,the ultrasonic method could shorten the time of two-thirds and increase the polysaccharide extraction rate above 46%.关键词
