| Abstract: | Objective] The test was carried out to study the extraction technology of water-soluble crude polysaccharide from Dioscorea opposita Thunb.cv.Tiegun.Method] Taking total polysaccharide content as investigation index,on the basis of single factor test,extraction technology condition of water-soluble crude polysaccharide from Dioscorea opposita Thunb.cv.Tiegun was optimized by orthogonal test.The extracting crude polysaccharide was purified preliminarily.Result] The optimum technology condition was 1∶20 material-water ratio,extracting under 100 ℃ for 3 h and settling under 90% ethanol system.The total polysaccharide content reached 1.40% under the former situation.Conclusion] This study offered references for the further research and development of Dioscorea opposita Thunb.cv.Tiegun. |
