Abstract
Objective: The extraction technique of the polysaccharide on Ruoqiang Jujube is studied and the extraction methods was compared in this paper.Methods: Several factors,e.g.water volume,temperature,time and extraction times affect the polysaccharide on Ruoqiang Jujube extraction rate,the extraction conditions are optimized by the method of orthogonal design,and the optimum condition is determined.Results: The optimal conditions for hot water extraction was 1∶16 of the ratio of sample to water,240minutes of extraction at 100℃ and one time; The optimal conditions for enzyme extraction was pH4.5,60minutes of extraction at 60℃ and 0.03% concentration of enzyme;The optimal conditions for alkali extraction was Na2CO3,1∶20 of the ratio of sample to water,180minutes of extraction at 80℃.Conclusion:The optimize extraction methods was enzyme extraction,the second was alkali extraction and the last was hot water extraction.
