Optimization of Extraction and Separation Process of Polysaccharide in Zizyphus jujuba Mill

WU Na,ZHU Ao-lan,XU Bao-hong,LI Pei,YANG Jie(College of Life Science and Technology,Xinjiang University,Urumqi 830046,China)  
Objective:To determine the datas in the process of extracting and separating polysaccharides from jujube with hot water and alcohol deposit.Methods:During the extracting process,three main factors such as liquid-solid ratio,extracting time,extracting temperature were studied by single factor test and orthogonal experiments.In the separating process,three main factors such as concented multiple of extracting liquid,the volume of alcohol and the time of deposit were studied by single factor test.Results:The result indicates that the optimal extracting condition were as follows:the ration of liquid-solid 24∶1,extracting duration 6h,extrating temperature 90℃.The optimal separating condition were as follows:the extracting liquid was concentrated 8 times,adding 4 times volume ethanol and deposit 12 hours.Conclusion:The results provided the probability for the processing of Zizyphus jujuba Mill in Xinjiang.
