Objective:To choose the optimum extration process of polysaccharide from Lycium barbarum L Methods:The optimal water extration process is selected with the orthogonal design The yield and the content of polysaccharide were used to evaluate the factor levels Results:The ideal extraction process is:the polysaccharide is extracted with water for 3 times,with solvent volume 8 times amount each time (10 times amount for the first time), extraction time 1 h each time and stired 10 min each hour Conclusion:The experimental results provide the basis for the water extration process of polysaccharide from Lycium barbarum L
