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.
