[Study on the extraction process of polysaccharide from Lycium barbarum].
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.


CONCLUSIONS
The experimental results provide the basis for the water extration process of polysaccharide from Lycium barbarum L.
