Study on the extraction process of polysaccharide from lycium barbarum L.

Zhang Que

Abstract

Objective: To choose the optimum extraction process of polysaccharide from lycium barbarum L.. Methods: The yield and the content of polysaccharide were respectively used to evaluate the factor levels. The optimal water extraction process was selected with the orthogonal design. Results: The ideal extraction process was: the polysaccharide was extracted with water for 3 times, with solvent volume 6 times amount each time, extraction time 8 h each time. Conclusion: The ex-perimental results provide the basis for the water extraction process of polysaccharide from lycium barbarum L.
