Objective To study the optimum preparation procedure for extracting polysaccharide contained in Schisandra chinensis. Methods Selecting factors with decoction degree, water multiple, temperature, and polysaccharide content in extraction liquid as investigation index by orthogonal design, the optimum preparation procedure for extracting polysaccharide of Schisandra chinensis is chosen. Results The optimum condition for extracting from Schisandra chinensis is decoction for 4h ,25 double water and 100℃. Conclusion We can obtain the optimum preparation procedure for extracting polysaccharide from Schisandra chinensis through orthogonal examination.
