| Abstract: | Objective: To select the optimum extraction procedure for polysaccharide from rhizoma polygonati by water extraction and alcohol precipitation (WEAP) . Method: The optimum extraction procedure was selected with the content of rhizoma polygonati by orthogonal test design. Result: The optimum extraction procedure was determined with 8 times of water decocting 1. 5h and 4 times, and the polysaccharide was precipitated with 4 times alcohol. Conclusion: The optimum extraction procedure was simple, reliable and the extracting ratio was high. |
