【Abstract】 Aim To select the optimum extracting procedure for polysaccharide from cordyceps sinensis. Methods The optimum extracting procedure was selected with the content from cordyceps sinensis by orthogonal test design. Reslts The optimum extracting procedure was determined with 10 times of water decocting 0.5 h and 3 times, and the solution were concetrated to 0.5 g cordyceps sinensis per milliliter andrecipitated with 67% alcohol. Conclusion The optimum extracting procedure was simple, resonable and reliable.更多还原
