摘　　要：目的:比较3种不同溶剂对五味子中多糖提取效率的影响。方法:采用单因素实验确定碱水法和醇碱法提取五味子多糖的最佳工艺,并与文献报道水溶剂提取法做了比较,测定3种溶剂最佳工艺条件下的多糖得率。结果:醇碱法对五味子多糖的提取率最高,为水提法得率的1.12倍,碱水法得率的1.06倍。结论:醇碱法是一种效率高、稳定可行的五味子多糖提取方法。AIM： To compare three different solvent extraction procedures affecting the extraction rate of polysaccharide from Schisandra chinensis （ Turcz. ）. METHODS： We used single factor experiments, optimized the extraction process of polysaccharide from Schisandra chinensis （ Turcz. ） by alkali solution and ethanol-alkali solu- tion, respectively, and contrasted the two methods with the water extraction method that had been reported, determined the extraction rate of polysaccharide by optimum condition of three kinds of solvent. RESULTS： These resuits showed that ethanol-alkali extraction procedure had the highest extraction rate, 1.12 times more than water extraction procedure and 1.06 times more than alkali extraction procedure. CONCLUSION： Ethanol-alkali extraction procedure is a high effective and stable for polysaccharide from Schisandra chinensis （Turcz.）.
