摘　　要：目的:优化南五味子多糖的提取条件。方法:采用正交实验设计,以南五味子多糖提取率为考察指标,考察提取时间(extraction time)、固液比(solid-liquid ratio)和浸泡时间(immersion time)对多糖提取率的影响。结果:实验表明南五味子多糖提取所需的最优时间为40 min,浸泡最佳时间为90 min,固液比为1:25,在此条件下南五味子多糖提取率较高。结论:优选出的最佳提取条件,实验证实结果稳定,方法可行,为南五味子多糖的进一步研究提供参考。Objective：To optimize the extraction condition for polysaccharide of Fructus Schisandrae Sphenantherae. Methods：The extraction technique was designed by orthogonal test with extraction time, solid-liquid ratio and immersion time as factors using extraction rate as index. Results：The optimum conditions for the ultrasound-assisted method to extract polysaccharide were as follows： extraction time was 40 min, solid-liquid ratio was 1 ： 25, immersion time was 90 min. Conclusions： The optimum process is feasible, stable and reasonable. It provides reference for the further study of the polysaccharide of Fructus Schisandrae
