摘　　要：采用索氏提取器提取黄秋葵果荚多糖,研究料液比、提取时间、乙醇体积分数3个因素对黄秋葵多糖提取量的影响,采用L9(33)正交试验确定最佳提取工艺参数。结果表明,与常规热浸提法相比,索氏提取法具有节省资源的优点,其最佳提取工艺参数为:提取料液比为1∶100,提取时间为2 h,乙醇溶液体积分数为15%,黄秋葵多糖的得率为7.05%。Soxhlet extraction was used to extract polysaccharide from okra. The effect of ratio of solid to liquid, extraction time and ethanolvolume fraction on extraction efficiency of polysaccharide were analyzed. Orthogonal experiment design L9 （3^3） was applied to optimize the extraction parameters. The results showed that the more resources were saved by soxhlet extraction. The ratio of solid to liquid of 1：100 andethanol volume fraction of 15% for 2 h were the optimal extraction parameters. The best extraction efficiency of polysaccharides from okra was obtained for 7.05%.
