摘　　要：本文从椭圆叶花锚中提取多糖,经过水提工艺可以提高椭圆叶花锚的综合利用率.采用热水提取椭圆叶花锚多糖,从液固比、提取温度、提取时间3个方面对得率进行考察.结果发现水提椭圆叶花锚多糖的最佳提取条件的液固比为10∶1,浸提温度为80℃,浸提时间1.5h最为理想.在此条件下,多糖得率为2.3%.该优化工艺对椭圆叶花锚中多糖的进一步研究具有一定的参考价值.to improve [ Objective the compre The research aimed extract polysaecharide from Halenia eUiptica D. Don. ensive utilization rate of Halenia eUiptica D. Don. [ Method ] Hot water was employed as extracting agent. Three factors, including ratio of liquid-solid, temperature, and time were investigated. [ Result ] Optimum conditions for extraction was as follows：the ratio of liquidsolid was 10： 1, temperature was 80℃, and time for extraction was 1. Sh. Under the optimum conditions, the extraction ability of polysaeeharides in Halenia was 2. 3%. [ Conclusion ] The optimized technology could provide reference for the further study of polysaceharides from Halenia elliptica D. Don.
