摘　　要：目的:建立紫萁贯众中总多糖的含量测定方法,比较不同产地和采收期紫萁贯众多糖含量。方法:采用硫酸-苯酚法显色,分光光度法在490nm处测定。结果:12个不同产地紫萁贯众多糖含量为1.22%～1.85%,同产地不同采收期紫萁贯众多糖含量为0.91%～1.37%。结论:紫萁贯众多糖含量因产地和采收期变化而不同。Objective：To establish the method for determination of polysaccharide from Rhizoma of Osmunda japonica and the content of polysaccharide from Rhizoma of O. japonica in different locations and different harvest times was compared. Method：Sulfuric acid-phenol method was used and the sugar content was determined by the spectrophotometer at 490 nm. Result：The content of polysaccharide from Rhizoma of O. japonica in different locations was 1. 22% -1. 85% and in different harvest times was 0. 91% -1. 37%. Conclusion：The different locations and different harvest times would affect the content of polysaccharide from Rhizoma of O. japonica.
