| Abstract: | Objective：To establish and compare the methods for the content determination of polysaccharides in Radix Adenophorae. Method：The polysaccharides were isolated and extracted from Radix Adenophorae by water extraction and alcohol precipitation. The standard curve of polysaccharides from Radix Adenophorae was obtained with glucose as the control.The content of polysaccharides was determined by anthrone sulphuric acid colorimetry and phenol-vitriolic colorimetry using a UV spectrophotometer.Result：The content determined by anthrone-sulphuric acid colorimetry was 16.37%with average recovery of 101.1%（RSD =2.1%）,and that determined by phenol-vitriolic colorimetry was 15.26%with average recovery of 99.9%（RSD = 1.8%）.Conclusion：Both methods for the content determination of polysaccharides in Radix Adenophorae are reliable and accurate,and can be considered as the assay methods for polysaccharides in Adenophora tetraphylla（thunb.） Fisch. |
