Abstract:
Objective To establish the method for content determination of total flavonoids and polysaccharides in Radix Codonopsis Lanceolatae from Mount Taishan.MethodsThe content of the total flavonoids was determined by UV spectrophotometry and the polysaccharide content was measured with the phenol-sulphuric acid method.ResultsThe optimal detective wavelength was 510nm for the total flavonoids.Satisfactroy linear relationship with the Absorbability was achieved when the mass concentration of rutin was within a range of 8～48?g/ml(r=0.9986).The average recovery rate was 99.31%(RSD=1.82%,n=5).The optimal detective wavelength was 490nm for the polysaccharides.There was good linear relationship between the Absorbability and the content of glucose in a range of 5～50?g/ml(r=0.9964) with an average recovery of 99.12%(RSD=1.49,n=4).ConclusionThis method is sensitive,simple and accurate,and it can be used for the quality control of Radix Codonopsis Lanceolatae from Mount Taishan.
