| Abstract: | Objective RP-HPLC method was developed for determining the assay of Andrographolide in Chuanxinlian Tablets.Methods RP-HPLC was used.The analytical column was a YWG-C 18(250mm×4.6mm, 10μm) column.The mobile phase was water-methanol (50∶50).The flow rate was 1.2ml·min -1 ,and the UV detection wavelength was 225nm.Results The aver age recovery of the method was 99.4%(n=5).Conlusion The proposed method can be used in the qu antitative analysis of Andrographolide.The method is convenient,economic al and accurate with good reproducibility. |
