Objective To determine the content of dehydroandrographolide succinate in Potassium Sodium Dehydroandroandrographolide Succinate Injection by HPLC. Methods The determination was performed on the Agilent C18 column with acetonitrile - 0. 05 mol / mL potassium dihydrogen phosphate(35 : 65 ) as the mobile phase at a flow rate of 1. 0 mL / min and the detection wavelength of 251 nm. Results Dehydroandrographolide succinate in the range of 40 - 400 μg / mL showed the good linear relation with the peak area, the av-erage recovery rate was 98. 39% , RSD = 0. 7% ( r = 0. 999 9,n = 9) . Conclusion This quality control method can effectively control the quality of dehydroandrographolide succinate in Potassium Sodium Dehydroandroandrographolide Succinate Injection, which is simple with accurate results and high sensitivity.
