| Abstract: | OBJECTIVE To detect the related substances in Potassinm dehydroandrographolide succinate injection by HPLC.METHODS Inertsil ODS-3 column(250 mm×4.6 mm,5 μm)was used.The mobile phase consisted of acetonitrile-2%formic acidwater(7:3).The detective wavelength was 251 nm and the column temperature maintained at 35 ℃.RESULTS Principal component and related substances could be completely separated.The relative corrections factor of impurity 1 and impurity 2 were 0.92,0.90,and the relative retention times of impurity 1 and impurity 2 were 0.8,0.9,respectively.The limit of quantitation was 0.2 μg·mL~-1.CONCLUSION The method is sensitive,specific,accurate. |
