Abstract: | Objective:HPLC determination of puerarin in Ganmaoqingre oral liquid.Methods:Using high performance liquid chromatography;Column:Shim - pack VP - ODS column(150mm×4.6mm);The mobile phase:methanol - water (24:76)flow rate:1.0ml/min;detection wavelength:250nm;injection volume;20μl.Results:in the sample volume 0.5μg~4μg within the puerarin peak area and sample volume showed good linear relationship between the regression equation is:A = 48895170.86C +4178.18;r = 0.999996 The average recovery was 98.98%RSD = 0.55%.Conclusion:The method is simple,rapid,accurate and reproducible. |
