Abstract

Objective To establish the quantitative method of ginsenoside Rg1 and Re in Youganning capsule by RP-HPLC.Method Samples were analyzed on ODS C_(18) column.The mobile phase consisted of acetonitrile-0.05%H_3PO_4(19.7∶80.3) eluted in gradient mode.UV detector was set at wavelength of 203 nm.Result The assay was linear over the range of 1.06-10.60 μg for ginsenoside Rg1 and 0.848-8.48 μg for ginsenoside Re.The average recovery was 100.09% with RSD of 2.15%(n=6).Conclusion This method is rapid,sensitive and reproducible for the quality control of Youganning capsule.
