Object:To set up the method of content determination of ginsenosides Rg1 in Qingnao oral liquid.Methods:HPLC
mobile phase:Acetonitrile-0.4%H3PO4 solution (19∶81)
detection wavelength:205nm.Results:The standard curve was linear in the range of 0.32~3.52μg.The average recovery rate and RSD were 100.8% and 2.39%.Conclusion:This method is accurate
reliable and provides a scientic index for controlling the qualities of Qingnao oral liquid.
