Abstract Objective To establish an HPLC method for simultaneous determination of Notoginsenoside R1 and ginsenoside Rf in Shenlong Tongluo pills.Methods High performance liquid chromatography was used.Hypersil Hypersil BDS C18(5 μm,4 mm×250 mm) column was selected with acetonitrile-water as the mobile phase for gradient elution.The flow rate was 1.0 ml/min,detection wavelength was 203 nm and the column temperature was set at 35 ℃.Results The linear ranges of Notoginsenoside R1 and ginsenoside Rf were 0.198-9.535 μg (r=0.9993) and 0.957-38.392 μg(r=0.9997) respectively.The average recoveries were 99.10%(RSD=1.57%,n=6) and 98.76%(RSD=2.13%,n=6)respectively.Conclusions This HPLC method was accurate,reliable and reproducible,which can contribute to formulating the quality standard of Shenlong Tongluo pills.
