Objective To establish a HPLC method for the determination of ginsenoside Rg1 in Shuxiong dropping pills.Method The content of ginsenoside Rg1 in Shuxiong dropping pills was determined on Kromasil C18 column by HPLC.The mobile phrase was acetonitrile-water(22∶78).The flow rate was 1 mL/min with UV detection wavelength at 203 nm.Results A good linear for ginsenoside Rg1 was in the range of 33.1~220.4 μg/mL(r=0.9991).The average recovery(n=6) was 97.2%
RSD=1.3%.Conclusion The HPLC method is simple
reliable
accurate and can be used for the determination of ginsenoside Rg1 in Shuxiong dropping pills.
