Abstract:
Objective To establish an HPLC method for the determination of ginsenosides Rg1 and Re in Shenqi Granula.Methods Chromasil C18 column(250 mm?4.6 mm)was used with acetonitrile-0.05% phosphoric acid solution(21∶79)as mobile phase.The flow rate was 1 mL/min and the detected wavelength was 203 nm.Results Ginsenosides Rg1 and Re could be baseline separated with in 30 min.The average recovery rates were 99.60% and 98.5%,corresponding RSD were 1.93% and 2.31% for ginsenoside Rg1 and Re,respectively(n=5).Conclusion This method is fast and accurate and can be used for quality control of Shenqi Granula.
