ABSTRACT
Objective To set up a method for the determination of ginsenoside Rg1 in Changyu Granules. Methods The content of ginsenoside Rg1 was determined by RP-HPLC on C18 column (4.6 mm?250 mm, 5 ?m). The mobile phase consisted of ethane nitrile and water (8020). The flow rate was 1.0 mL/min. The detection wavelength was at 210 nm. Results Ginsenoside Rg1 showed a good linear relationship at the range of 0.125~4 ?g, r =0.999 7. The average recovery rate was 97.30%, RSD=1.31%. Conclusion The method is simple with good reproducibility, and can be used for the quality control of Changyu Granules.
