ABSTRACT
Objective To established a method for the content determination of ginsenoside Rg1 in Yushangling Capsules by HPLC. Methods HPLC was used with the C18 column. The mobile phase was acetonitrile-0.5% phosphoric acid (24∶76). The flow rate was 1.0 mL/min, the column temperature was 25 ℃, and the detection wave was set at 205 nm. Results The calibration curve was linear in the range of 0.05~0.80 ?g. The regression equation was Y =3629375.5X+2517.1, r =0.9998. The average recovery was 100.48% and RSD was 1.59%. Conclusion The method is simple, accurate and suitable for the content determination of ginsenoside Rg1 in Yushangling Capsules.
