Determination of ginsenoside in Yixin Capsule by HPLC / 中成药

AIM: To establish an analytical method of determining ginsenoside in Yixin Capsule by HPLC. METHODS: Ginsenoside Rg_1 and ginsenoside Re in the capsule were separated by HPLC on C_(18) column(250 mm?4.6 mm) with a CH_3CN-0.05 mol/LH_3PO_4(22∶78) as a mobile phase and detected at 203 nm.The flow rate was 1.0 mL?min~(-1). RESULTS: There was a good linear relationship in a range of 1.066-6.396 ?g for ginsenoside Rg_1 and 0.904-5.424 ?g for ginsenoside Re.The average recoveries were 97.1% and 97.3% respectively. CONCLUSION: The method is accurate,rapid and simple for quantitative analysis of Panax Ginseng in Yixin Capsule.
