Abstract:To establish HPLC fingerprint method for quality control of saponins in Rhizoma Panax Japonicus.Methods:The HPLC method was conducted based on a Hibar C18(4.6 mm×250 mm,5 μm) column,with acetonitrile-0.1% orthophosphoric acid as mobile phase by gradient elution.The detection wavelength was at 203 nm.The flow rate was 1.0 mL·min-1 and the column temperature was 30 ℃.Seven samples from different sources were analyzed by HPLC.Results:Twelve main marker peaks were selected in the standard fingerprint and 7 peaks of saponins were identified.The similarity of 6 samples was over 0.9.Conclusion:The precision,repeatability and stability of the method were up to standard,and this method can be used for quality evaluation of Rhizoma Panax Japonicus.
