Objective: Objective To determine the content of harpagoside in granules of Yangyin Qinfei. Method: A Rp-HPLC method was established . The chromatographic column was Hypersil ODS(4.6 mm×250 mm)
and acetonitile-water (containing 1%acetic acid ) (15 ∶85~60 ∶40 )(0~25 min ) was wsed as mobile phase. The flow rate was 1 mL ·min-1
the detection wavelength was at 278 nm
and the column temperature was 25 ℃. Result :The average recovery of harpagoside was 97.02%
and RSD was 0.6%(n=9). Conclusion: The method established can be used to determine the content of Harpagoside in Granules of Yangyin Qinfei.
