Objective To develop a HPLC method for determining the content of riparsaponin in Homonoia riparia Lour. Methods The determination was performed on the HYPERSILBDS-C
18
(200 mm×4.6 mm
5 μm) with mobile phase consisted of acetonitrile-water (75∶25) at a flow rate of 1.0 ml/min. The detection wavelength was set at 203 nm
the column temperature was 30 ℃, and the column pressure was 10.0 MPa. Results There was a good linear relationship for riparsaponin over the ranges of 5 to 500 μg/ml (r=0.999 8). The average recovery was 99.44%
and RSD was 0.52% (n=15). Conclusion The method has good reproducibility and high precision. It can be applied in quality control of Homonoia riparia Lour.
