Objective: To establish an HPLC method for the simultaneous determination of swertiamain and swertisin in herba Lomalogonium rotatum. Method: Swertiamain and swertisin were simultaneously analyzed using HPLC accompanied with Phenomenex C18 (4.6 mm×250 mm
5 μm) column and UV detector. Methanol-water was chosen as the mobile phase with gradient elution. The wavelength was set at 237 nm
while the flow rate was set at 1.5 mL·min-1. Result: Swertiamain and swertisin were linear within the range of 0.27-5.40 mg (r=0.999 8)
0.165-3.3 mg (r=0.999 6)
respectively. Meanwhile
the average recoveries were 98.49% (RSD 1.06%) and 97.35% (RSD 1.45%)
respectively. Conclusion: The method is simple
rapid
accurate and possesses good reproducibility. It can be used for the quality control of Lomalogonium rotatum.
