Objective: To establish HPLC method for the simultaneous determination of sinomenine and psoralen in Longzuan Tongbi granule. Method: The contents were determined by HPLC method on Phenomenex Gemini C18 column (4.6 mm×250 mm
5 μm); with methanol-0.1%triethylamine (47.5:52.5) as the mobile phase; the flow rate was 1.0 mL·min-1; and the detection wavelength was set at 246 nm. Result: Sinomenine and psoralen showed good linear relationship within 1.01-12.12 μg (r=0.999 7) and 0.024 36-0.292 32 μg(r=0.999 8) respectively. The average recovery rate was 100.49%(RSD 3.0%) and 97.00%(RSD 1.9%). Conclusion: The method is rapid
simple
reliable
and accurate
and can be used as the quality evaluation method for Longzuan Tongbi granule.
