Objective:To develop an HPLC method for determination of nitidine chloride from Toddalia asiatica.Methods: The determination was performed on a Diamonsil C18 column(250 mm×4.6 mm
5 μm).Acetonitrile-water-0.2% monobasic sodium phosphate(30∶40∶30)was used as the mobile phase.The flow rate was 1.0 mL·min-1.The UV detection wavelength was set at 328 nm.Results:The calibration curve of nitidine chloride was in good linearity over the range of 0.03~0.48 μg(r=0.999 9).The average recovery was 99.33% and the RSD was 3.30%(n=5).Conclusion:The method is accurate
simple and reproducible
and can be used to control the quality of Toddalia Asiatica.
