Objective: To determine the content of the paeoniflorin in Qianlie Antong capsule by HPLC. Method: The separation was performed on Waters Nova-Pak C18 (4.6 mm×150 mm
4 μm)column eluted with the mobile phase consisting of acetonitrile-water (15∶85) at the flow rate of 1mL·min-1.The detection wavelength was at 230 nm and the retention time of paeoniforin was 3.757 min. Result: Paeoniflorin showed good linearity(r=0.997 6)in the range of 0.20-4.0 μg.The mean recoveries of low
middle and high concentration of the components were among 97.85%-100.38% (RSD 0.37%-0.81%). Conclusion: The method is rapid
simple
accurate and reliable
and it can be used for determining paeoniflorin in Qianlie Antong capsule.
