Objective To develop an HPLC method for determination of paeoniflorin in Fufang Chishao Granula. Methods The separation was performed on a Waters C18 column (250 mm× 4.6 mm, 5μm) with acetonitrile-water (30∶70) as the mobile phase at the flow rate of 1.0 mL/min. The detection wavelength was set at 230 nm. Results Paeoniflorin showed good linearity (r=0.999 9) in the range of 0.266-5.32 μg, and the average recovery was 98.00%, RSD=2.22%. Conclusion The method is convenient, sensitive, accurate and repeatable. It can be applied to determination of paeoniflorin in Fufang Chishao Granula and control the quality of the preparation.
