Title: Determination of the content of paeoniflorin in Dingkun pills by RP-HPLC
Abstract: Objective A high-performance liquid chromatographic method was developed for the determination of the content of paeoniflorin in Dingkun pills. Method A Kromasil C_(18) column(4.6 mm×250 mm ,5 μm) was used, with the mobile phase consisting of acetonitrile-H_2O binary system. The detection wavelength was 230 nm. Results The linear range of paeoniflorin was 3.664~36.64 mg·L~(-1), r = 0.999 7(n = 5); the average recovery was 99.6%(n = 9), RSD was 1.0%. Conclusion The method is simple and can be used to determine paeoniflorin in Dingkun pills with satisfactory accuracy and reproducibility.
