Title: Determination of paeoniflorin in Shuangjin Tongliting capsules by high performance liquid chromatography
Abstract: Objective To develope a method for determining the content of paeoniflorin in Shuangjin Tongliting capsules.Methods High performance liquid chromatography( HPLC) was used with Diamonsil C18( 250 mm × 4. 6 mm,5 μm) chromatographic column. The mobile phase was acetonitrile- 0. 1% phosphoric acid solution( 15 ∶ 85). The detection wavelength was 230 nm. Results The sample size of paeoniflorin showed a good linearity in the range of 0. 163 to 1. 630 μg( r = 0. 9999). The average recovery was98. 71% with RSD of 0. 54%. Conclusion The method is simple,accurate and reproducibile,which can be applied to the quality control of Shuangjin Tongliting capsules.
