Objective To establish an HPLC-DAD method for simultaneous determination of vitexicarpin, ferulic acid, puerarin, and paeoniflorin in Yiqi Congming Pills. Methods HPLC analysis was performed on Waters X-bridge C18 column(250 mm×4.6 mm, 5 μm)with acetonitrile-0.5% phosphoric acid solution by gradient elution. The detection wavelength was set at 257 nm (vitexicarpin), 315 nm (ferulic acid), 251 nm (puerarin), and 230 nm (paeoniflorin). The flow rate was 1.0 mL/min, the column temperature was 25℃, and the sample volume was 10 μL. Results Vitexicarpin, ferulic acid, puerarin, and paeoniflorin showed good linear relationships in concentration range 0.098-9.830, 0.199-19.900, 0.239-23.900, and 0.237-23.700 μg/mL, respectively. The recoveries were 99.57%, 99.64%, 99.13%, and 99.64% with values of 1.79%, 1.35%, 0.67%, and 1.43%, respectively.Conclusion The method is simple, fast, accurate, and reliable, and can be applied to the quality control of Yiqi Congming Pills.
