Objective:To determinate the content of vitexin in Xinan Capsules by RP HPLC.Methods: C 18 ODS(4.6mm×150mm;5μm) column with temperature at 25 °C was used with a mobile phase of water zspropanol acetic acid(75∶18∶3) elution at the flow rate of 1mL -1 ·min -1 and detection wavelength at 330nm.Results: The linear range of vitexin was from 0.734 to 3.67 μg, and correlation coefficient was 0.9996 . The content of vitexin in Xinan Capsules is 9.7%. Conclusions:The detection method is simple and convenient, accurate with a good reproducibility. The extraction method of the control sample is simple, and easy to do.
