Determination of Cinnamaldehyde in Guizhi Fuling Drop Pills by RP - HPLC / 中国药房

ABSTRACT

OBJECTIVE:To determine the content of cinnamaldehyde in Guizhi fuling drop pills by RP - HPLC. METHODS:The determination was performed on Symmetry C_(18)(150 mm?4.6 mm,4?m) with the mobile phase consisted of acetonitrile 0.1%phosphoric acid solution(21:79) at a flow rate of 1.0 mL?min~(-1).The detection wavelength was set at 284 nm.RESULTS:The linear range of cinnamaldehyde was 4～40?g?mL~(-1)(r =0.999 8) with an average recovery of 99.39% (RSD = 1.22,n = 9).CONCLUSION:The established method is simple,accurate,precise and applicable for the quality control of Guizhi fuling drop pills.
