Abstract

Objective To determine cinnamaldehyde in Xueyujingang Capsules.Methods RP-HPLC method was used. The samples were separated on a Alltima C 18 column with the mobile phase of acetonitrile-0.1% phosphoric acid(48∶52) and the detection wavelength was set at 288 nm.Results The calibration curves were linear at the range of 43.32～639.12 ng for cinnamaldehyde(r=0.999 94).The average recoveries of cinnamaldehyde were 101.2% (RSD=1.5%).Conclusion The method is quick,accurate and suitable for the determination of cinnamaldehyde in Xueyujingang Capsules and capable to control its quality.
