Abstract

A method for the determination of the content of cinnamaldehyde in Rouguiyou cataplasma was established.HPLC was used with a DiamoonsilC18(2)(4.6mm×250mm,5μm),the mobile phase was acetonitril-water-acetic acid(50:5:0.3),the flow rate was 1.0 mL·min-1 and the detection wavelength was 290nm.The linear range of cinnamaldehyde was 1.4625~46.8μg /mL,and the average recovery was 98.12%.The results were accurate and reproducible,and the method was suitable for the determination of cinnamaldehyde in Rouguiyou cataplasma.
