Zhu-mei Xu

Abstract

Objective:To establish a method for the determination of the content of cinnamaldehyde in Sanhan Huoxue plaster.Method:HPLC was used,the mobile phase was methanol-water(60:40),the flow rate was 1.0 mL·min~(-1) and the detection wavelength was 285 nm.Results:The linear range of cinnamaldehyde was 0.047- 0.236μg;the average recovery was 98.5%.Conclusion:The method has a good separation,the results are accurate and reproducible.
