ABSTRACT
Objective: To develop an assay for the determination of cinnamaldehyde in Cortex Cinnamomi and Shentai Plaster. Methods: Hypersil C 18 column (200?4.6mm, 5?m) was used. The mobile phase consisted of a mixture of methanol acetonitrile water tetrahydrofuran (25∶15∶55∶5) with a flow rate of 0.8mL?min -1 . The detection wavelength was at 285 nm. Results: The calibration curve was linear in the range of 32~320ng for cinnamaldehyde ( r =0.9995). The average recoveries of cinnamaldehyde in Cortex Cinnamomi and Shentai Plaster were 97.8% (RSD=3.0%) and 92.2% (RSD=2.9%), respectively. Conclusion: This HPLC method is simple, rapid and accurate, and it can be used in the control of product quality and preparation process.
