Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a gas chromatography method for the determination of cinnamaldehyde content in the volatile oil of cinnamon twig. The method used an OV-17 chromatographic column, with an injector temperature of 250 ℃, a detector FID 250 ℃, carrier gas He: 1mL/min, H20.2kg/cm2, and air 0.4kg/cm2. The results showed that the peak area of cinnamaldehyde injection had a good linear relationship with the concentration of the tested substance within the concentration range of 0.082~1.640g/L, r=0.9994, and an average sample recovery rate of 100.69%. Acetonitrile was used as the solvent, The content of cinnamaldehyde in volatile oil measured at different time points is relatively similar. Conclusion: This method is simple, accurate, and has good reproducibility
