The aim of the present study was the development and validation of a simple, precise and specific reversed phase HPLC method for the simultaneous determination of coumarin, cinnamyl alcohol, cinnamaldehyd, acid cinnamic, eugenol, cinnamyl acetat, acid 2-hydroxycinnamic in cinnamon. The substances were extracted from the sample matrix with methanol, shaken at room temperature for 30 minutes and determined by HPLC-PDA on the following conditions: column C18 sunfire (250 × 4.6 mm, 5 µm), mobile phase 30mM ammonium acetate and methanol-acetonitrile (50:50) using gradient. The recovery > 90%, the repeatability has RSD < 7.3%, the LODs and LOQs of2-hydroxycinnamic acid, coumarin, cinnamaldehyd, cinnamyl alcohol, eugenol were 1 µg/g and 3.3 µg/g, respectively; the LODs and LOQs of cinnamic acid, cinnamyl acetate were 2 µg/g and 6.7 µg/g, respectively. The method has been applied to analyze the samples.
