Coarsely ground cinnamon(Cinnamomum zeylanicum)was extracted using supercritical CO2in commercially available equipment. The extracts were made at 50°C with pressures varying from 300–600 bar. The extracts were compared chemically with a methylene chloride oleoresin and a water-distilled oil. It was found that the chemical composition between all of the materials was very similar. The cinnamaldehyde and eugenol contents varied from 75.72% to 83.19% and 1.57% to 2.40%, respectively. From this study, it can be concluded that for supercritical CO2extraction of cinnamon at 500C, pressures greater than 300 bar are not necessary.
