 +The striking feature of the tree cinnamon (bark/leaf/root bark) oils is their different main component, this being cinnamaldehyde in bark oil, eugenol in leaf oil, and camphor in root bark oil. Oils from Sri Lanka contained cinnamaldehyde (bark oil, 74%), eugenol (leaf oil, 87%), and camphor (root bark oil, 60%) e.g. (Wijesekera et al. 1974). \\

-"The volatile oil of the bark of Cinnamomum zeylanicum was extracted by means of supercritical CO2 fluid extraction in different conditions of pressure and temperature. Its chemical composition was characterized by GC-MS analysis. Nineteen compounds, which in the supercritical extract represented >95% of the oil, were identified. (E)-Cinnamaldehyde (77.1%), (E)-β-caryophyllene (6.0%), α-terpineol (4.4%), and eugenol (3.0%) were found to be the major constituents. The SFE oil of cinnamon was screened for its biological activity about the formation of melanin in vitro. The extract showed antityrosinase activity and was able to reduce the formation of insoluble flakes of melanin from tyrosine. The oil also delayed the browning effect in apple homogenate. (E)-Cinnamaldehyde and eugenol were found to be mainly responsible of this inhibition effect." \\+"The volatile oil of the //bark// of Cinnamomum zeylanicum was extracted by means of supercritical CO2 fluid extraction in different conditions of pressure and temperature.
