cinnamon, Ceylon cinnamon, Ceylonzimtbaum, Kaneelbaum

Evergreen tree, up to 10m tall, native to Sri Lanka; bark yields the commercial cinnamon; leaves greenish white abaxially, green and shiny adaxially, ovate to ovate-lanceolate, very stiff, 10-16cm long, obtuse; flowers yellow-white, ca.6mm, in loose somewhat silky panicles which often exceed the leaves; fruit ovoid, 10-15mm, black when mature.

The steam-distilled oil of Cinnamomum verum flowers contained (E)-cinnamyl acetate (41.9%), (E)-α-bergamotene (7.9%), and caryophyllene oxide (7.2%).

„The oils of four species of Cinnamomum from Madagascar were studied. C. zeylanicum contained predominantly (E)-cinnamaldehyde together with camphor (15%).“

„The essential oil of the leaves of Cinnamomum zeylanicum Blume from South India was investigated by GC and GC/MS. More than 30 components have been identified with linalool (85.7%), eugenol (3.1%) β-caryophyllene (2.4%), (E)-cinnamaldehyde (1.7%) and α-terpineol as main compounds“

„The leaf oil of Cinnamomum zeylanicum Blume grown in Little Andaman was analysed by GC and GC-MS. Forty-seven constituents, representing 99.96% of the oil, were identified. The main constituents of the oil were eugenol (76.60%), linalool (8.5%) and piperitone (3.31%). The composition of the oil is comparable to cinnamon leaf oil produced in Bangalore and Hyderabad (south India) in terms of eugenol and linalool contents.“

Major constituents of the essential oils identified and quantified by gas chromatography were:
Cinnamon bark: cinnamaldehyde (50.5%), cinnamyl acetate (8.7%), β-caryophyllene (7.5%), 1,8 cineole (5.2%), eugenol (4.7%)
Cinnamon leaves: eugenol (76.9%), β-caryophyllene (3.5%), benzyl benzoate (2.8%), cinnamaldehyde (2.7%), linalool (2.2%)

Concerning the hydro-distilled volatile oil of the buds, α-bergamotene (27.3%) and α-copaene (23.0%) are found as major constituents, followed by α-humulene (6.1%). (E)-cinnamyl acetate (2.4%) was one of the minor components.

The steam-distilled volatile oil from cinnamon fruit stalks contained mainly (E)-cinnamyl acetate (36.5%) and (E)-caryophyllene (22.3%).

„The essential oil yields of the different plant parts were: tender twigs, 0.40%; pedicels of buds and flowers, 0.36%; buds and flowers, 0.04%; pedicels of fruits, 0.33%; fruits, 0.32%. The tender twig oil was richer in α-phellandrene (3.4%), limonene (1.6%) and (E)-cinnamaldehyde (4.0%). The volatile oils from pedicels were richer in neryl acetate (1.4-2.0%), (E)-cinnamyl acetate (58.1-64.5%) and β-caryophyllene (9.6-11.1%). Higher amounts of (Z)-cinnamyl acetate (6.1%), α-humulene (2.2%), δ-cadinene (2.2%), humulene epoxide I (5.0%), α-muurolol (4.9%) and α-cadinol (2.4%) were observed in the oil of buds and flowers. The fruit oil showed greater concentrations of α-pinene (4.2%), β-pinene (1.9%) and linalool (27.4%). However, all the oils contained linalool (3.6-27.4%), (E)-cinnamyl acetate (22.0-64.5%) and β-caryophyllene (6.9-11.1%) as their major compounds.“

„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 essential oil from the bark of C.zeylanicum has excellent antimicrobial effects against various pathogen E. coli strains.
