Essential-oil composition of the Tunisian endemic cypress (Cupressus sempervirens L. var. numidica TRAB.)

Chem Biodivers. 2013 Jun;10(6):989-1003. doi: 10.1002/cbdv.201200045.


The essential oils isolated from leaves, wood, and cones of the Tunisian endemic cypress Cupressus sempervirens L. var. numidica Trab. collected from three natural populations were characterized by GC-FID and GC/MS analyses. In the wood, leaf, and cone oils, 38, 35, and 26 constituents, representing 94.4, 97.8, and 98.5% of the total oil composition, respectively, were identified. Monoterpenes constituted the major fraction of the oils from all organs and for all populations. The oils were found to be of an α-pinene (64.2%)/δ-car-3-ene (11.1%) chemotype with considerable contents of α-humulene (3.4%) in the leaf oil, cedrol (2.8%) in the wood oil, and sabinene (3.2%) in the cone oil, respectively. α-Pinene, δ-car-3-ene, limonene, carvacrol methyl ether, α-humulene, and α-amorphene were the main components that differentiated the oils of the three organs in the cypress of Makthar.
