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.
