Cupressus sempervirens var. stricta is cultivated as an ornamental tree (Tuskany, Provence).
Cupressus sempervirens var. atlantica (Cupressus atlantica Gaussen) grews in the central parts of the Atlas Mountains.

Main components of the essential oil of Cupressus sempervirens L. cones, prepared by steam distillation, were α-pinene (48.2%), δ-3-carene (19.0%), terpinolene (3.9%), cedrol (3.3%), myrcene (3.0%), limonene (2.5%), α-terpineol (2.2%), α-terpinyl acetate (2.2%), and α-fenchene (1.8%).

The essential oil of the needles and twigs of var.atlantica is dominated by α-pinene (60%), with cedrol (8%), and limonene (4%).

The essential oil of the needles and twigs of var.stricta was dominated by sabinene (39.6%) and α-pinene (19.3%); main components were also limonene (7.3%), 4-terpineol (7.3%), γ-terpinene (6.1%), α-terpinene (3.9%) and myrcene (3.4%).

Essential oil from plant material collected within 12 months (1999) in the central part of Dalmatia (Croatia) showed α-pinene (28.4-79.2%) as the main component. Other important components were γ-3-carene (9.1-32.6%), α-cedrol (1.2-12.9%), limonene (1.4-8.7%), terpinolene (0.6-7.0%) and α-terpinyl acetate (0.8-4.5%).

The unique warm-woody agrestic-herbal scent of dried C.sempervirens wood is based on carvacryl methyl ether and α-cedrol, rounded off by bornyl acetate, terpinen-4-yl acetate, and further mono-and sesquiterpenes.
The leaf scent (headspace, trees of Bolgheri, Italia) is based on sabinene (13.5%), δ-3-carene (24.4%), limonene (6.8%), terpinolene (7.2%), and α-pinene (6.5%), and characterized by isothujone (0.1%), karahanaenone (1.2%), cis-sabinene hydrate acetate, linalool, linalyl acetate, bornyl acetate, terpinen-4-ol, α-terpinyl acetate, α-cedrol, (3E,5Z)-1,3,5-undecatriene (0.03%, intense galbanum), and (2E,4Z)-deca-2,4-dienyl isovalerate (0.01%, juniper berry-related).
