Essential wood oil of Cupressus sempervirens varieties (horizontalis and pyramidalis)

18653

The essential oils isolated from the woods of Cupressus sempervirens var. horizantalis and var. pyramidalis harvested from natural and cultivated locations in Turkey were characterized by GC-MS analyses. Fifty-one compounds, representing 91.9-95.7% of the oil composition, were identified. The oils obtained from two varieties wood exhibited quite similar composition. Sapwood and heartwood oils were mainly composed of oxygenated monoterpenes (43.7-72.4%), sesquiterpenoids (8.7-36.5%) and diterpenoids (2.2-10.4%). The major compounds were carvacrol methyl ether (38.2-62.6%), α-cedrol(15.7-34.3%), manool (1.75-9.83%), terpinen-4-ol acetate (0.82-4.15%) and bornylacetate (0.26-4.62%). Compared to other Cupressus species, Cupressus sempervirens wood can be classified as a carvacrol methyl ether rich species. As a result, the wood oil of Cupressus species can be characterized by the presence of two compounds: α-cedrol and carvacrol or carvacrol methyl ether.
