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

DOI: 10.26650/forestist.2019.230519 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.
