Özet:

The essential oils isolated from the woodsof Cupressus sempervirens var. horizantalis and var. pyramidalis harvested fromnatural and cultivated locations in Turkey were characterized by GC-MSanalyses. Fifty-one compounds, representing 91.9-95.7% of the oil composition,were identified. The oils obtained from two varieties wood exhibited quitesimilar composition. Sapwood and heartwood oils were mainly composed ofoxygenated monoterpenes (43.7-72.4%), sesquiterpenoids (8.7-36.5%) andditerpenoids (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 Cupressusspecies, Cupressus sempervirens wood can be classified as a carvacrol methylether rich species. As a result, the wood oil of Cupressus species can becharacterized by the presence of two compounds: α-cedrol and carvacrol or carvacrolmethyl ether.
