Essential Oil Constituents of Cnidium silaifolium (Jacq.) Simonkai Grown in Different Locations in Lakes Region, Turkey

This study was carried out in 2014 in order to determine the fruit essential oil content and components of Cnidium silaifolium (Jacq.) Simonkai, which grow naturally in different locations in the flora of Goller Region, Turkey. The essential oils of fruits were obtained by hydro-distillation and components of the oils were identified by gas chromatography/mass spectrometry. The essential oil contents of fruits from Aksu (1.120 m) and Dedegol (1.540 m) locations were 0.50% and 0.65%, and the numbers of components forming essential oils were 38 and 29, respectively. Major components of the oils in both locations were β-Elemene (22.30-29.79%), Trans-Caryophyllene (11.85-21.88%), Germacrene-D (9.74-17.31%), α- Humulene (5.22-5.85%) and δ-Cadinene (4.82-6.66%). In the study, it was found that altitude had a significant effect on essential oil components and their proportions, and some components at low altitude were not found at high altitudes.
