Abstract
The objective of present study was to compare essential oil components of Salvia forskahlei L. collected from nature and cultivated. Experiment materials were collected from Zonguldak province (in Turkey) and cultivated in Faculty of Agriculture of Ankara University. Essential oil components were analyzed by GC-MS. According to results, there were significant differences in terms of essential oil content and components of Salvia forskahlei. The essential oil content varied from 0.01 to 0.10 %. The essential oil components varied depending on climatic and geographic factors. Thirteen components in Salvia forskahlei were determined in nature and germacrene D and β-caryophyllene were the main components of essential oil, representing 19.4 % and 23.6 %, respectively. Germacrene D (29.2 %), α-cadinol (21.2 %) and δ-cadinene (20.5 %) were the major components at first, second and third cutting of 2008, respectively.
