An Investigation on the Determination of Diurnal and Ontogenetic Variations of Essential Oil Composition in Sideritis trojana Growing in Kazdağı (Edremit-Balıkesir)
Abstract
This study was conducted to determine the essential oil composition and diurnal variations (9.00 am, 12.00 am and 16.00 pm) of Sideritis trojana Bornm. which was distributed naturally at the peak of Kazdağı (Balikesir-Edremit), west of Turkey during the growing season. The oil composition was determined with GC-MS. The highest quantity of essential oil content (0.25-0.30 %) was found at the full plant flowering stage and the lowest was at fresh fruiting stage (0.07-0.10 %). Diurnal fluctuation in essential oils of whole plant was also observed. The higher and lower essential oil levels were observed at the afternoon (16.00 pm) and in the morning (08.00 pm), respectively. The oils were consisted of mainly α-bisabolol (27.8 %), valeranone (13.4 %), 4-terpineol (10.3 %), germacrene-D (8.8 %) and spathulenol (5.8 %) at the vegetative stage, 4-terpineol (30.3 %), caryophyllene (21.0 %) and 3-methyl nonane (9.3 %) at the flowering stage, 4-terpineol (16.1 %), copaene (15.4 %), caryophyllene (10.6 %), 3-methyl nonane (9.8 %) and valeranone (7.9 %) at the fresh fruiting stage.
