Abstract
This study was conducted to determine the essential oil compositionand diurnal variations (9.00 am, 12.00 am and 16.00 pm) of Sideritistrojana Bornm. which was distributed naturally at the peak ofKazdağı (Edremit-Balıkesir), west of Turkey during the growingseason. The oil composition was determined with GC-MS. Thehighest quantity of essential oil content (0.25-0.30%) was found atthe full plant flowering stage and the lowest was at fresh fruitingstage (0.07-0.1%). Diurnal fluctuation in essential oils of whole plantwas also observed. The highest and lowest essential oil levels wereobserved at the afternoon (16.00 pm) and in the morning (08.00 am),respectively. The oils were consisted of mainly α-bisabolol (27.8%),valeranone (13.4%), 4-terpineol (10.3%), germacrene-D (8.8%) andspathulenol (5.8%) during vegetative stage, 4-terpineol (30.3%),caryophyllene (21.0%) and 3-methyl nonane (9.3%) during floweringstage, 4-terpineol (16.1%), copaene (15.4%), caryophyllene (10.6%), 3-methyl nonane (9.8%) and valeranone (7.9%) during fresh fruitingstage.
Özet
Bu araştırmada, Kazdağları’nda (Edremit-Balıkesir) yayılış gösteren Sideritis trojana Bornm türünün uçucu yağ oranı ve bileşenlerinin diurnal ve ontogenetik varyasyonunun belirlenmesi amaçlanmıştır. Uçucu yağ bileşenleri GC-MS analizi ile yapılmıştır. En yüksek uçucu yağ oranı çiçeklenme döneminde (%0.25-30), en düşük uçucu yağ oranı ise meyve döneminde %0.07-0.10) tespit edilmiştir. Uçucu yağ bileşenleri vejetatif dönemde esas olarak; α-bisabolol (%27.8), valeranone (%13.4), 4-terpineol (% 0.3), germacrene-D (%8.8) ve spathulenol (%5.8); çiçeklenme döneminde ise 4-terpineol (% 30.3), caryophyllene (%21.0) ve 3-methyl nonane (9.3%); meyve oluşumu döneminde 4-terpineol (%16.1), copaene (% 15.4), caryophyllene (%10.6), 3-methyl nonane (%9.8) ve valeranone (%7.9) olarak belirlenmiştir.
