Region of Turkey. This species traditionally has been used in traditional medicine, to treat

various ailments and infectious diseases. The aim of this study was to compare the chemical

composition the essential oil that was obtained from Satureja spicigera in different

developmental stages in Central Black Sea Region, Turkey. Plant material was harvested at

three different phenological stages (pre- flowering, full- flowering and post- flowering period) of

the life span of the Satureja spicigera. The essential oil of S. spicigera was obtained by

hydrodistillation and analyzed by gas chromatography-mass spectrometry. The hydrodistillation

of aerial plant that were collected at pre- flowering, full- flowering and post- flowering period

resulted in essential oil yields of 0.64%, 1.17% and 0.12%, respectively. Thirty-six compounds

representing 90.83–97.81% of the oils were characterized. Throughout the growth stage of the

plant, the main components were found to be carvacrol (32.77-49.11%), thymol (3.04 –

13.21%), γ-terpinene (3.11-13.33%) and ısothymol methyl ether (3.65-11.98%). While carvacrol

content decreased during vegetation period, isothymol methyl ether level increased. Thymol and

γ-terpinene reached that its highest values during full-flowering stage. The results obtained from

this study showed differences compared to pre-flowering, full-flowering and post- flowering

period on essential oil composition.
