The harvested plants were dried in the shade and the essential oil contents were determined by Clevenger apparatus by hydro distillation and analyzed by GC-MS. The highest content of essential oil was obtained at 18.00 hours with 2.96% and the lowest one’s was obtained at 12.00 hours with 2.20%.The main components of the essential oil were determined as carvacrol (23.29% - 39.89%), thymol (16.24% - 21.52%) and γ-terpinene (18.01% - 20.90%).
