Özet

Thymus migricus is an endemic and highly biodiverse plant species belonging to the Lamiaceae family. This

plant is often found in mountainous areas, especially on limestone grounds. The species is adapted to arid and

semi-arid climates, especially in high mountain regions. Morphologically, T. migricus is generally recognized

by its small-sized, densely hairy leaves and characteristic essential oil glands. Studies on the biochemical

composition of T. migricus have highlighted the pharmacological potential of the plant. In particular, the leaves

and flowers of T.migricus have been identified as a rich source of antioxidants, polyphenols and essential oils.

These components may support the plant's antioxidant, anti-inflammatory, and antimicrobial properties. There

have been some reports of Thymus migricus being used in Van herbed cheese, tea, and for traditional medicinal

purposes in Eastern Turkey and Iran. In this study, Thymus migricus was collected from Erzincan Dumanlı

Nature Park. The aerial parts of plant material were freshly used for essential oil isolation. The fresh aerial

parts (400 g) were cut into small pieces and subjected to hydro distillation using a Neo-Clevenger-type

apparatus in 2-liter deionized water and maintained for 2 hours. The hydro distillation process was carried out in

triplicate. Decanted and dried over Na2SO4 essential oils were kept at +4 °C in sealed dark vials. The analysis

was performed using the Thermo Scientific GC-MS instrument. Total 38 components, representing 99.25% of

the total oils were identified. Main components of the oil were determined as carvacrol (46.91 %), thymol

(18.06 %), p-cymene (9.17%) and γ-terpinene (6.14%). Antimicrobial susceptibility tests were applied to 7

pathogenic bacterial strains with these extracts. Imipenem was used as a positive control. Inhibition zones was

measured as 35 mm for Pseudomonas aeruginosa, 18 mm for E.coli, 40 mm for Bacillus cereus, 41 mm for

Clostridium perfringens, 39 mm for Listeria monocytogenes, 35 mm for Staphylococcus aureus, and 28 mm for

Salmonella enteritidis. A strong antibacterial effect was observed in all 7 strains tested. Essentials oils of

Thymus migricus appears to have potential applications in the pharmacology and food industries.
