The family Lamiaceae is represented by 45 genera, 546 species and 730 taxa in Turkey. The genus Origanum is represented in Turkey by 24 species, the ratio of endemism in the genus is 63 %. Origanum vulgare subsp. hirtum Ietswaart collected from different localities in Marmara region and their cultivated forms provided from Atatürk Central Horticultural Research Institute Yalova I Turkey were subjected to hydrodistillation to yield essential oils which were subsequently analysed by GC and GC/MS. The main constituents of the oils were identified and antimicrobial bioassays were applied. The analyses showed that wild and cultivated Origanum vulgare subsp. hirtum oils included carvacrol obtained from wild plants and from cultivars (82.9 -7.5 % and 85.4 – 5.3 % respectively), and included thymol from wild and from cultivars (60. 1-0.3 % and 68.0 – 0.3 % respectively) as main components. The essential oils showed strong antimicrobial activity against ali microorganisms tested except some microfungi.
KEY WORDS: Origanum vulgare subsp. hirtum I Lamiaceae I Essential oil/ GC/MS analysis / Antibacterial activity I Antifungal activity I Carvacrol I Thymol.
