Abstract:
Satureja bachtiarica belonging to the family Lamiaceae is an endemic plant that widely distributed in southwestern of Iran. In this study, antibacterial activity and chemical composition of the essential oils from wild populations of S. bachtiarica collected from the alpine regions of southwestern of Iran were evaluated. The essential oils obtained from the aerial parts of ten populations of S. bachtiarica were analyzed by GC-FID and GC-MS. Essential oil yields were from 1.5 to 1.9 mL/100 g dried material. The major constituents of the essential oils were carvacrol (1.26–62.3 %), thymol (3.2–40.6 %), γ-terpinene (1.94–28.3 %), and p-cymene (6.6–18.4 %). The essential oils from S. bachtiarica were rich in monoterpenoids, especially oxygenated monoterpenes. Among ten populations, the essential oils from the Mehriz and Yazd populations had the highest carvacrol amount (62 %). Results indicated that the essential oils had moderate-to-good inhibitory activities against six bacteria. In total, two chemotypes, including carvacrol and thymol were determined for S. bachtiarica .
