Abstract Satureja is belonging to the family Lamiaceae. Satureja bachtiarica Bunge. is one of the endemic species. In this study, aerial parts of S. bachtiarica were colleted in full flowering stages from six populations of Fars Province and after were dried in laboratory conditions, the essential oils (EOs) and extracts were obtained by hydrodistillation and macetation methods. Chemical compositions of the EOs were analyzed by GC-FID and GC-MS and the phenolic contents were determined by HPLC analysis. EO yields were from 1.1 to 2.4 % (w/w) based on dried material. The major constituents of the EOs were thymol ( 10.9-49.8 %), carvacrol (1.1-49.7 %), p-cymene (18.0-32.8 %), γ-terpinene (4.3-7.5 %), linalool (3.3-5.1 %) and caryophyllene oxide (1.6-2.3 %). Among six populations, the EOs from the Kohanjan and Abadeh-Didegan populations had the highest thymol and carvacrol amount (49.8 and 49.7 %), respectively. Narengenin, carvacrol, hesperedin, eugenol, hesperetin, rosmarinic acid and thymol were the main phenolic copmounds in six studied regions. These results showed that variation of ecological characters had effect on quality of S. bachtiarica EOs and extracts.
