Abstract: 

Today over than 22000 strains of Salmonella were investigated. Species of medicine resistance were presented due to consuming of Antibiotic in Animals. Genus of Satureja with the Persian name of “Marzeh” consists of 15 species in Iran, 9 of them (S. bachtiarica, S. edmondi, S. sahendica, S. kallarica, S. rechingeri, S. intermedia, S. isophylla, S. atropatana, S. khuzistanica) are endemic. In this research anti-microbial effect and chemical composition of the essential oils of these plants were investigated. The aerial parts of S. bachtiarica, S. edmondi and S. mutica were collected at full flowering stage from habitats in Yazd, Khorassan and Kermanshah provinces, respectively. The plant materials were hydro-distilled in order to obtain their essential oils. The oils were analyzed by capillary GC and GC/MS. The results showed the oil yields of S. bachtiarica, S. edmondi and S. mutica were %2.15, %2.31 and %1/0, respectively. Carvacrol (%66.5) and p-cymene (%15.2) were characterized in the oil of S. bachtiarica samples. In the oil of S. Mutica, carvacrol (%30.9); thymol (%26.5), gamma-terpinene (%14.9) and p-cymene (%10.3) were the main constituents. In the oil of S. edmondi p-cymene (%61.1), gamma-terpinene (%9.6) and thymol (%5.0) were the main constituents. For study of anti-microbial effect of the oil samples, the oils was diluted by DMSO at %2.5 and %5 and tested against two kinds of Salmonella paratyphi (A and B) by disk diffusion method. The results of three replicate showed, the oil by concentration of %2.5 and %5 inhibited the growth of Salmonella paratyphi A at 8 & 11mm (S. bachtiarica), 8 & 10 mm (S. mutica) and 7 & 11 mm (S. edmondi) and inhibited the growth of Salmonella paratyphi B at (9 & 11)mm, (8 & 12)mm and (6 & 12)mm respectively. The results showed the high anti-microbial effect of these oils. It seems the presence of thymol, carvacrol, P-cymene and gamma-terpinene in these oils caused the strong anti microbial effect of them.
