antibacterial activity of the essential oils from five endemic herbs (lamiaceae)

background & aim: the major aim of this study was to determine the antibacterial activity of the essential oils from five medicinal plants. experimental: the hydro-distillation essential oils from five plant species, including satureja bachtiarica, zataria multiflora, thymus daenensis, thymus carmanicus, and ziziphora tenuior (lamiaceae) which are endemic in iran. in-vitro antibacterial test was done by agar disc diffusion and serial dilution assays. results & discussion: most of the essential oils indicated relatively antibacterial activity against the tested bacteria with the diameter of inhibition zone ranging between 7 and 33 mm. recommended applications/industries: the essential oils from iranian herbs could be used as natural antimicrobial agents in food preservation.
