Abstract:
The aim of this work was to investigate chemical compositions and antibacterial properties of several Iranian essential oils (EO) bearing plants including Satureja hortensis , Trachyspermum ammi , Mentha piperita , Lippia citrodora, and Foeniculum vulgare . Antibacterial properties of EOs against Pseudomonas putida , Enterobacter aerogenes , Salmonella typhi and Escherichia coli as Gram-negative bacteria and also Leuconostoc mesenteroides subsp.mesenteroides , Listeria monocytogenes , Bacillus cereus and Staphylococcus aureus as Gram-positive bacteria were determined by Disk diffusion agar, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC). The chemical composition of EOs was characterized using gas chromatography and gas chromatography/mass spectrometry (GC/MS). The results of EOs analysis indicated that there are different compounds in each EO giving them different characteristics. According to the results, each EO has a different potential to inhibit the growth of bacteria. Among the EOs studied, T. ammi and S. hortensis revealed the strongest antibacterial activity whereas F. vulgare showed the weakest antibacterial activity.
