Background
This study aimed at investigation of the chemical composition, antimicrobial activity, and antioxidant properties of clove, cumin, origanum, and anise Essential Oils (EOs).Methods
Chemical compositions of the EOs were identified using Gas Chromatography/Mass Spectrometry (GC/MS). The antibacterial activities of EOs against four important food-borne bacteria were assessed by disc diffusion, agar well diffusion, and broth micro-dilution assays. Evaluation of antioxidant properties of the EOs was carried out by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, β-carotene-linoleic acid bleaching test, and total phenolic contents as well. Statistical analysis of data was performed using SPSS, Inc, Chicago, IL software.Results
Eugenol (69.26%) was the main constituents of studied EOs. Although, all five tested bacteria were sensitive to EOs, but Bacillus cereus and Escherichia coli had the highest and lowest susceptibility to the antibacterial activity of EOs (pConclusion
Clove, cumin, origanum, and anise EOs could be regarded as potential sources of natural antioxidant and antimicrobial agents in Iranian food industries and the best results was belonged to clove EO.Keywords:
