Essential oils (EOs) of three Apiaceae species, including Bunium persicum, Cuminum cyminum and Carum copticum, extracted by hydrodistillation were analyzed by gas chromatograph (GC) and GC/mass spectrometry. The main components of Eos of B. persicum were γ-terpinene (44.2%), cuminaldehyde (16.9%), γ-terpinen-7-al (10.5%), and ρ-cymene (8%). The major constituents of Cu. cyminum were cuminaldehyde (30.2%), ρ-cymene (14.1%), γ-terpinene (12.8%), and safranal (9.4%), while those of Ca. copticum were thymol (48.4%), ρ-cymene (21.8%) and γ- terpinene (21.3%). The antibacterial effects of the EOs were assessed on several food-borne pathogens, namely Staphylococcus aureus, Bacillus cereus, Escherichia coli O157:H7, Salmonella enteritidis, and Listeria monocytogenes. The ranges of minimum inhibitory concentration (MIC) of the oils were 0.03- 0.5, 0.18-3.0, and 0.37-3.0 mg/ml, respectively, for Ca. copticum, B. persicum and Cu. cyminum. Moreover, the combination of B. persicum and Cu. cyminum EOs confirmed synergistic and additive activities against the pathogens.
