In vitro antimicrobial activity of Eryngium planum extract against food borne pathogenic bacteria

Background and Aim : Eryngium planum is a member of the Apiaceae family and sub-family of Saniculoidae that is widely distributed in the Europe, America, and southwestern Asia. E. planum exhibit a high degree of pharmacological properties including anti-inflammatory, antinociceptive, antihemolytic, and antimycotic as well as used as a food preservative. The aim of the present study was to evaluate the antimicrobial effect of ethanolic E. planum extract against Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Listeria monocytogenes, Salmonella typhimurium, and Escherichia coli O۱۵۷:H۷ using agar disk diffusion.Methods : The in-vitro antibacterial properties of the ethanolic E. planum extract at concentrations of ۰.۵ and ۰.۷۵% against aforementioned bacteria at ۷ log CFU/ml was evaluated using agar disk diffusion.Results : Based on our findings, the diameter inhibition zone of E. planum extract against investigated bacteria was as follows: S. aureus (۳.۱۱-۳.۵۵ mm) > L. monocytogenes (۲.۱۸-۲.۲۲ mm) > E. coli O۱۵۷:H۷ (۱.۷۶-۱.۸۵ mm) > S. typhimurium (۱.۲۵-۱.۲۷ mm).Conclusion : According to the results of the present study, E. planum extract could be considered as a practical potential strong antimicrobial in food products.
