چکیده مقاله:

Background and Aim:Nowadays, secondary metabolites of medicinal plants are investigated well and assigned antibacterial properties of most of the plant extracts. One of the most common ways to keep foodstuff from spoilage is using of preservatives. Moreover the prevention of microbial contamination in food, these materials help to increase in shelf-life of fruits, vegetables and processed food. On the other hand, anomalous applying of chemical drugs has resulted in microbial resistence development. Plants and their derivatives have potentials to be used instead of chemicals while their side effects are less.Methods:Hydro-alcoholic extract of Falcaria vulgaris was used. The extracts were prepared in different dilutions (240, 120, 60, 30, 15, 7.5 and 3.75 mg/ml) and applied on Escherichia coli and Staphylococcusaureus by Macro-broth dilution and Disk-diffusion methods. Tetracycline and distilled water were used as positive and negative control, respectively. Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) were determined.Results:The extract prevented from E. coli growth in 240 mg/ml. So, MIC is reported equivalent to 240 mg/ml for this bacterium. Although, 240 mg/ml is reported as MBC. About S. aureus, Falcariavulgaris in 240 and 120 mg/ml dilutions could prevent from its growth. Thus, 120 mg/ml is considered as MIC and 240 mg/ml is calculated as MBC. In Disk diffusion method, no inhibition zone was observed in any of the bacteria.Conclusion:The results achieved in this study showed that Falcaria vulgaris extract has growth inhibitory impact on both E.coli and S. aureus and S. aureus is known as more sensitive than E. coli.
