Abstract :
Aim and Background: The aim of this study was to evaluate and compare the antibacterial activity of Elettaria cardamomum, Urtica dioica L, Valeriana officinalis and Crocus sativus extracts on Staphylococcus aureus and Escherichia coli. Material and Methods: After preparing the spices first aqueous extracts are prepared based on the dry weight of the extract in different concentrations were prepared by means of diffusion in agar and development of wells in a minimum inhibitory concentration of the dilution Micro MBC plates was studied. Results: Also, the inhibitory effect of MBC and MIC of Aqueous mixture were also determined. Accordingly Crocus sativus extract has the highest antibacterial effect and Elettaria cardamomum extract has the least effect on both Gram-positive and Gram-negative antibacterial, though antibacterial effect on gram-positive bacteria were all extracts. Discussion: Medicinal plants can have antimicrobial effects as a medicinal supplement and have less side effects than using them. Discussion: Medicinal plants can have antimicrobial effects as a medicinal supplement and have less side effects than using chemical drugs.
