Abstract

Background and Objectives: Medicinal plants have many therapeutic properties including antimicrobial effects with minimum side effects. The purpose of this study was to investigate the antibacterial effects of alcoholic extracts of three medicinal plants; ROSMARINUS OFFICINALIS, HYPERICUM PERFORATUM, and CARTHAMUS TINCTORIUS on the GROWTH CURVE of E.COLI O157. This strain is one of the most dangerous bacteria among gasterointestinal pathogenic micro-organisms.Material and Methods: Leaves and dried flowering branches of rosmary, hypericum and carthamus were used for preparing various concentrations (0.2, 0.3 and 0.4 gr/ml) of alcoholic extracts. The antibacterial effects of these extracts against E.COLI O157 were investigated utilizing well assay technique and spectrophotmetery.Statistical analysis was carried out by analysis of variance (ANOVA).Results: At the first three hours of the experiment, alcoholic extraction of rosmary had an inhibitory effect at all three concentrations comparing to the other two extracts. The hypericum extract showed the least effect at this stage. However, after the first stage of treatment, the reverse results were observed so that E.COLI O157 had the lowest growth rate at the presence ofhypericum extract.Conclusion: Based on the findings of this study, rosmary extract had a stronger antimicrobial effect and the other two extracs did not have substantial antibacterial effect on E.COLI O157 although, inhibition zones were previously determined. Further investigations in this regard may shed more light on the field of clinical applications af medicinal plants for treatment of infectious diseases.
