Antimicrobial Effect of different Extracts of Rosa damascena on E. coli

Introduction: Due to the resistance of microorganisms against antibiotics, the use of medicinal herbs as alternative medicines has become commonplace. The purpose of this study was to explore the antimicrobial effects of aqueous, ethanolic and acetonic extracts of Rosa damascenon on E. coli as one of the most common pathogenic bacteria. Methods: Extraction was carried out using soaking method. To determine the antimicrobial effect of different extracts of Rosa damascenon, Agar diffusion and minimum inhibitory concentration (MIC) methods were employed. Results: The results showed that ethanolic extract has better antimicrobial effect than other extracts. The halo size and the minimum inhibitory concentration for the ethanolic extract of Rosa damascenon were 21mm and M=25μg / ml respectively. The aqueous extract of Rosa damascenon was free of any antimicrobial effect against E.coli. Conclusions: Because of the antimicrobial activity of ethanolic extract of Rosa damascenon, clinical studies can be conducted to illuminate the effectiveness of ethanolic extract of Rosa damascenon in treating infections.
