ABSTRACT
Background and Aim: In traditional medical sources numerous antibacterial effects of Rosa damascene extract are mentioned. Thus, the present study aimed at assessing the antimicrobial effect of five different synthetic brands of rose water and aqueous extract of the flower in comparison with rose oil
Materials and Methods: Five different brands of synthetic rose water each having concentrations of 1 ,10, 25,50,75,and 100, water extract of Rosa damascene with concentrations of 0.2mg/ml,2mg/ml, 5mg/ml,10mg/ml,15mg/ml, and 20mg/ml and rose oil whose concentrations were 0.1 mg/ml, 1 mg/ml, 2.5mg/ml, 5mg/ml, and 10mg/ml were tested regarding to their antimicrobial activity against Staphylococcus aureus ATCC 29213, Enterococcus faecalis ATCC 29212, Esherichia coli ATCC 25922, Pseudomonas aeruginosa and Candida albicans by broth micro-dilution assay. All bacterial turbidities were examined visually. Each test was repeated three times
Results: In this study, the use of any concentration of rose water failed to inhibit the growth of microorganisms completely. However, it was found that there is a significant difference between increasing of rose water concentration and decreasing the microorganism growth. The minimum inhibitory concentration [MIC] values of water extract of Rosa damascene were 8 mg/ml in Staphylococcus aureus, 6 mg/ml in Enterococcus faecalis and Esherichia coli, and 4 mg/ml in Candida albicans. The MIC values of rose oil were 10 mg/ml in Staphylococcus aureus and Esherichia coli, 5mg/ml in Enterococcus faecalis, 1 mg/ml in Candida albicans. No inhibitory effect of Rose extract and Rose oil on Pseudomonas aeruginosa was found
Conclusion: The current study showed rose water, water extract of rosa damascene, and rose oil have antimicrobial effects. However, clinical use of this finding requires more extensive studies
