Anti-bacterial interactions Rosemary (Officinalis rosmarinus) and essential oils of lavender (Lavandula stoechas) on two Gram-positive and three Gram- negative bacteria in vitro

The aim of this study was to investigate the effects of lavender and rosemary essential oil has antibacterial. Essential oil sample after drying in the shade, to hydrodistillation using a Clevenger apparatus were isolated. The antibacterial effects of Han dilution preparation were evaluated by disc diffusion method. In order to standardize the method of antibiotic disks and ATCC bacteria were used. Results showed that the interactions between plants and diluted in a dilution of 1, 2/1 and 4/1 deterrent effect of lavender plants on five different bacteria than the rosemary plant more meaningful. As the diameter of growth inhibition compared the interactions between bacteria and dilution of the plant showed the highest inhibitory effect on oil dilution 1 is P.mirabilis Comparison of the effects of essential oils of lavender and rosemary together on five different bacteria showed that dilution of 1, 2/1 and 4/1 lavender oil P.mirabilis maximum inhibitory effect on bacteria other than its deterrent effect Rosemary plant was the most significant. Determination of MIC and MBC of lavender and rosemary essential oils showed a bacteriostatic effect on bacteria than similar E.fecalis .The bactericidal effects on all bacteria, but bacteria S.epidermis essence is the same. Evaluation of disk diffusion method in comparison with antibiotic discs, the effect of the plant compared to gentamicin disk Streptomycin against five strains of five different bacteria showed. The results of this study and other studies show that the essence of medicinal plants can be used instead of chemical drugs to treat the infection.
