Title: Chemical composition, antimicrobial and antioxidant activities of the essential oil of Rosmarinus Officinalis L, cultivated in Fes-Meknes region
Abstract: In the aim of the valorization of the medicinal plants of Morocco, we have chosen to study the Rosmarinus officinalis a very potential plant, belong to the Lamiaceae family to evaluate its antimicrobial and antioxidant activities. The leaves of Rosmarinus officinalis cultivated were collected from the region Fes-Meknes and had been dried for 15 days away from light. The volatile compounds obtained by hydrodistillation of this plant were analyzed by a gas chromatograph coupled with a mass spectrometer (CG/MS), 34 compounds were characterized, with α-pinene, Levoverbenone, Bornanone, D-Limonene, Camphene as the major compounds, the evaluation of the total antioxidant activity of this essential oil using the phosphomolybdanum method. The Rosmarinus officinalis has many uses in traditional therapy and known by its antiseptic proprieties against the infectious disease of bacterial origin, therefore we have studied the effect of this essential oil against four microorganisms in the aim to evaluate the antimicrobial activity, we have used two gram-negative bacteria ( Escherichia coli , Salmonella), one gram-positive ( Staphylococcus aureus) and one opportunistic pathogenic yeast ( Candida albicans ), the Minimum inhibitory concentrations (MIC) were determined by microdilution method, the results confirm that this essential oil presented antimicrobial activity against microorganisms tested. The essential oil of Rosmarinus officinalis can be used for improving the quality and shelf life of food products.
