Chemical composition and Antimicrobial Activity of the Algerian Laurus nobilis Essential oil

The aim of this research is to determine the chemical composition and the antimicrobial activity of Algerian Laurus nobilis essential oil. The chromatographic analyses (CG/MS) have shown that the major components of Laurus nobilis essential oil are the 1.8 cineol (24,658%) and the linalol (18,563%). The Laurus nobilis essential oil has shown an antimicrobial activity against all the tested strains except the Pseudomonas aeruginosa which shown a strong resistance. The Minimum Inhibitory Concentrations (MIC), Minimum Bactericidal Concentrations (MBC) and Minimum Fungicidal Concentrations (MFC) have been determined by the agar dilution method, some micro-organisms were susceptible to the essential oils that have the MBC values between 1% and 0.03%. A fungicidal action has been obtained regarding the Candida albicans, a fungistatic one regarding the Saccharomyces cerevisiae, these results promise to get a scientific validation to the massive use of this species
