Abstract

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.
