Contribution To the Evaluation of The Antimicrobial Activity of Essential Oils Extracted from Mentha Pulegium and Laurus Nobilis

Abstract

The extensive use of antibacterial agents in human medication has led to the appearance of resistant microbial strains, hence the importance of directing research towards new molecules, where a good part of scientific research is currently directed towards the way of the use of active biological extracts of medicinal plants, in particular towards essential oils.In this context, the objective of this work is to evaluate the antibacterial activity of essential oils extracted from Mentha pulegium and Laurus Nobilis on some pathogenic bacterial species such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa. The extraction of essential oils from aromatic plants: Mentha pulegium, Laurus Nobilis is carried out by the hydrodistillation technique.The results reveal that Mentha pulegium and Laurus Nobilis show a yield of 2.7% and 0.79% respectively. Our results indicate that the two essential oils Mentha pulegium and Laurus Nobilis have very low activity against Escherichia coli, Staphylococci aureus, Pseudomonas aeruginosa, which represent inhibition diameters of 6 mm; 4mm and 2mm respectively. The bacterium Pseudomonas aeruginosais the most resistant to the two essential oils extracted from Mentha pulegium, Laurus Nobilis.
