Antimicrobial Activity Of Essential Oils Of Bubonium Graveolens (forssk.) And Anvillea Radiata (coss.)

Essential oils are a group of secondary metabolites identified in several families of aromatic plants. These natural products are distinguished by their chemical characteristics and their interesting biological activities (inflammatory, antioxidant, antibacterial, insecticides,...). It is in this context articulates our work aims to study the antimicrobial activity of essential oils of two endemic medicinal plants of the Southwest Algerian: Bubonium graveolens Forssk (Tafs), Anvillea radiata Coss (Nogd), testing their antibacterial effect on four bacterial strains: Escherichia coli, Pseudomonas aeruginosa, Bacillus steorothermophilus and Staphylococcus aureus. At the concentrations studied, both species manifested significant antibacterial property with a zone of inhibition more than 11 mm noted for Pseudomonas aeruginosa by the effect of the essential oil of Bubonium graveolens.
