【 摘 要 】

The essential oils (EOs) of six plants (Artemisa herba alba,Rosmarinusofficinalis,Ocimum basilicum,Lavandula officinalis,Mentha viridisandMenthapiperita) widely distributed in Morocco were isolated and their chemical composition was investigated by gas chromatography-mass spectrometry (GC/MS). These EOs were testedin vitroagainst four pathogenic bacterial strains (Enterococcus faecalis,Escherichia coli,Klebsiella pneumoniaeandStreptococcus D) and we determined the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of each EO. The oils of various plants showed high activity against all tested bacteria (MIC≤10 µL/ml), of whichK. pneumoniaewas the most sensitive strain (MIC≤5 µL/ml). In addition, the oil fromM. viridisL. which contained high pulegone concentration (45%) exhibited a very interesting antibacterial activity against all the bacterial strains (MIC 2.5 µL/ml) and (MBC 2.5 µL/ml). The UV-visible study on the release of material absorbing at 260 nm showed significant leakage of cytoplasmic contents, indicating damage to the bacterial cell membrane integrity. Thus, these results indicate that the EOs represent a potential source of natural antibacterial substances that may be used against pathogenic systems.
