摘要：The chemical composition and antibacterial activity of the essential oils of Lavandula pedunculata and Lavandula dentata collected in south of Morocco, were investigated. The essential oils were isolated by hydrodistillation and analyzed by GC and GC-MS. The minimal-inhibitory concentration (MIC) of the essential oils was evaluating the antibacterial activity against different strains, gram negative bacteria Escherichia coli (ATCC 4157) and Pseudomonas aeruginosa (ATCC 27853) and Gram positive bacteria Staphylococcus aureus (ATCC 25923) and Streptococcus fasciens (ATCC 29212). The essentialoils were characterized by a high percentage of oxygenated monoterpenes, the main compounds being camphor for our oils, 53.1% and 50.3% for L pedunculata and dentata respectively. The essential oils of both species exerted significant antibacterial activity against the four bacteria strains. The inhibitory activity of the essential oils in Gram-positive bacteria was significantly higher than in Gram-negative. Our findings demonstrate that the essential oils of L pedunculata and L dentata possess antimicrobial activity.
