Antimicrobial effects of essential oils of medicinal and aromatic plants on human pathogens

In this study, essential oils obtained from plants of Artemisia herba alba, Capparis spinosa, Globularia alypum, Matricaria chamomilla, Ocimum basilicum, Origanum majorana, Peganum harmala, Phagnalon rupestre, Punica granatum peel and Thymus vulgaris collected from natural flora of Libya were isolated from humans and pathogen antimicrobial activities against Enterococcus faecium, Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeroginosa and Staphylococcus aureus bacteria were tested in vitro. The results of the study were consistent with the literature in general and it was determined that the essential oil obtained from the plant Capparis spinosa showed antimicrobial activity against 106 cfu mL-1 dose of Escherichia coli bacteria and the minimum inhibitor concentration (MIC) of 250 μL dose. It has also been shown that many biotic and abiotic factors should be taken into account in these and similar studies to be carried out on the plants by means of the data.
