This study aimed to investigate the antibacterial activity of essential oils and methanol extracts of Ziziphora tenuior on some pathogenic bacteria in culture and determination of its minimal inhibition concentration (MIC) and minimal bactericidal concentration (MBC).
The results showed that the MIC for essential oils of Ziziphora tenuior was 250 mu g/ml for most of the gram negative bacteria except for Pseudomonas aeruginosa. The gram-negative bacteria Klebsiella pneumoniae was more sensitive compared to other species of gram-negative bacteria. On the other hand, the MIC of gram-positive bacteria such as Staphylococcus aureus was 250 mu g/ml, and for other species of Staphylococcus it was 500 mu g/ml. The results of the MIC determination of the methanol extracts of this plant showed that the combination of these has inhibitory and bactericidal effect on all bacteria under test except for Pseudomonas aeruginosa. The MBC of the methanol extract of Ziziphora tenuior was 2000 mu g/ml for most of the gram-negative bacteria and less for the gram-positive ones. We can conclude that low concentrations of the essential oils of this plant are able to inhibit the growth of the bacteria under study.
