Abstract:

Qutran (Wood tar) oils and vapor of Olea europaea subsp. cuspidate extracted medicinal plants were screened for their activity against seven strains of bacteria. Bacillus subtilis, methicillin-resistant Staphylococcus aureus (MRSA), Micrococcus, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumonia using agar well diffusion method were investigated. Results showed that the effect of oils extract was higher than that of vapor. The tar oils have great antibacterial activity against all the investigated strains. The growth inhibition rate ranged from 16.33 to 46.00 mm. The wood tar oil showed higher activity against tested organisms than Streptomycin. In this study the most pronouns effect was shown by that of Olea europaea subsp. cuspidata wood tar oil. The most susceptible bacteria were Pseudomonas aeruginosa, flowed by Micrococcus luteus, while the most resistant bacteria were Staphylococcus aureus with 16.33 mm of inhibition zone. The results showed that wood tar oil of Olea europaea subsp. cuspidate was more effective than Streptomycin against. GC-MS analysis revealed that the Qutran (Wood tar) oils contained mainly octadecenamide (5.77%); lucenin 2 (5.46%); docosane and nonacosane (3.75%); cyclopropene (3.50%); hematoporphyrin (2.68%); tetratetracontane (2.36%); dotriacontane (1.57); acetic acid (1.53); N-methylglycine (1.49%) and propyne antimicrobial (1.41%). All identified compounds are known to have antimicrobial activity.
