Congress Abstract

we investigated, antibacterial activity of essential oil of different parts (stem and leaves) of Satureja bachtiarica Bunge by well diffusion method.

The essential oil tested antibacterial activity against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Shigella dysenteriae and Proteus mirabilis. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were tested against the bacteria. Phytochemical analysis of the essential oil was done.

The essential oil showed antibacterial activity against tested bacteria. The (MIC) for P. aeruginosa were found to be 400µg/ml while for the K. pneumoniae a lower MIC value (200µg/ml) was obtained. The minimum bacterial concentration for the essential oil against all the pathogens tested was 400–500µg/ml.

The number of compounds detected the essential oil extracted from the stem and leaves parts by GC/MS technique, was 20 and the main compounds were:

Carvacrol (48.2%), cis-jasmone (13.1%) and geranyl acetate (4.0%).
