ABSTRACT

 

Abbasvali M, Esmaeili Koutamehr M, Moshtaghi H, Hadi Eskandari M., Effect of leaf extract of olive (Olea europaea) cultivars on Staphylococcus aureus, Onl J Vet Res., 19(8): 519-529, 2015. Activity of acetonic, ethanolic and methanolic leaf extracts of 4 olive cultivars against Staphylococcus aureus as determined by broth micro-dilution assay are described. Area under growth curves were compared with controls and expressed as percentages. Inhibition increased with concentrations of acetone > methanol > ethanol extracts. Acetonic 5 mg/ml and methanolic extracts of 10 mg/ml resulted in 93% inhibition in growth of S. aureus. At 5 mg/ml, extract of Roghani olive cultivar showed highest inhibition in comparison with other cultivars.

 

Key words: Olea europaea, Staphylococcus aureus, Antibacterial effect, olive leaf extract.
