Studies on the lethal effects of plants on harmful microorganisms have made them an important and valuable
resource for health. Turkey, wherefore the junction center of three phytogeographic regions, is home to
numerous medicinal and aromatic plants with its rich flora. In this study, antimicrobial activity of hexane,
ethylacetate, methanol and water extracts of aerial parts of L. canescens, which has known as “Topajdarbaşı”
in Turkey, was investigated. Plant samples were collected from Pöske Mount in Erzincan. Antimicrobial
activities of extracts were evaluated using disc diffusion method against Gram-negative bacterias (Pseudomonas
aeruginosa, Klebsiella pneumoniae, colistin-resistant Escherichia coli, Escherichia coli) and Gram-positive
bacterias (Enterococcus faecalis, Staphylococcus aureus, Streptococcus pneumoniae). To conclude, hexane,
ethylacetate and methanol extracts of L. canescens showed considerable antimicrobial activity against S.aureus,
E.faecalis, S.pneumoniae strains.
