Gaertn., A. incana (L.) Moench, and A. viridis (Chaix) DC. extracts JF - Journal of Health Sciences JA - JHSCI VL - 6 IS - 2 SE - Research articles DO - 10.17532/jhsci.2016.328 UR - https://www.jhsci.ba/ojs/index.php/jhsci/article/view/543 SP - 100-104 AB - <p><strong>Introduction: </strong>The objective of the present study was to evaluate the antimicrobial and cytotoxic activities of water extracts of leaves and barks from <em>Alnus glutinosa </em>(L.) Gaertn., <em>A. incana </em>(L.) Moench, and <em>A. viridis</em> (Chaix) DC.</p><p><strong>Methods: </strong>The antimicrobial activities of extracts were tested against gram-negative and gram-positive bacteria as well as yeast strains by the agar diffusion method. The cell viability was determined by the Trypan blue dye exclusion method.</p><p><strong>Results: </strong>The largest diameters of inhibition zone (DIZ) were recorded with <em>Staphylococcus aureus </em>ATCC 6538 and <em>Bacillus subtilis</em> 168M. The highest percentage of cell viability was observed with water bark extracts of <em>A. glutinosa </em>(97.46%).</p><p><strong>Conclusions: </strong>Potential antimicrobial properties of <em>A. glutinosa</em>, <em>A. incana</em>, and <em>A. viridis</em> demonstrated in this study, as well as their low levels of toxicity, make them an interesting subject for further studies.</p> ER -
