摘要

Present study aims to evaluate antimicrobial and antioxidant activities of the crude methanolic extract and different fractions of the <i><span style="font-family:Verdana;">Epilobium</span></i> <i><span style="font-family:Verdana;">roseum</span></i> <span style="font-family:Verdana;">(Schreb). The extract and fractions were used against pathogenic bacteria (</span><i><span style="font-family:Verdana;">Bacillus</span></i> <i><span style="font-family:Verdana;">subtilis</span></i><span style="font-family:Verdana;">, </span><i><span style="font-family:Verdana;">Bacillus</span></i> <i><span style="font-family:Verdana;">atrophaeus,</span></i> <i><span style="font-family:Verdana;">Klebsiella</span></i> <i><span style="font-family:Verdana;">pneumonia</span></i> <span style="font-family:Verdana;">and </span><i><span style="font-family:Verdana;">Pseudomonas</span></i> <i><span style="font-family:Verdana;">aeruginosa</span></i><span style="font-family:Verdana;">) and fungal strains (</span><i><span style="font-family:Verdana;">Aspergillus</span></i> <i><span style="font-family:Verdana;">niger</span></i><span style="font-family:Verdana;"> and </span><i><span style="font-family:Verdana;">Aspergillus</span></i> <i><span style="font-family:Verdana;">flavus</span></i><span style="font-family:Verdana;">).
