Antibacterial Activity of Some Plant Extracts

Abstract

Ten aqueous and one ethanolic extracts from medicinal plants used in Turkey were evaluated for antimicrobial activity. Plant extracts were prepared using distilled water and 50 % ethanol. It was found that three plant extracts from the 9 plants studied had antibacterial activity. These activities were produced by the aqueous extracts of Pistacia, Tilia argentea and Anthemis pungens. All of these plant extracts had antibacterial activity against E.coli. Also, Tilia argentea and Pistacia spp inhibited the growth of Bacillus subtilis. In addition to these bacteria, Klebsiella pneumoniae, Staphylococcus aureus and environmental Aeromonas spp. strains were inhibited by Tilia argentea.
