Investigation of antibacterial activity of Paeonia peregrina L., Salix babylonica L. and Salix alba L. plants

In this study the antibacterial effects on Bacillus subtilis ATCC 6633, Escherichia coli ATCC 25922, Enterecoccus faecalis ATCC 29212, Staphylococcus aureus ATCC 29213, Staphlococcus epidermidis ATCC 12228 and Salmonella typhimurium ATCC 14028 strains were investigated by using the extracts prepared from the leaves, branches and roots of the Paeonia peregrina L. plant, leaves and shell of young branches of Salix alba L., Salix babylonica L. plants and ethanol, methanol, acetone, hexane, distilled water, chloroform, ethyl acetate extracts. It was investigated by using disc diffusion method. Paeonia peregrina L. leaf extracts showed high antibacterial activity on S. aureus bacteria and a broad spectrum antibacterial effect on test bacteria was detected. Antibacterial activity of Salix alba L. extracts were determined on S. epidermidis and E. coli bacteria. Salix babylonica L. extracts showed limited antibacterial effect.
