?eftali (Persica vulgaris Miller) yaprak ekstrakt?n?n antibakteriyel etkisi

摘要

Aim. In our study we aimed to determine antibacterial effect of peach leaves extract. Methods. In Erzincan Horticultural Research Institute Gen Garden varietes seven cardinal peach’s (Persica vulgaris Miller (Rosaceae) tree leaf methanol extract was used for this purpose, Antibacterial effect was evaluated by cutplug method whereas minimum inhibtory concentration (MIC) was determined by microdilution method. Results. In this study peach’s (Persica vulgaris Miller ) leaf extract antibacterial effect on Staphylococcus aureus, Staphylococcus aureus (MRSA) was not determined, on the other hand the antibacterial effects on Escherichia coli, Escherichia coli O:157 H:7, Proteus mirabilis, Proteus vulgaris, Salmonella enteritidis, Salmonella typhimurium, Streptococcus pyogenes, Enterococcus faecalis, Staphylococcus epidermidis, Klebsiella pneumoniae, Listeria monocytogenes, Micrococcus luteus, Pseudomonas aeruginosa, Bacillus cereus, Bacillus subtilis, Yersinia enterocolitica was determined. The lowest minimum inhibitory concentration on Pseudomonas aeruginosa and Yersinia enterocolitica detected as (0.01 mg/mL), the higest concentration on grup of Bacillus subtilis, Escherichia coli, Escherichia coli O:157 H:7, Salmonella enteritidis, Salmonella typhimurium, Staphylococcus epidermidis, Streptococcus pyogenes was determined as (10 mg/mL). Conclusions. As a result of our study peach’s (Persica vulgaris Miller) leaves extract spectrum showed broad antibacterial effect. Starting from such plants, thought to be started the process of the formation of new antibacterial agents.
