Chemical composition and antibacterial activities of propolis collected from different regions of Turkey

Abstract

The aim of the present work is to study the chemical composition and antibacterial activities of Turkish propolis collected different regions of Turkey such as Adapazarı, Burdur, Bursa, Kemaliye-Erzincan, Ordu and Trabzon provinces. Ethanol extracts of propolis (EEP) were prepared for chemical analysis. Gas chromatography coupled with mass spectrometry (GC-MS) was used for the chemical analysis in the organic compound base. Escherichia coli, Salmonella typhi, Proteus sp., Staphylococcus aureus, Bacillus subtilis and Beta Hemolytic Streptococcus bacteria were used to determine the antibacterial activity of propolis samples. All propolis samples have different chemical composition, however antibacterial activities of the propolis samples showed similar antibacterial properties. It was observed that all propolis samples affected to the growth of the gram positive bacteria. The activity against gram negative bacteria was weak.
