Abstract
Disk diffusion method was used to determine the antimicrobial activity of Pistacia terebinthus gal. Our standard microorganisms (Staphylococcus aureus ATCC 29213, Pseudomonas aeruginosa ATCC 27853, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922) were taken into brain heart infusion broths and their concentrations were prepared according to Mc Farland 0.5 chart. They were inoculated on Mueller Hinton agar media using sterile swab sticks. Bacteria were incubated at 35.5-36.5 degrees for 24 hours. The inhibition zones formed around the discs after incubation were measured with the help of a ruler and evaluations were made. GC-MS analysis of gal extract of P. terebinthus plant was performed. Approximately 85 components have been identified in the GC spectrum, besides the components contained in the extract and decomposition products are also available. The GC chromatogram of the extract is given, as well as the names and probability ratios of the components determined on the fractions that can be analyzed. Gal extract of P. terebinthus plant has positive effect on gram (+) bacteria Staphylococcus aureus and Enterococcus faecalis and inhibited bacteria to a large extent. Considering the harms of antibiotics, it is thought that it would be more advantageous to use the extract in case of drug requirement, since the extract we extract is natural.
