Antimicrobial activity evaluation of the oleoresin oil of Pistacia vera L.
Keywords:
Essential oils, oleoresin of Pistacia vera L, strains tested, antimicrobial activity determinationAbstract
The hydrodistilled essential oils from the exudates of Pistacia vera L. stems have been tested against
three bacteria, Escherichia coli, Staphylococcus aureus and Proteus using three methods: agar disc
diffusion method, determination of MIC (minimal inhibitory concentration) and in the liquid phase, by
Maruzella method. The results obtained showed that E. coli was the greatest inhibitor of all the strains
tested, and that Gram negative bacteria (E. coli and Proteus spp.) showed more inhibition than that
observed on Gram positive bacteria (S. aureus) by the essential oil tested
