Preliminary Study on the Antifungal and Antimicrobial Activities of Some Medicinal Plants of Turkey

In this study, acetone, alchol and hexane extracts Aloysia triphylla, Mentha aquatica, Foeniculum vulgare, Calendula officinalis, Salvia officinalis and Rumex acetosa used for medicinal purpose in Turkey were tested for antimicrobial activity by the diffusion method. These extracts were tested on Staphylococcus aureus NRRL-B 767, Micrococcus luteus, Bacillus subtilis NRS-744, B.cereus ATCC 11778, Escherichia coli ATCC 25922, Listeria monocytoponus ATCC 7644, Klebsiella pneumoniae, Yersinia enterocolitica, Proteus vulgaris, Enterococcus fecolis ATCC 29212, Xanthomonas phaseoli, Pseudomonas fluorescens, Fusarium oxysporum, F. culmorum, F.aveneceum, F.moniliforme, Gaeumannomycetes graminis var. tritici, Alternaria citri and Trichoderma harzianum. As conclusion, extracts of Aloysia triphylla, Mentha aquatica, Foeniculum vulgare, Calendula officinalis, Salvia officinalis and Rumex acetosa inhibited the growth of microorganisms used in these tests at different ratios. We have found that acetone extracts of tested plants relealed antimicrobial activity against bacteria but it had no antifungal activity against fungi used in this study.
