Özet

Essential oil isolated from Nepeta meyeri Benth, obtained by hydrodistillation, was analyzed in GS and MS. Totally, 11 components were identified in the essential oil, representing 99.99% of the isolated oil. Main essential oil components were found to be 4a alpha,7 alpha,7a beta-Nepetalactone (80.32%); 4a alpha,7 alpha,7a alpha-Nepetalactone (10.32%), trans-Pulegol (3.13%); 1,8 Cileole (2,95%). Antifungal activities of the oil were tested on the growth of 16 phytopathogenic fungi. Antifungal assays showed that N. meyeri oil completely inhibited mycelial growth of the 16 phytopathogenic fungi; their antifungal effects were higher than the commercial fungicide "benomyl". Essential oil of N. Meyeri, at different concentrations (0.25, 0.50 and 1.0 mg/ml), significantly prevented the development of all plant pathogenic fungi. Antifungal activities of the oil indicated that there was an inhibition in mycelial growth of all tested pathogenic fungi, ranged from 18.5 to 100% at oil treatment concentrations, ranged from 0.25 to 0.5% mg/ml. N meyeri essential oil blocked the 16 plant pathogenic fungi by 100% with 18.5% growth. The findings of the present study suggest that essential oils have a potential use as fungicides.
