In this paper essential oil of V. officinalis as potential antifungal agent was analyzed. Following micromycetes as test organisms were included: Penicillium ochrochloron, Alternaria alternata, Aureobasidium pullulans, Trichoderma viride, Cladosporium cladosporioides, Fulvia fulvium, Phomopsis helianthi and dermatomicetes Trichophyton rubrum, Trichophyton tonsurans, Epidermophyton floccosum i Microsporum canis. Throughout the macrodilution method on agar substrates, after incubation period, minimum inhibition concentration (MIC) was recorded. The concentration of 20 ml/ml showed fungistatic activity against T. viride. For species P. ochrochloron, A. alternata, A. pullulans MIC was 10 ml/ml, and for C. cladosporioides, F. fulvium and P. helianthi like for analyzed dermatomycetes MIC was 5 ml/ml. Further investigations will comprise larger number of testing fungi and examination of antifungal activities of single essential oil components of V. officinalis.
