| Popis: | The essential oil from leaves of Eucalyptus globulus obtained by hydrodistillation, as well as its major compound 1,8-cineole, identified by gas chromatography coupled with a mass selective detector, were evaluated for their effectiveness against the storage fungi Aspergillus flavus and Aspergillus parasiticus. The evaluation was performed by compound dissolution in yeast extract sucrose (YES) medium and exposure to headspace volatiles. Complete fungal growth inhibition of both species was achieved with the essential oil by contact and volatile assays. Volatile exposure showed total inhibition at the lower level tested of 500 μL. The 1,8-cineole tested alone showed partial inhibition only at the highest level of 1.3492 μL. Aflatoxin B1 production was reduced in headspace volatile assays and partial inhibition was observed at the 200 μL dose of the essential oil. |
