The worldwide contamination <strong>of</strong> foods and feeds with mycotoxins poses a<br />
significant health problem. Mycotoxins can cause acute or chronic intoxication<br />
and damage to humans and animals after ingestion <strong>of</strong> contaminated food and<br />
feed.<br />
Considering these as a first step the objective <strong>of</strong> our work is to evaluate the<br />
antifungal activity <strong>of</strong> some extracts from Punica granatum peels on some fungal<br />
strains producing mycotoxins. Pomegranate is an ancient fruit and a known rich<br />
source <strong>of</strong> bioactive compounds. It is only recently that modern scientists have<br />
systematically evaluated the fruit for its various medicinally useful properties. In<br />
the present work four extracts obtained by an ethanol, methanol extraction and<br />
maceration from Punica granatum peels were tested for their antifungal potential<br />
against three species <strong>of</strong> Aspergillus such as A. flavus, A. niger, A. ochraceus, and<br />
one species <strong>of</strong> Penicillium such as P. expansum.<br />
The assessment <strong>of</strong> antifungal activity is assayed by radial growth technique on<br />
solid medium content selected volumes <strong>of</strong> peel Punicagranatum extracts. The<br />
assessment <strong>of</strong> mycotoxinogenesis is released on Y.E.S medium mix with selected<br />
volumes <strong>of</strong> peel Punicagranatum extracts. The results <strong>of</strong> our work indicate that all<br />
the four extracts prevent totally the mycilial growth in solid and liquid medium with<br />
a percentage <strong>of</strong> 100% <strong>of</strong> all the fungal strains in selected concentration. Moreover<br />
the methanol extract was the more effective one and the fungal strain A.<br />
ochraceus was the most sensible one for all the extracts.<br />
In conclusion the results indicate that all the extracts which have been obtained<br />
from Punica granatum peels got an antifungal activity against the four fungal<br />
strains.<br />
