【 摘 要 】

Antifungal and antiaflatoxigenic activities of five methanolic plant extracts were evaluated against the toxigenicAspergillus flavusisolate. Extract ofPunica granatumshowed the highest antifungal and antiaflatoxigenic activities followed byZingiber officinalis.P. granatumextract absolutely arrested aflatoxin B1production at 5 mg/ml and inhibited 100% the mycelial growth ofA. flavusat 10 mg/ml.Zingiber officinalisandOlea europaeaextracts showed a moderate antifungal activities and exhibited a significant antiaflatoxigenic efficiency as they completely inhibited aflatoxin B1production at 15 mg/ml.Lantana camaraextract showed a weak antifungal activities while no effect was detected withAllium sativumL.The analysis of plant extracts by GC/MS showed thatP. granatumextract was mainly composed by ellagic acid (37.01%), pedunculagin (6.40%), punicalugin (5.64%) and polyphenol as lumicolchicine (4.68%) while components ofZ. officinaliswere gingerol (46.85%), cedrene (8.39%), zingiberene (7.40%) and α-curcumene (7.32%) respectively. The findings obtained from this study may contribute to development of potentially effective and environmentally safer alternative fungicides to protect the spoilage of wheat grains from the toxigenicA. flavus.
