effect some of plant extracts of growth the fungus Aspergillus flavus and Aspergillus parasiticus and production aflatoxin B1


Laboratory experiments were carried out in the postgraduate laboratories, Biology Department – College of Education for pure Sciences / Kerbala University . The Study aimed to investigate of the effect some of each alcoholic and water extracts of Hibiscus sabdariffa , Eucalyptus Camaldulensis and Mentha spicata on the fungus A. flavus and A.parasiticus and production aflatoxin B1. Results showed that, the extracts of Hibiscus sabdariffa, Eucalyptus Camaldulensis and Mentha spicata plants each alcoholic and water at 10, 20 and 30 mg /ml inhibited the growth of those two fungi extracts of Roselle and Eucalyptus plants inhibited the growth by 100% at 30mg/ml, the colony appeared while white small isolate. the alcoholic extract was superior as compared with the water extract.Results also revealed that , the treatment of those fungi with 20 and 30 mg/ml of alcoholic extract of Roselle plant , water extract of Roselle , Eucalypts and Mint plants as well as the treatment of fungi with 10% of water extract of Eucalyptus plant no aflatoxin B1 was detected
