Effect of Ethanolic Extract of Jatropha curcas L.(Euphorbiaceous)in some Genera of Fungi Isolated from Contaminate Food


This study included the preparation of alcoholic (ethanol) by fermentation method of aerial part of Jatropha curcas L. .The detection on chemical compounds of secondary metabolism products of plant in crude extract revealed that are: alkaloids ,tannins ,glycosides ,saponins, phenolic compounds and steroids .The inhibitory effect of ethanolic extract against the fungi genera Aspergillus ,Penicillium ,Rhizopus and Fusarium, isolated from contaminated food is also determined by the percentage of inhibitory in petri dish at the concentrations (25, 50, 75,100,200 ) mg/ml ,the extract gave the inhibitory activity against fungi, so the percentage increased with the increasing of concentration specially at the high concentration 200 mg/ml against fungal isolates Aspergillus , Penicillium , Rhizopus and Fusarium :( 81 , 80 , 75.3 , 75.1)% respectively.
