Antifungal effect of Asphodelus tenuifolius extracts on mycotoxigenic fungi isolated from the imported France soft wheat marketed in the North and southern Ouest of Algeria

Abstract

Within the framework of our research of medicinal plants a phytochemical and biological study of Asphodelus tenuifolius has been conducted. The study consisted of evaluating the antifungal activities of most of the chemical constituents extracted from leaves by many solvents and tested on Aspergil-lus flavus, A. parasiticus, A. ochraceus, A. fumigatus, A. niger, Penicillium expansum, Fusarium oxysporum and Alternaria sp.The inhibitory activity of phytochemicals was evaluated on fungi isolating from the imported France soft wheat marketed in Algeria, according to two methods: in agar medium and in Y.E.S. medium. The antifungal activity of the four extracts was evalu-ated against eight mycotoxicogenic fungi, by using agar dilution method. The phytochemical analysis conducted on A. tenuifolius leaves and roots re-vealed the presence of many compounds and the antifungal test results indi-cated a great potential of antifungal activity. Aspergillus species proved the most sensitive but F. oxysporum was the most resistance fungus. These re-sults explain that we can use A. tenuifolius as a natural antifungal agent to inhibit and to control mycotoxicogenic fungi.
