ABSTRACT
Aflatoxin Bj [AFBj] is a highly toxic and hepatocarcinogenic metabolite produced by Aspergillus species. Some natural products are known to kill fungi and destroy toxins and toxin-producing agents. The purpose of this study is to provide experimental data on the antifungal activity of cumin oils and their components that could be considered suitable for application in foods and drugs. The essential oil [EO] of Cuminum cyminum L. collected from Alborz Mountain, Iran, was obtained by hydro-distillation. The oil was analyzed by gas chromatography [GC] and chromatography/mass spectrophotometry [GC/MS]. The antifungal activity of the oil was studied with regard to the inhibition of the growth of Aspergillus flavus PICC-AF39 .Aspergillusflavus PlCC-AF24,Aspergillusparasiticus NRRL-2999 and Aspergillus niger. The minimal inhibitory [MIC] and minimal fungicidal [MFC] concentrations of the oil were determined. a-Pinene [29.2%], limonene [21.7%], 1,8-cineole [18.1%], linalool [10.5%], linalyl acetate [4.8%], and a-terpineole [3.17%]were the major components of the essential oil from C. cyminum L, and the oil showed a strong inhibitory effect on fungal growth. Essential oils could be safely used as preservatives in pharmaceuticals as well as health and food products to protect them against toxigenic fungal infections
