摘要：The aims of this study is to evaluate the level of fumonisin B1 and B2 in sorghum
(Sorghum bicolor) and millet (Pennisetum spp). To do this, a method for assaying FB1
+ FB2 has been validated and the quantification limits of FB1 and FB2 obtained are
respectively 17.5 μg / kg and 22.1 μg / kg. The extracts were purified on immunoaffinity
cartridges. The detection and quantification of fumonisins was carried out by HPLC
equipped with a fluorescence column detector RP 18. One hundred (100) samples of
sorghum and millet were collected in three (3) localities in Côte d'Ivoire namely
Korhogo, Boundiali and Abidjan. 45% of the samples taken were fumonisin
contaminated, of which 32% had FB1 levels with an average of 40.71 5.28 μg / kg,
compared to 13% for a presence in FB1 + FB2 at an average concentration of 206.71
17.96 μg / kg . These detected levels were all below the maximum tolerable level set at
4000 μg FB1 + FB2 / kg in raw cereals according to EC Regulation 1126/2007.
