Abstract

The recent discovery that Aspergillus niger can produce fumonisins raises a new mycotoxigenic risk that requires additional studies to assess the impact on agricultural commodities. Here, we report the development and validation of a sensitive LC fluorescence method for the identification of fumonisin B2 in black aspergilli cultures. The performances of naphthalene-2,3-dicarboxaldehyde (NDA), o phthaldialdehyde (OPA) and 9 fluorenylmethyl chloroformate (FMOC) for the pre-column derivatization of samples were evaluated and compared. The best methodology included the following elements: NDA was ...
