Fumonisins B1 And B2

The efficiencies of different clean-up procedures for crude corn extract from corn samples naturally contaminated by fumonisins B1 and B2 were compared. These procedures precede liquid chromatography determination with fluorescence detection. The efficiencies of immunoaffinity columns (IMA) strong anion exchange columns (SAX), as well as columns with reversed-phase C18 (RP C18) were investigated. No significant differences in the obtained results were found, regardless of the crude extract clea-nup procedure. However, the use of IMA columns for clean-up provided better chromatographic resolution, with the clean-up procedure being the simplest and the fastest. Also, because of the possibility of IMA column regeneration, it is possible to prepare ten samples on one column, so all in all, the lower price of SAX and RP C18 columns is of no great significance.
