AFB1, B2, G1 and G2 were analysed after isolation from corn by extraction with different solvents. The extracts were purified by overpressured-layer chromatography (OPLC) rather than by liquid-liquid extraction and solid-phase extraction. After preconcentration of the extracts the aflatoxins were separated using the Personal OPLC System and quantitative measurements were performed by fluorodensitometry. The OPLC technique combines the advantages of the HPLC and HPTLC and enables high sample throughput and low operating costs.
