The aflatoxins are toxic and carcinogenic metabolites produced by fungi. Aflatoxin B1, the predominant compound produced by Aspergillus flavus and Aspergillus parasiticus, is the most toxic and carcinogenic of all mycotoxins. B1, B2, G1 and G2 have been analysed after isolation from corn by extraction with different solvents. The extracts were purified by OPLC rather than by liquid-liquid extraction and solid-phase extraction. After preconcentration of the extracts the aflatoxins were separated by use of 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.
