Abstract
Aflatoxins difuranocoumarin derivatives are produced by fungi Aspergillus flavus, Aspergil‐ lus parasiticus and Aspergillus nomius [1] and they are part of the group of mycotoxins. From the twenty metabolites that have been formed endogenously in animals, aflatoxins B1, B2, G1 and G2 (AFB1, AFB2, AFG1 and AFG2) are the most common and the most toxic. The names of aflatoxins B1, B2, G1, and G2 are based on their florescence characteristics. Aflatoxin B1 and B2 show strong blue fluorescence under UV light, whereas aflatoxins G1 and G2 exhibit greenish yellow fluorescence [2]. All the aflatoxins have been classified as carcinogenic com‐ pounds for humans, but AFB1 has been tagged as the most dangerous, highly toxic, immu‐ nosuppressive, mutagenic, and teratogenic compound and its effects have been identified as well. Also, malabsorption syndrome and reduction in bone strength may occur due to AFs consumption. Aflatoxins not only have adverse effects on human health but also cause seri‐ ous economic losses when tons of foods have to be dropped or destroyed for being contami‐ nated with AFs.
