Analytical methods for detection and estimation of aflatoxins* uri icon

abstract

  • The aflatoxins are a group of highly toxic metabolites produced by the fungi Aspergillus flavus and Aspergillus parasitucus. Four of these metabolites designated aflatoxins B1, B2, G1, and occur commonly in commodities infected with these fungi. The distinguishing letters refer to the colour of the fluorescence exhibited by the compunds on this layer chromatograns (TLC) when viewed in ultra violet light (UV), and the suffixes refer to their respective positions on such chromatograms. The term aflatoxin is used to refer to any member of a group of these chemical compounds of related structure. Aflatoxins are extremely poisonous to farm and domestic animals and to human and are known to have strong cancer roducing properties, of these four naturally occuring aflatoxins,aflatoxin B1 is the most potent hepatocarcinogen
