Determination of the acid dissociation constants for some mycotoxins of the Alternaria alternata genus
Article Abstract:
Acid dissociation constants for three of the Alternaria alternata genus mycotoxins have been estimated. Species of this genus often infect grains before harvest if moisture is great, and if drying in the field does not occur there may be secondary metabolites. Havested fruits/vegetables high in moisture may be infected. Using conventional ultraviolet-visible (UV-VIS) spectroscopic studies at different pH values, alternariol monomethyl ether (AME), altertoxin-I (ATX-I), and alternariol (AOH) were studied. Acidic constants for first dissociations of the mycotoxins and the value for the acidic constant of phenol has been made, assuming acidity arises from phenolic groups.
