A rapid method for analysis of deoxynivalenol (DON) was developed using high pressure liquid chromatography with reductive electrochemical detection (LCECD). Deoxynivalenol produced by Fusarium roseum growing on solid cornmeal and rice substrates and from naturally contaminated wheat was extracted and quantitated. Two deoxynivalenol producing isolates of Fusarium roseum (ATCC number28114, NCPRL-A) were incubated in stationary liquid culture in the presence of (1-/sup 14/C) sodium acetate to biosynthetically produce a radiolabeled toxin suitable for use in tissue distribution studies. Specific activities of 139 uCi/mmole (NCPRL-A on corn media), 67.5 uCi/mmole (NCPRL-A on rice media) and 21.5 uCi/mmol (ATCC number28114 on rice media) were obtained in this study and represent the first reported incorporation of /sup 14/C into deoxynivalenol. A minicolumn method for DON determination was also investigated.
