Determination of deoxynivalenol in corn

Abstract

By applying previously established optimal conditions for determination of deoxynivalenol by liquid chromatography with DAD detector, its content was determined in this work in corn samples artificially inoculated with Fusarium graminearum. The samples presented material of different genetic origin, and are frequently used as parent components of corn hybrids in the moderate belt. The obtained values for deoxynivalenol content were not higher than the maximum permitted level (1 g/g), regardless of the fact that the fungus was artificially inoculated. This is probably a consequence of the absence of humid weather, as well as extremely high temperatures during the sampling period (year 2003).
