We examined analytical method for rapidly determining deoxynivalenol (DON) and nivalenol (NIV) in cereals. Since we used a solvent of high polarity, water, a column of mixed alumina-charcoal-celite, and a column of amberlite for extraction and clean up, we were able to remove partition and dehydration processes. We determined mycotoxin by ECD-gas chromatography after trimethyl-silylation. We made the limits of detemination of DON and NIV at 12 ng/g. When DON and NIV were added to wheat and barley at 120 ng/g level, the recoveries were 101 and 95%, 93 and 92%, and the coefficients of variation were 2.9 and 3.4%, 3.7 and 2.4%, respectively. This method should also be applicable to the analysis of food and feed.
