title: [Studies on deoxynivalenol contamination in grain and its products in Anhui Province].
abstract: Contamination of deoxynivalenol (DON) in wheat, corn, barley, and wheat flour produced in Anhui Province were examined with thin-layer chromatography in 1983-1991. In total, 672 specimens were determined, and 63.2% of them were contaminated by DON, with an average contents of 908.7 micrograms/kg (a range of 0-13330 micrograms/kg). The contamination of DON in wheat and wheat flour was more severe than that in corn (P < 0.01). There was highly significant difference in the contamination of DON in wheat produced in different areas and years, with a P-value less than 0.01 by ANOVA, but no significant difference in corn (P > 0.1). It suggested the contamination of DON correlated with the incidence of scabby wheat in that area during these years.
