Abstract
Fifteen corn kernel and corn screening samples were analyzed for the p resence of fumonisin toxins. Samples were extracted with acetonitrile/ water (1:1) and cleaned up with C-18 solid phase extraction (SPE) cart ridges. Analysis of fumonisins was carried out by on-line capillary li quid chromatography-fast atom bombardment mass spectrometry (capillary LC/FAB/MS). Two isomers of partially hydrolyzed fumonisin B-1 (PHFB1) were detected in five samples, and N-acetyl fumonisin B-2 (FA(2)) was detected in one sample. Hydrolyzed fumonisin B-1 (HFB1) was also dete cted in one sample, but further confirmation is needed.
