Detection of Two Naturally Occurring Structural Isomers of Partially Hydrolyzed Fumonisin B1 in Corn by On-Line Capillary Liquid Chromatography−Fast Atom Bombardment Mass Spectrometry

Fifteen corn kernel and corn screening samples were analyzed for the presence of fumonisin toxins. Samples were extracted with acetonitrile/water (1:1) and cleaned up with C18 solid phase extraction (SPE) cartridges. Analysis of fumonisins was carried out by on-line capillary liquid chromatography−f...

Description
Summary:Fifteen corn kernel and corn screening samples were analyzed for the presence of fumonisin toxins. Samples were extracted with acetonitrile/water (1:1) and cleaned up with C18 solid phase extraction (SPE) cartridges. Analysis of fumonisins was carried out by on-line capillary liquid chromatography−fast atom bombardment mass spectrometry (capillary LC/FAB/MS). Two isomers of partially hydrolyzed fumonisin B1 (PHFB1) were detected in five samples, and N-acetyl fumonisin B2 (FA2) was detected in one sample. Hydrolyzed fumonisin B1 (HFB1) was also detected in one sample, but further confirmation is needed. Keywords: Mycotoxin; fumonisin; capillary LC/FAB/MS
