title: Determination of moniliformin using SAX column clean-up and HPLC/DAD-detection.
abstract: This work describes a method for the determination of theFusarium mycotoxin moniliformin (MON) in cereals. In addition to the optimization of the clean-up and the HPLC determination the most efficient extraction mode was investigated on natural contaminated samples. The method was validated for maize and wheat using a calibration range from 57 to 2300 µg/kg. Due to the ionic nature of the toxin the clean-up of the extracts was carried out with strong-anion-exchange columns. Moniliformin was separated by reversed phase ion-pair-chromatography (RP-Ion pair-HPLC) and detected by DAD. The validated method yielded recoveries of 76%±9% (maize) and 87%±5% (wheat) and detection limits of 39 µg/kg and 30 µg/kg, respectively. The suitability of the developed method was demonstrated on natural contaminated samples.
