Determination of alternariol in tomato paste using solid phase extraction and high – performance liquid chromatography with fluorescence detection.

A new method for the determination of Alternaria toxins in tomato paste, involving solid phase cartridges for extraction before HPLC fluorescence detection with a reversed phase column and isocratic elution, is described. The method is linear in the range 5.2 – 196 mg/kg of alternariol (AOH) in tomato paste. Good recoveries were obtained for AOH at all levels assayed (minimum 77.2%). The detection limit of the AOH toxin in samples of tomato paste was 1.93 mg.kg. The precision of the method was demonstrated with a good repeatability (RSD = 2.98%) and reproducibility (RSD = 9.35%).
