ABSTRACT
A method for determination of triforine using high-performance liquid chromatography with electrospray tandem mass spectrometry was developed. A simple ethyl acetate extraction with solvent exchange into water/methanol was used for sample preparation. The method was validated at 0.01 and 0.05 mg kg(-1) levels in apple, tomato and tinned blackcurrants. Recoveries were in the range 56.6-99.8% and no matrix suppression or enhancement effects were observed.
