Abstract

A procedure for high-performance liquid chromatographic (HPLC) determination of triflumizole and its metabolite (Met) in crops was examined. Triflumizole and Met in sample crops were extracted with methanol and re-extracted into methylene chloride. After clean-up of the extract on a Florisil column, triflumizole and Met were determined by HPLC with UV detection at 238 nm. The HPLC column was packed with Nucleosil 5 C18 (ODS, 5 micron) and the eluent was acetonitrile-3 mM carbonate buffer (7:3, v/v, pH 9.0). The detection limit was 0.01-0.02 ppm and the recoveries from spiked crops (0.5 ppm) were 73-99% for triflumizole and 74-94% for Met. Triflumizole and Met were determined simultaneously and the method was shown to be applicable to residue analysis of these compounds in crops sprayed with Trifmine in fields.
