A procedure was developed to determine nosiheptide residues in marketed meat and egg. Acetonitrile was used for the extraction, and the extract was partitioned with hexane to remove fat. The lower layer was reconstructed and quantitated by liquid chromatography using fluorescence detection at 357 nm excitation and 500 nm emission. The mobile phase consisted of 0.025% phosphoric acid-acetonitril...
