Determination of 10 Sulfonamide Residues in Meat Samples by Liquid Chromatography with Ultraviolet Detection Author(s): Marcello Di Sabatino , Anna Maria Di Pietra, Luigi Benfenati, Bruno Di Simone Journal of AOAC INTERNATIONAL Print ISSN: 1060-3271 Volume: 90 | Issue: 2 Cover date: March/April 2007 Page(s): 598-603 Abstract text A liquid chromatography (LC) method is described for the simultaneous determination of 10 commonly used sulfonamide drug residues in meat. The 10 sulfonamide drugs of interest were sulfadiazine, sulfathiazole, sulfamerazine, sulfadimidine, sulfamethizole, sulfamonomethoxine, sulfachloropyridazine, sulfadoxine, sulfadimethoxine, and sulfaquinoxaline. The residues were extracted with acetone–chloroform (1 + 1). Sulfonamides were quantitatively retained in the extracting solution and afterwards eluted from a cation-exchanger solid-phase extraction cartridge with a solution of methanol–aqueous ammonia. |
