Abstract
Abstract A high performance liquid chromatographic method (HPLC) for the determination of olaquindox, morantel, furazolidone, nitrofurazone and carbadox residues in swine muscles was developed. The drugs were extracted from muscles with acetonitrile and cleaned up by alumina column. HPLC analysis was carried out on an Inertsil C8 column with a mobile phase of acetonitrile-water-acetic acid (3:97:1), and the drugs were detected at 340 nm. The average recoveries of all drugs added to muscles at 0.1 ppm level were more than 75% and the detection limit of each drug was 0.03 ppm in muscles.
