Abstract:

A high performance liquid chromatography (HPLC) method was developed to determine olaquindox marker, methyl- 3-quinoxaline-2-carboxylic acid (MQCA) residue in animal tissues. MQCA in muscle tissues were extracted by hydrochloric acid hydrolysis, purified by MAX SPE, and then quantitatively determined by HPLC. The recovery rate of spiked MQCA at the addition range of 4.0-200μg/kg was 82.1%-90.3% with the relative standard deviation (RSD) of less than 7%. The limit of detection (LOD) was 4.0μg/kg.

Key words: high performance liquid chromatography (HPLC), marker residue of olaquindox, methyl-3-quinoxaline-2-carboxylic acid (MQCA)
