Abstract A high-performance liquid chromatography (LC) method was developed for the determination of halofuginone (HFG) in sturgeon muscle. The extracted samples were cleaned up by an immunoaffinity chromatography column that was prepared by covalently coupling polyclonal antibodies against HFG to cyanogen bromide (CNBr) activated Sepharose 4B. The eluate was evaporated to dryness, and residues were determined by LC with absorbance detection at 243 nm. Recoveries of HFG from samples fortified at 20-200 microg/kg levels ranged 74.6-81.1\%, with coefficients of variation of 0.7-8.6\%. The detection limit was estimated to be 10 microg/kg in a 2 g sample.
