Abstract: A HPLC method was developed for the determination of sodium nifyrstylenate in milk and dairy products. Samples were extracted with acetonitrile, followed by clean-up by liquid-liquid extraction with n-hexane. Chromatographic peak area was linearly correlated with sodium nifyrstylenate concentration within a range of 10.0 to 200.0 ng/mL, with a correlation coefficient of larger than 0.9996. The limit of detection of the method was 20.0μg/kg. This method is simple and quick, and is therefore suitable for the monitoring and determination of massive export and import samples.

Key words: sodium nifurstylenate, residues, high performance liguid chromatography, determination
