Abstract
A liquid chromatographic method was developed for determination of nosiheptide in swine kidney and liver. The tissue samples were extracted with acetonitrile and defatted with hexane. The analytes were determined at a fluorescence excitation/emission wavelength of 357/515 nm and with gradient elution program. The limits of detection and limits of quantification were 5 and 20 ng g−1, respectively, for swine kidney and liver. The mean recoveries for nosiheptide in swine kidney and liver ranged from 70.3 to 97.4% with coefficients of variation below 11.3% at 20–100 ng g−1 fortification levels.
