V. Hormazabal et M. Yndestad, HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHIC DETERMINATION OF PRAZIQUANTELIN PLASMA AND TISSUES OF CULTURED FISH FOR RESIDUE AND PHARMACOKINETIC STUDIES, Journal of liquid chromatography, 18(3), 1995, pp. 589-597
A simple method for the determination of praziquantel in fish plasma a
nd tissues by HPLC is presented. The samples were extracted with aceto
ne, the organic layer then being separated with diethylether-hexane an
d evaporated to dryness. The lower limit of quantification was 5, 15,
and 20 mu g/kg, for muscle, liver, and plasma, respectively.
