V. Hormazabal et M. Yndestad, DETERMINATION OF PRAZIQUANTEL IN MEDICATED FISH FEED AND SEDIMENT BY HPLC, Journal of liquid chromatography, 18(6), 1995, pp. 1231-1238
A simple method for the determination of praziquantel clohexylcarbonyl
-4-oxo-1,2,3,6,7,11b-hexahydro-4H- pyrazino [2,1-a]isoquinoline-4-one)
in medicated fish feed, and sediment by HPLC, is presented. The calib
ration curves were linear in the investigated areas, 0.5 - 5 mg/g praz
iquantel for fish feed and 30 - 500 ng/g for sediment, and the recover
y rates were 99 to 100%, respectively.
