摘要

A liquid chromatographic-atmospheric pressure ionization ion spray method for the determination of some coccidiostatics in chicken egg, fat, liver, muscle, and plasma is presented. The samples were extracted with acetone-tetrahydrofuran. The water and the organic layer was then separated using a liquid-Iiquid extraction step and the organic phase was then evaporated to dry- ness. The dry residue was dill.lted in hexane and a portion of the organic phase was cleaned-up with ~ simple step for ethopabate analyses while the rest of the organic phase was purified using a silica solid phase extraction column to analyse lasalocid,mon- ensin, narasin, and salinomycin. The water phase (aniprolium analyses) was diluted with water, filtered, and injected into the LC-MS. Three different analytical columns were used. The detection limits were from 1 ng/g to 7 ng/g for chicken tissue and from 4 to 10 ng/mL for plasma.
