Abstract: | A simple multi-residue method was developed for the simultaneous determination of abamectin, ivermectin, doramectin, and eprinomectin in rabbit feces. Samples were extracted with acetonitrile, cleaned up with a C18 solid-phase extraction cartridge, and analysed by LC with fluorescence detection after derivatization. Abamectin, ivermectin, doramectin, and eprinomectin were detected at levels of 2–500 ng g?1; the average recoveries ranged from 73.2 to 99.6% with relative standard deviations of 2.5–11.3%. The limits of detection were 0.1–0.4 ng g?1. |
