Foi padronizado e validado um método analítico para determinação de resíduos de abamectin, doramectin e ivermectin em fígado bovino empregando extração com acetonitrila, purificação com cartucho de C18 , derivatização, detecção e quantificação por CLAE/FL. Nos ensaios com amostras adicionadas de solução padrão em níveis entre 5 e 100mg/kg as recuperações médias obtidas variaram de 69,0 a 101,4% com valores de coeficiente de variação entre 5,5 e 28,1%. O limite de detecção e quantificação do método, para os três resíduos estudados, foi 5µg/kg.A method for determination of abamectin, doramectin and ivermectin residues in bovine liver was standardized and validated using acetonitrile extraction, clean-up with nd C18 cartridges, derivatization,...
