Abstract

A method has been developed for the determination of abamectin in tomatoes. Sample homogenization and extraction are performed simultaneously with acetonitrile/water/hexane. Abamectin and its isomer are selectively concentrated and derivatized by an instantaneous reaction with trifluoroacetic anhydride (TFAA)/1-methylimidazole. Quantification is achieved by HPLC with fluorescence detection
