Abstract

Spinosad is an insect control agent that is derived from a naturally occurring organism and is effective on a wide variety of crops, including citruscrops. A method is described for the determination of spinosad and its metabolites in citrus crops and orange processed commodities. The method determines residues of the active ingredients (spinosyns A and D) and three minor metabolites (spinosyn B, spinosyn K, and N-demethylspinosyn D). For driedorange pulp and orange oil, the method has a limit of quantitation (LOQ) of 0.02 mu g/g and a limit of detection (LOD) of 0.006 mu g/g. For all othersample matrices (whole fruit, edible fruit, juice, and peel), the method has an LOQ of 0.01 mu g/g and an LOD of 0.003 mu g/g. The analytes are extracted from the various sample types using appropriate solvents, and the extracts are purified by liquid-liquid partitioning and/or solid-phase extraction. All five analytes are determined simultaneously in the purified extracts by reversed phase high-performance liquid chromatography with ultravioletdetection at 250 nm.
