Analysis of Fenpyroximate Residues in Eggplant, Aubergine (Solanum melongena L.) During Crop Production Cycle by HPLC and Determination of Its Biological Activity

Abstract

A method for determination of Fenpyroximate (Ortus) (5%) residues in eggplant (Solanum melongena L.) by HPLC is described. The analysis was done using HPLC equipped with a UV-Vis detector at 254 nm.  The degradation rate of Fenpyroximate was studied and the results indicated that final residue in eggplant reached 20.1% after 21 days which was considered safe for human and animal consumption, despite its insecticide effectively on eggplant pests.
