A fast and easy method to determine residues of flubendiamide in different vegetable matrices was developed. The method involves extraction of sample with acetonitrile; dispersive solid phase clean up with PSA and anhydrous MgSO4; evaporation of the solvent followed by reconstitution with acetonitrile for LC analysis. The cleaned up residues were estimated by HPLC equipped with a UV detector at a wavelength of 210 nm. The analytes were separated on a reversed-phase C18 LC column. The limit of quantitation (LOQ) of flubendiamde in matrix was 0.1 mg kg−1 for cabbage, cauliflower and brinjal, 0.5 mg kg−1 for chilli. The recoveries of flubendiamide at the 0.1, 0.5 and 1.0 mg kg−1 fortification level were in the range of 90.21–97.92% with RSD values 1.05–5.26% in cabbage, cauliflower, brinjal and chilli.
