Description
Summary:[Display omitted] •Pesticides were determined in royal jelly and propolis products by GC-MS.•The sample treatment procedure consists of a solvent extraction and a clean-up.•Matrix effect was not significant for all studied matrices and compounds.•LOQs were lower than MRLs established by the EU and reported values.•α-endosulfan and chlorfenvinphos residues were found in royal jelly products. We propose a new analytical methodology to determine seven pesticides (atrazine, chlorpyrifos, chlorfenvinphos, α-endosulfan, bromopropylate, coumaphos, and τ-fluvalinate) in royal jelly and propolis products using gas chromatography-mass spectrometry. Sample treatment, with minor modifications for propolis, consisted of a solvent extraction with a hexane and isopropanol mixture, and a further clean-up step. Meanwhile, chromatographic analysis (
