Monitoring pesticide residues in wine is essential for ensuring food safety, as these compounds and their metabolites can persist in the final product and pose potential health risks. This study reports the development of a hybrid sorbent based on graphene oxide anchored to aminosilica particles (GO@Si), functionalized with ionic liquids (ILs) via direct anion-exchange. Among the tested combinations, GO@Si-[VHIm]+PF6- exhibited the best extraction performance due to its multiple interaction mechanisms with analytes. This sorbent was integrated into a microextraction by packed sorbent (MEPS) system for the extraction of six multiclass pesticides from wine, followed by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) analysis. After optimizing extraction conditions using univariate and multivariate approaches, the method demonstrated excellent linearity (r(2) >= 0.9958), satisfactory precision (RSDs < 15 %), and recoveries ranging from 49 % to 112 %. Limits of quantification were from 0.030 to 0.130 ng mL(-)(1), with negligible matrix effects in white, red, and ros & eacute; wines. The method also presented notable green advantages, including device reusability (up to six cycles) and low solvent consumption (0.7 mL per extraction). Sustainability assessments using AGREEprep and BAGI yielded favourable scores (0.52 and 57.5, respectively). This pilot study provides a promising and environmentally conscious analytical approach for multiclass pesticide monitoring in wines, with potential for further development into routine analysis.
