Accurate quantification of pesticide residues is critical to ensure the quality and safety of Rhizoma Polygonati, a well-recognized medicine-food homologous herb widely applied in functional food development. Strong matrix interference in gas chromatography-tandem mass spectrometry (GC-MS) detection and notable quantitative bias are frequently induced by the abundant pigments, polysaccharides, saponins and endogenous components in the herbal matrix. Conventional PSA and C18 adsorbents in standard QuEChERS protocols …
