Abstract: Different kinds of deep eutectic solvents based on choline chloride and ionic liquids based on 1-methylimidazole were used to modify hybrid molecularly imprinted polymers with the monomer γ-aminopropyltriethoxysilane-methacrylic and three templates (rutin, scoparone, and quercetin). The materials were adopted as solid-phase extraction packing agents, and were characterized by FTIR spectroscopy and field emission scanning electron microscopy. The hybrid molecularly imprinted polymers modified by deep eutectic solvents had high recoveries and a strong recognition of rutin, scoparone, and quercetin in Herba Artemisiae Scopariae than those modified by ionic liquids. In the procedure of solid-phase extraction, deep eutectic solvents-2-hybrid molecularly imprinted polymers were obtained with the best recoveries with rutin (92.27%), scoparone (87.51%), and quercetin (80.02%), and the actual extraction yields of rutin (5.6 mg/g), scoparone (2.3 mg/g), and quercetin (3.4 mg/g). Overall, the proposed approach with the high affinity of hybrid molecularly imprinted polymers might offer a novel method for the purification of complex samples
