Abstract: Fe3O4@hybrid-molecular-imprinted polymers (Fe3O4@HMIPs) with three monosaccharide templates (D-(+)-galactose, L-(-)-fucose, and D-(+)-mannose), and hybrid materials were modified by deep eutectic solvents (DESs). The materials obtained were combined with solid-phase extraction (SPE) to purify of D-(+)-galactose, L-(-)-fucose, and D-(+)-mannose from seaweed, and the SPE procedure was optimized further. Compared to Fe3O4@HMIPs, DESs-Fe3O4@HMIPs were developed to achieve stronger recognition and higher recoveries of D-(+)-galactose, L-(-)-fucose, and D-(+)-mannose from seaweed. The optimal practical recoveries of the three monosaccharides, D-(+)-galactose, L-(-)-fucose, and D-(+)-mannose, purified by DESs-4-Fe3O4@HMIPs from seaweed were 90.12, 92.82, and 91.94%, respectively. When acetone was used as the washing solution, the actual amounts extracted were 6.87, 4.17, and 5.29 mg g-1, respectively
