Abstract: D-Glucose was used as a dummy template in a strategy to fabricate boronate-based hollow molecularly imprinted polymers (h-MIPs) for the recognition of glycosides. 3-Aminophenylboronic acid (APBA) was selected as the functional monomer to impart glycoside binding capability. A polystyrene core was synthesized via an emulsifier-free emulsion polymerization. It was then be corroded to form a hollow structure where the binding sites on the inner surface can be fully utilized. Adsorption studies indicate that the resulting h-MIPs can specifically recognize glycosides. The h-MIPs were applied as a sorbent for solid phase extraction of the glycosides (daidzin, glycitin, rutin, and genistin) in soy products. Following desorption with 1% TFA in acetonitrile-water (3:7, v/v), the glycosides were quantified by HPLC with UV detection. The detection limits for the glycosides range from 3.5 to 10.8 ng mL-1
