A novel molecularly imprinted polymer(DMIP) for trans-resveratrol was fabricated with bonded β-cyclodextrin(β-CD) and methacrylic acid as double monomers. Molecularly imprinted solid phase extraction column prepared with bonded double monomers has higher imprinting effect to the template molecule. DMIP prepared using bonded β-CD and methacylic acid, either separately or combined have shown various recognition properties. The results of adsorption experiments indicated that the selectivity of DMIP is superior to those obtained with only methacrylic acid(SMIP). Molecularly imprinted solid phase extraction column was used to determine the trans-resveratrol in wine and Chinese liquor samples. The recoveries of 87.9%~93.2%, 87.9%~93.2% and 89.3%~91.2% are obtained for red wine and white wine and Chinese Liquor, respectively. This method is highly sensitive and specific for the analyte, along with a low limit of determination at 0.001 mg/L and a linear range from 0.003 to 2 mg/L.
