Abstract: In order to selectively extract trans-resveratrol from Chinese herbs, molecularly imprinted polymers (MIPs) were prepared with trans-resveratrol as the template molecule. The influences of porogenic solvents and functional monomers on the recognition properties of the polymer were studied. The MIP, which was prepared in acetone using 4-vinylpyridine as functional monomer, displayed good affinity and recognition property for the template molecule. This indicates that the 4-vinylpyridine can form hydrogen-bonding or ionic interaction with trans-resveratrol. Experimental result also indicated that the MIP column can separate trans-resveratrol from matrix components in the Polygonum cuspidatum extract
