Preparation and Characterization of Trans-Resveratrol Imprinted Polymers

摘要

In order to selectively extract trans-resveratrol from Chinese herbs,molecu- larly imprinted polymers (MIPs) were prepared with trans-resveratrol as the template molecule.The influences of porogenic solvents and functional monomers on the recog- nition 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 cont- ponents in the Polygonum cuspidatum extract.
