Abstract: A rational design approach was taken to the planning and synthesis of a molecularly imprinted polymer(MIP)capable of extracting puerarin from pueraria extract.The polymer was evaluated by static adsorption experiment.A molecular modeling approach was used to elucidate template-monomer interaction.Data from spectral analysis were used to prove the prediction made by molecular modeling.The MIPs have high selectivity to puerarin,the recovery rate of puerarin at 78.0 %,and purity at 86.5 % were attained.The successful preparation of molecular-imprinted polymers for solid-phase extraction for puerarin provides an innovative opportunity for the separation of traditional Chinese medicine.
