Abstract: A molecularly imprinted polymer (MIP) was prepared using quercetin as the template and acrylamide as the hydrogen-bonding functional monomer in a pol ar solvent. The polymer exhibited high affinity for quercetin and good selectivi ty among the tested compounds. And when it was used as an extraction cartridge f or the hydrolyzate of gingko leaves,it can purify the flavonoid component in the hydrolyzate,catching mainly quercetin and kaempferol. Thus it demonstrated th e feasibility of using MIP in extracting specific pharmacophoric compounds direc tly from herbs.

Key words: Molecularly imprinted polymer, Quercetin, Kaempferol, Gingko, Acr ylamide
