Using the polyvinylidene fluoride microporous membrane as the supporting membrane and zinc(II)-quercetin complex as template, the molecularly imprinted polymer membranes were synthesized through in situ polymerization by UV irradiation. The imprinted membranes exhibited selective permeation for quercetin in certain zinc(II) acetate solution through permeation binding experiment. The influences of cations and anions on the selective permeation of imprinted membranes were investigated. It will be helpful for the separation and enrichment of quercetin in herbal medicine.

Key words: molecularly imprinted membrane, membrane permeation, quercetin
