Abstract: Berberine-Cl imprinted polymer was synthesized on silica-gel particle as a sacrificed material by using berberine-Cl as template, MAA or 4-VP, EDMA and AIBN as function monomer, cross-linker and initiator, respectively. Polymer particle size was observed by optical microscope and its rebinding behavior to template investigated by IR spectrum and static adsorption of berberine-Cl on polymers. Results indicated a higher rebinding ability of MIP prepared by using MAA as functional monomer than by using 4-VP. This selective rebinding of template on the MIP resulted from specific affinity sites complementary to template in size, shape and functional group. Also, dissociation constants and maximum adsorption amount of two types of adsorption sites on MIP were obtained by Scatchard analysis
