A composite material (MIP@Fe 3 O 4 @GO) based on molecular imprinted polymer (MIP), superparamagnetic Fe 3 O 4 particles and graphene oxide (GO) was prepared by the chemical coprecipitation method, and used to simultaneously separate and enrich two alkaloids (evodiamine and rutaecarpine) in the extract of Evodiae fructus . The as‐prepared MIP@Fe 3 O 4 @GO was characterized by Fourier transform infrared spectroscopy (FT‐IR), transmission electron microscopy (TEM), and vibrating sample magnetometer (VSM). The adsorption kinetics, isotherms, competitive adsorption, and reusability of MIP@Fe 3 O 4 @GO were also investigated. The results revealed that MIP@Fe 3 O 4 @GO was sensitive to the magnetic field and could be easily separated using an external magnet; MIP@Fe 3 O 4 @GO showed good recognition selectivity, as well as simultaneous enrichment and separation abilities for evodiamine and rutaecarpine in the extract of E. fructus with satisfactory recoveries. © 2016 Wiley Periodicals, Inc.
