Abstract: Rhein magnetic molecularly imprinted polymer (Fe3O4 @ SiO2 @ MIP) was prepared based on magnetic particles by using rhein as the template molecule, phenyl and amino silanes as binary functional monomers and tetraethyl orthosilicate (TEOS) as cross-linking agent. The Fe3O4 @ SiO2 @ MIP was characterized by SEM and IR. The results showed that rhein imprinted layer was grafted onto the magnetic particles surface successfully. The Fe3O4 @ SiO2 @ MIP has uniform cube structure and the thickness of imprinted shell is about 75-100 nm. Combined with magnetic solid phase extraction (M-SPE) and HPLC technology, the imprinted material employed as stationary phase was used to separate, enrich and detect rhein, emodin, chrysophanol and physcion from kiwi fruit root extractives successfully.
