Abstract: To separate and enrich morin, a molecularly imprinted polymer (MIP) was synthesized on chitosan by surface molecular imprinting technique and characterized with Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The results showed that MIP possessed better selectivity and recognition for morin in a mixture than that of non-imprinted polymer (NIP). The saturated adsorption amount of MIP was 8.0 mg/g, which was 4-fold than that of NIP, and the recovery in the elution step was 94.87% and 10.97% for MIP and NIP, respectively. These findings indicate MIP could realize the separation and pre-concentration of morin in real sample and may be used for solid phase extraction (MIP-SPE) protocol.
