Abstract: The aim of this study was to prepare a method for quick resolution of gossypol. The chiral magnetic surface molecular imprinting polymers (chiral MMIP) were utilized. A chiral reagent (N-octyl-D-glucosamine) acted as a monomer, and magnetic nanoparticles were used as carriers to obtain chiral MMIPs. The chiral MMIPs could combine with (+)-gossypol molecules, and enable the separation of (-)-gossypol from racemic gossypol.The characterization of chiral MMIPs were detected by Infrared spectroscopic analysis and transmission electron microscopic (TEM). The results showed that the presence of monomeric methacrylate in the chiral MMIPs and the particle size of chiral MMIP was about 150 nm. The binding capacity of gossypol chiral MMIP indicated that the chiral MMIPs prepared in the laboratory were capable of binding well to gossypol. The polymer was then used as the stationary phase for column chromatography, and (-)-gossypol solution was thus isolated through chromatography. The product was tested by ultraviolet spectrum and optical rotation tests and was confirmed to be (-)-gossypol. Thus, we established a simple, rapid, and cost-effective method for separating chiral compounds.
