Abstract: The modified silica gel core with ending double bond was synthesized by the reaction of the Si-OH on the silica gel surface with 3- glycidoxypropyltrimethoxysilane, then the core-shell structural amino acids molecularly imprinted separation medium was prepared through coating the molecularly imprinted polymers on the surface of modified silica gel with N-Boc-L-Trp as the template molecule by molecular imprinting technology. The as-prepared imprinted polymers had good adsorbability for N-Boc-L-Trp, the amount of saturated adsorption and imprinting efficiency were 85. 96 mg/g and 70. 67% respectively, which was obviously higher than that of the product obtained from the classical bulk polycondensation. The template molecule with enantiomers was fast baseline separated by loading the as-prepared molecularly imprinted separation medium into high performance liquid chromatographic column with separating degree 1. 64
