摘要：
Two cholic acid derivatives have been synthesized and bonded to porous silica via a hydride-modified substrate. The supports obtained, which were characterized by differential scanning calorimetric and infrared measurements, were found to be enantioselective for a variety of analytes in normal-phase high-performance liquid chromatography. Optimization of enantiomer separations was achieved by studying the influence of mobile phase composition. The effect of substituents on the retention and resolution of hydantoins and naphthylethyl-amines has been evaluated. General considerations of the separation mechanism on both stationary phases are discussed.
