Abstract: 8-Quinolinol derivatized β-cyclodextrin bonded silica(QCDS) has been prepared for high-performance liquid chromatography. The resulting bonded silica was characterized by using elemental analysis, thermal analysis and solid state NMR. The separation performance of QCDS for positional isomers, dansylamino acids, phenylpropionic acids and nucleosides was investigated. It was found that the retention of p-nitroaniline and p-nitrophenol was much smaller on the QCDS than on β-cyclodextrin bonded silica(CDS), whereas the retention of their ortho-and meta-isomers was similar on the both bonded stationary phases.
