摘要: β-环糊精键合硅胶经对甲苯磺酰化后,与8-羟基喹啉反应得到8-羟基喹啉衍生化β-环糊精键合硅胶固定相(QCDS).采用元素分析、热分析及固体核磁波谱对键合固定相进行表征。考察了QCDS对位置异构体、丹磺酰化氨基酸异构体、苯丙酸类药物和核苷等的分离性能。

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.

Key words: HPLC, Bonded silica stationary phase, β-Cyclodextrin, 8-Quinolinol
