环糊精是由Ｄ（＋）－葡萄糖单元通过α－１，４糖苷键连接的环状齐聚糖。其最典型的性质是能与许多客体分子形成包容配合物。高效液相色谱环糊精键合固定相广泛用于对映异构体，非对映异构体，结构异构体和常规化合物的分离。 Cyclodextrins are cyclic oligosaccharides linked by α-1,4 glycosidic bonds from D (+) - glucose units. Its most typical property is that it can form inclusion complexes with many guest molecules. High performance liquid chromatography cyclodextrin bonded phases are widely used for the separation of enantiomers, diastereomers, structural isomers and conventional compounds.
