Three kinds of sulfated β‐cyclodextrin (S‐β‐CD), including a single isomer, heptakis‐6‐sulfato‐β‐cyclodextrin (HS‐β‐CD), degree of substitution (DS) of 7, which was synthesized in our laboratory and another two commercialized randomly substituted mixtures, a sulfated β‐cyclodextrin with DS of 7 to 11, as well as a highly sulfated‐β‐cyclodextrin with DS of 12 to 15, were used for the enantioresolution
三种硫酸化的β-环糊精(S-β-CD),包括一个异构体庚七-6-硫酸盐-β-环糊精(HS-β-CD),取代度(DS)为7,合成于我们实验室和另外两种商业化的随机替代混合物,DS值为7至11的硫酸化β-环糊精,以及DS为12至15的高度硫酸化β-环糊精用于对映12种药物的对映体(β毛细管电泳中的阻滞剂,苯乙胺和抗胆碱能药)。系统地研究和比较了不同浓度的S-β-CD和背景电解质pH下的对映体分离。根据实验结果,讨论了S-β-CD的性质和分析物结构对对映体分离的影响。
