The separation of enantiomers of 16 basic drugs was studied using polysaccharide‐based chiral selectors and acetonitrile as mobile phase with emphasis on the role of basic and acidic additives on the separation and elution order of enantiomers. Out of the studied chiral selectors, amylose phenylcarbamate‐based ones more often showed a chiral recognition ability compared to cellulose phenylcarbamate
使用基于多糖的手性选择剂和乙腈作为流动相,研究了16种基本药物的对映异构体的分离,重点研究了碱性和酸性添加剂对对映异构体的分离和洗脱顺序的作用。在研究的手性选择剂中,与纤维素苯基氨基甲酸酯衍生物相比,基于直链苯基氨基甲酸酯的选择剂更经常显示出手性识别能力。观察到甲酸作为添加剂对某些基本药物的对映体拆分和对映体洗脱顺序的有趣影响。因此,例如,几种β-阻滞剂(阿替洛尔,索他洛尔,甲苯酚)的对映异构体分离不仅可以通过在流动相中添加更常规的碱性添加剂来实现,而且可以通过添加酸性添加剂来实现。而且,手性27:228–234,2015年。©2015 Wiley Periodicals,Inc.
