Enantioseparation of ß-carboline, tetrahydroisoquinoline and benzazepine analogues of pharmaceutical importance: Utilization of chiral stationary phases based on polysaccharides and sulfonic acid modified Cinchonaalkaloids in high-performance liquid and subcritical fluid chromatography.

•Polysaccharide- and Cinchona alkaloid-based chiral stationary phases are studied.•ß-carboline, tetrahydroisoquinoline, and benzazepine analogues were enantioseparated.•Stereoselective retention and separation characteristics in HPLC and SFC are discussed.•Effects of structural peculiarities of the studied analytes are revealed.
