Summary:
Separation of enantiomers by means of high-performance liquid chromatography (HPLC), supercritical
fluid chromatography (SFC),and capillary electrochromatography (CEC) is of great importance
in pharmaceutical analyses. In recent years, separation of various types of racemates employs most
frequently chiral stationary phases based on macrocyclic antibiotics. This class of chiral selectors
includes vancomycin, teikoplanin, ristocetin A, teikoplanin without saccharide components, avoparcin,
etc.The reviewpaper describes the properties of selected antibiotics, the effect of chromato-graphic
conditions on enantioselectivity (effect of the composition of the mobile phase, effect of pH of the
mobile phase, effect of temperature), and the study of possible mechanisms of interaction, which
play an important role in the separation of enantiomers. Examples of the use of macrocyclic
antibiotics in the separation of various compounds by means of the HPLC, SFC, and CEC methods
follow.
Key words:
