text: Macrocyclic chiral stationary phases consist of a silica support, on which macrocyclic antibiotic molecules are bonded. The commonly used macrocyclic antibiotics include rifamycin, glycopeptides (for example, avoparcin, teicoplanin, ristocetin A, vancomycin, and their analogs), polypeptide antibiotic thiostrepton, and aminoglycosides (for example, fradiomycin, kanamycin, and streptomycin). The macrocyclic antibiotics interact with the analyte through hydrogen bonds, dipole-dipole interactions with the polar groups of the analyte, ionic interactions and π-π interactions.
