Enantioseparation of kavain on Chiralpak IA under normal-phase, polar organic and reversed-phase conditions

J Sep Sci. 2008 Jul;31(12):2206-10. doi: 10.1002/jssc.200800044.

Abstract

First baseline HPLC enantioseparation of kavain is described. Complete enantiodiscrimination was achieved on the immobilised-type Chiralpak IA chiral stationary phase (CSP) using pure methanol and simple methanol-water and ethanol-water mixtures as eluents. A water-dependent enantioselectivity was clearly demonstrated. Performance of the Chiralpak IA CSP in polar organic and RP conditions was compared with that of five coated polysaccharide-derived CSPs used in normal-phase mode.
