  • Title: High-performance liquid chromatographic enantioseparation of flavanones on 2-hydroxy- 3-methacryloyloxypropyl beta-cyclodextrin copolymer coated silica phase.
    Author: Carbonnier B, Janus L, Morcellet M.
    Journal: J Chromatogr Sci; 2005 Aug; 43(7):358-61. PubMed ID: 16176648.
    Abstract:
    Chromatographic resolution of four flavanones is achieved by reversed-phase high-performance liquid chromatography (HPLC) on a chiral stationary phase based on silica coated with a (2-hydroxy-3-methacryloyloxypropyl beta-cyclodextrin-co-N-vinylpyrrolidone) copolymer. The influence of the mobile phase water content and the nature of the organic modifier on the retention and resolution is evaluated. Monosubstituted flavanones are better resolved than the unsubstituted one. Nevertheless, the 6- and 7-methoxy substituents enhance retention and chiral recognition to polymeric beta-cyclodextrin stationary phase less than the 6-hydroxy group.
