Enantiomeric separations of 5 chiral drugs with 2 chial resolving agent, hydroxypropyl-β-cyclodextrin(HP-β-CD), highly sulfated-βcyclodextrin(HS-β-CD) and mixture of them, as chiral additives by capillary zone electrophoresis(CZE) were investigated, arid the good enantiomeric separations of 5 drugs were obtained successfully. Chiral recognition of HS-β-CD was compared with HP-β-CD. Synergistic effect of dual cyclodextrins systems in chiral capillary electrophoresis was investigated.
