Methods:The enantiomers were separated by HPCE on a capillary(50 cm×50 μm,ID) with the running buffer solution of 20 mmol/L of sodium dihydrogen phosphate,which contained 1% sulfated-β-cyclodextrin and was adjusted to pH 3.

The effect was increased linearly with increasing the concentration of sulfonated β-cyclodextrin.

Three new kinds of the sodium salt of sulfonated β-cyclodextrins with different degrees of substitution were synthesized and characterized.

High performance capillary electrophoresis separation of chiral drug intermediates with sulfated-β-cyclodextrin as chiral selector;

With the method of capillary zone electrophoresis,the paper respectively tests sepration of highly sulfated-β-cyclodextrin(HS-β-CD) on three kinds of chiral amine drugs,under the conditions of phosphate buffer(50 mmol/L,pH2.

Study on the Supramolecular System of Two Water-Soluble Porphyrins with SBE-β-CD by UV Spectroscopy and Fluorescence;

The effects of pH of background electrolyte, the concentration of sulfobutyl ether-β-cyclodextrin on chiral separation were investigated.

RESULTS Using 10 mmol·L-1 sulfobutyl ether-β-cyclodextrin as the chiral selector,and 0.

The results showed that ketoconazole enantiomers were well separated by only adding sulfobutyl ether-β-cyclodextrin(SBE-β-CD) into the mobile phase.
