Abstract:
Pectins were investigated as chiral selective agents in capillary electrophoresis. Successful enantioresolution of antihistaminic and antimalarial compounds, as well as others, was achieved by utilizing potassium polypectate as the chiral selector. Changes in pH, chiral additive concentration and capillary type were studied in relation to chiral resolution. The effect of degree of esterification of pectin materials on chiral recognition was also evaluated.
