pharmacological effects due to molecule's chirality, one of the enantiomers is more potent,
and the other exhibits different activities of therapeutic interest. The preparative separation of
the verapamil enantiomers was performed using a continuous Varicol unit operated on a
scale of 1 g/day. Amylose tris (3, 5-dimethylphenylcarbamate) functioned as the stationary
phase, and n-hexane/isopropanol/ethanol mixtures were used as the mobile phase …
