✦ Synopsis

Abstract

Dansyl derivatives of racemic phenylalanine and its analogs have been resolved by microcolumn liquid chromatography with γ‐cyclodextrin as mobile phase additive. The enantioselectivity of the system was influenced by the concentrations of both γ‐cyclodextrin and acetonitrile in the mobile phase. Enantiomers of phenylalanine, phenylglycine, and tyrosine were resolved by isocratic elution in a single chromatographic run.
