## Evaluation of non-polar interactions in chiral recognition by alkylated b-and c-cyclodextrin chiral stationary phases The gas chromatographic separation of enantiomers of seven N-TFA-O-alkyl amino acid derivatives was studied on four different permethyl- andOpentyl-b-and -c-CD stationary phases
Many active drugs are racemic mixtures. Because the two enantiomers of a racemate often cause different pharmacological responses, the use of optically pure isomers is desirable and may be soon required. Cyclodextrin-bonded silica gel can be used as chiral stationary phase (CSP) in liquid chromatogr
