Abstract: Eighteen derivatives of six DLamino acid alanine, 2-amino-n-butanoic acid, va-line, leucine, phenylalanine, methionine of enantiomers were separated by L-isoleucine-t-butylamide type chiral bonded stationary phase (CSP) in HPLC. The experimental result showed that the chiral stationary phase had good resolution for the racemic α-amino acid derivatives. The performance of the structure of derivatives and composition of mobile phase for the resolution was examined. The probable mechanism for chiral recognition was proposed.
