Resolution of amino acids by a native-cellulose column.
Seventeen aliphatic, hydroxyl, sulfur-containing, aromatic, imino, and heterocyclic DL-amino acids were resolved without derivatization using a native-cellulose column. Chirality was assigned by either CD spectra or co-chromatography. Under these conditions, it is known that the hydrophobic interaction of amino acids with the hydroxyl groups on the cellulose played an important role in the separations. The cellulose column chromatographic system for resolution of amino acid enantiomers was combined with an amino acid analyzer. Thus, the DL-amino acids separated by the latter system were successively resolved by the former.
