✦ Synopsis


The biochemical racemizations of amino acids in organisms which occur with aginglp4 and carcinogenesis5, and the geochemical racemizations of free and/or bound amino acids with diagenesi9, have been investigated. These studies require a handy technique for observing the racemization processes. Although methods for separating ' DL-amino acids have been reported -lo, they are not suitable for our purpose from the viewpoints of cost-performance, sensitivity and ease of operation.

The resolution of 2,4-dinitrophenyl(DNP)-DL-amino acids on a native cellulose column has been reported using conventional liquid chromatography1 l. We described here the resolution of sixteen DNP-DL-amino acids by high-performance liquid chromatography (HPLC) and its application to biochemical and geochemical studies.

We have studied the resolution of DL-amino acids on a native cellulose column. All the DL-amino acids related to protein and their 16 DNP-DL-amino acids were separated. The resolution capability depends mainly upon the bulkiness of the side group attached to the ␣-carbon, but also on structural and
