Autor: Naoko Kisu, Yasuhiro Matsushita, Hajimu Kitahara, Naobumi Ôi

Publikováno v: Journal of Chromatography A. 722:229-232

Excellent enantiomer separation of a variety of racemic compounds, including alcohols, amines, amino alcohols, carboxylic acids, hydroxy acids and amino acids, was achieved by GC and HPLC with tripeptide derivatives, containing L-valyl-L-valyl-L-vali
