✦ Synopsis

The possibilities of separation of seven D,L-mixtures of amino acids on chitin, chitosan beds and their modifications are tested, using TLC methods. From investigated stationary phases chitin modified by Cu 2+ ions may be used for separation of optical isomers of amino acids. The best results have been obtained in chromatographic systems with ternary mobile phases.

## Abstract A systematic research was made into the conditions producing optimum separation of the optical isomers of amino acids by paper chromatography, using as pilot substances racemic mixtures of the amino acids histidine, tryptophan and kynurenin and methanol‐water mixtures as eluents. The op
