Sažetak
In recent years enantioseparation of both active pharmaceutical ingredients and bio molecules
such as amino acids became more and more necessary because in most cases the two stereo forms exhibit
different pharmacological effects. This article deals with the chiral separation of dansylated amino acids
by ligand-exchange capillary electrophoresis using L-phenylalaninamide, L-lysine and L-threonine as chiral
selectors. Experiments with different central metal ions such as Cu(II), Co(II), Cd(II), Ni(II) and Zn(II)
were carried out. Optimal conditions were found out by studying the effect of the pH and the selector molarity
on the chiral resolution. Best separation was obtained for the Cu(II)/L-lysine complex, showing a
chiral resolution up to 17 for Dns-DL-Met. (doi: 10.5562/cca1762)
