چکیده انگلیسی
A new analytical methodology was developed by EKC enabling the fast enantiomeric separation of Ornithine in complex mixtures of amino acids. A previous derivatization step with 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (AQC) was achieved to enable the sensitive UV detection of amino acids as well as to make possible their interaction with the CDs employed as chiral selectors. A dual CD system containing an anionic and a neutral CD in phosphate buffer at acid pH showed a high resolving power allowing the enantiomeric separation of 18 protein amino acids and Orn. The method was applied to the analysis of fermented foods to investigate the extent of the presence of Orn enantiomers.
