Využití vysokoúčinných separačních metod pro chirální i achirální separace / The application of high-efficiency separation methods for chiral and achiral separationsŠubová, Martina January 2019 (has links)
In the first part of the doctoral thesis, the capillary electrophoresis was used to test the potential chiral separation properties of monosubstituted cyclodextrin derivatives, namely PEMEDA- and PEMPDA-β-cyclodextrins for the group of selected analytes. Both selectors exhibited excellent enantioseparation properties for N-boc-D,L-tryptophan, where the enantiomers were completely separated even at 0.5 mmol·l-1 concentration of the cyclodextrin derivative in the background electrolyte. However, the differences between the enantiodiscrimination properties of individual derivatives were minimal. The second test group consisted of two cyclodextrin derivatives, namely 2-O- and 3-O- cinnamyl-α-cyclodextrins. These derivatives are able to form supramolecular polymers in aqueous solutions that disintegrate at elevated temperature. The formation of these polymers was tested by NMR and DLS experiments. None of the tested cyclodextrin derivatives showed enantiodiscrimination properties towards a group of selected analytes. In the frame of antipredatory study, HPLC-MS/MS method working in HILIC mode was used for separation of ten pterin derivatives and riboflavin, which can be present as pigments in insects, reptiles or amphibians as a part of their warning coloration. The developed methodology was applied for...
