Abstract: The thesis deals with the use of electrophoretic methods in the analysis of pharmaceutically important compounds. In the theoretical part, the principles of basic techniques (like CZE, MEKC, ITP etc.) as well as on-line preconcentration methods (stacking, sweeping, ITP-CZE, tITP) are described. The first part of the experimental work deals with the use of on-line sample preconcentration techniques (ITP-CZE and LVSS with polarity switching) for the analysis of the complex matrices of plant origin. 1. The on-line ITP-CZE was used for the separation and quantification of phenolic acids derived from benzoic and cinnamic acids in methanolic extract of Epilobium parviflorum. BGE-S-BGE electrolyte system was used for the separation. The leading electrolyte in the ITP pre-separation step was 0.01M HCl, 0.02M imidazol, 0.2% HEC with pH 7.2; the terminating electrolyte was 0.01M HEPES with pH 8.2. The background electrolyte in the electrophoretic step contained 25mM MES, 50mM TRIS, 30mM boric acid, 10mM α-cyclodextrine, 0.2% HEC of pH 8.3. A single analysis took 25 min. No special sample pretreatment was required. 2. The next work focused on the application of a stacking-CZE method used for the separation and determination of eight phenolic acids in an extract of Epilobium parviflorum. Large-volume sample stacking...
