Influence of genotype on rutin content in plants from genus \kur{(Fagopyrum)}
KRÁLOVÁ, Martina
The bachelor work is focused on evaluation of the influence of buckwheat species and variety on rutin containt in particular plant parts, on the total rutin yield per hectare production and on comparison varietal differences between both species, common buckwheat \kur{(Fagopyrum)}esculentum)} Moench) and tartary buckwheat \kur{(Fagopyrum tataricum)}. Rutin is a flavonol (quercetin-3-O- rutinosid) which is also called P vitamin. As well as it is known as the permeability factor or factor allowing permeability of the blood vessel. Rutin stimulates the C vitamin effect. Rutin has as well a high influence on hypertension, hypercholesterolemia and other cardiovascular diseases due to antioxidant properties. Buckwheat is the most important source of rutin. It is annual plant which belongs to Polygonaceae family and has a beneficial effect on human body. The common grown type is common buckwheat \kur{(Fagopyrum)}esculentum)} Moench) and less used type is buckwheat tartary \kur{(Fagopyrum tataricum)}. Tartary buckwheat \kur{(Fagopyrum tataricum)} contains several times higher amount of rutin than common buckwheat \kur{(Fagopyrum)}esculentum)} Moench). The highest amount of rutin is presented in the leaves and blossoms and the lowest one in seeds. Tartary buckwheat \kur{(Fagopyrum tataricum)} has much higher amount of rutin in seeds than common buckwheat \kur{(Fagopyrum)}esculentum)} Moench). The varietal differences in rutin content are considerable.

Enantiomer separation and determination of helix inversion barrier of helical dications by capillary electrophoresis
Koval, Dušan ; Adriaenssens, Louis ; Severa, Lukáš ; Teplý, Filip ; Sázelová, Petra ; Kašička, Václav
Enantiomeric helical forms of dicationic helquats, a novel family of charged helicene-like molecules, have been separated by capillary electrophoresis (CE) using sodium-phosphate buffer, pH 2.5, as background electrolyte and sulfated beta- and gamma-cyclodextrins as chiral selectors. Additionally, CE was used to determine barrier to helix inversion of helquats.

Fyzikálně-chemická charakterizace peptidů a bílkovin kapilárními elektromigračními metodami
Kašička, Václav ; Koval, Dušan ; Šolínová, Veronika ; Sázelová, Petra ; Prusík, Zdeněk
High-performance capillary electromigration methods, zone electrophoresis, isotachophoresis, isoelectric focusing, affinity electrophoresis and electrokinetic chromatography, are presented as powerful tools for physicochemical characterization of peptides and proteins.
