Štěpánová, Zuzana ; Spilková, Jiřina (advisor) ; Dušek, Jaroslav (referee)
1. Abstract Purpose of this thesis was to prove and determine antioxidant activity of flower extracts from black elder (Sambucus nigra L.) and compile summary of their content substances and effects. Sambuci flos is often used in natural therapy and food industry. The main content substances are flavonoids, phenolic acids, triterpenoids, further are contained in flowers sterols, mucilage, essential oils, tannins. Flavonoids are the most significant, specifically rutin and kvercetin, because they can show antioxidant, antiviral, anti-inflammatory and anticancer properties. Flowers are used mainly for their diuretic, diaforetic, expectorant, analgetic effects. Method DPPH (2,2-difenyl-1- pikrylhydrazyl) was used for determination antioxidant activity of methanolic flower extracts. Results of antioxidant activity were expressed as IC50 values (concentration of extract which causes 50% reduction of radical). The average observed IC50values were 0,79 mg/ml and 0,83 mg/ml. The individual IC50values have changed fluently during development of flowers, they range from 1,086 mg/ml and 0,701 mg/ml in both collections. Deviations can be caused by ongoing synthesis of the secondary metabolites.

The aim of the thesis was to find out how domestic violence was framed in the Czech printed media.

The work brought about a theoretical introduction into the concept of framing which became a part of the media studies in the last twenty years and which currently deals with all phases of media text origination and interpretation. The framing method was applied on a chosen topic of domestic violence, in connection with the new law on protection of abused people, which came into effect on January 1, 2007. Five weeklies (Blesk pro ženy, Instinkt, Květy, Reflex, Respekt) were selected for analysis and the monitored period of one calendar year from January 1, 2007, to January 1, 2008, was set. In the practical part, a qualitative analysis was carried out, determining the frames and research hypotheses for further interpretation of framing of given topic. Subsequent quantitative analysis studied the methods of article framing by individual magazines and eventual differences in the approach to this topic from the viewpoint of prevailing stereotypes associated with domestic violence. Attention was also paid to the question whether the magazines provided...
