Vitamin C
Juráňová, Jana ; Hrstka, Miroslav (referee) ; Vespalcová, Milena (advisor)
The theme of this diploma thesis is an assessment of given nutritional parameters in selected kinds of lesser known fruits, specifically 10 varieties of sea buckthorn (Hippophae rhamnoides L.), 12 varieties of cornelian cherry (Cornus mas L.) and 6 varieties of blue honeysuckle (Lonicera caerulea var. kamtschatica). Harvests of two consecutive years (2011 and 2012) were analyzed in the case of blue honeysuckle. The theoretical part was focused on historical, morphological, taxonomic and nutritional aspects of individual plants and food or pharmaceutical utilization. The considerable part of the thesis is devoted to the characterization and the possibilities of determining the contained substances, namely ascorbic acid and polyphenolic compounds, especially anthocyanins. The content of the experimental part was a description of the methods and the results of the analysis of total solids, titratable acidity, total phenolics, total anthocyanins and ascorbic acid in fruits of the selected varieties of the above mentioned fruit species. Based on the measured results, the different varieties of fruits were compared to each other and evaluated.

Rybníčková, Eva ; Šalplachta, Jan (referee) ; Vespalcová, Milena (advisor)
This work speaks about the possibilities of using fruits of the blue honeysuckle (Lonicera camtschatica) in the food industry. The first part describes the properties of this plant and methods of its cultivation. The second chapter deals with the chemical composition of the fruits and the importance of nutritionally valuable substances contained in them. The third chapter assesses the current appearance of the fruits in the world in the commercial point of view and the possibilities of processing the fruits into products. The last part deals with the methods of isolation and determination of important substances in the fruits, namely anthocyanins.
