Přehled fenolových látek v bylinných čajích
Holčíková, Dagmar
The topic of my bachelor thesis is Overview of phenolic compounds in herbal infusions. The first part of work describes the types of tea from the leaves of Chinese Tea (Camellia sinensis). The next part is focused on herbal drugs and their classification. For selected drugs are mentioned the substances and therapeutic effects. The next section describes the most important substances in herbal infusions, namely minerals, terpenes, vitamins, alkaloids, and the phenolic compounds are characterized by the most. The work deals mainly with their classifications, gives a brief description, and mentions the most famous representative of each group of phenolic compounds. The experiment determines the content of phenolic compounds and vitamin C in berries of the sea buckthorn (Hippophae rhamnoides).

Využití méně pěstovaných ovocných druhů pro zpracování
Vincentová, Martina
Bachelor thesis is focused on the possibility of growing and processing Chinese hawthorn (Crataegus pinnatifida Bunge.) and Chinese jujuba (Ziziphus jujuba Mill.). The origin, morphological description, cultivation, ecological requirements, propagation, harvest, health effects and food utilization of these fruit trees is described in this thesis. Japanese persimmon (Diospyros kaki Thunb.), Asian pear (Pyrus pyrifolia (Burm.) Nak. 'Hosui'), Hardy kiwi (Actinidia arguta (Siebold & Zuccarini) Planch. Ex Miq.), Sea buckthorn (Hippophae rhamnoides L.) and Mountain-ash (Sorbus aucuparia L. 'Sorbinka') are describe too. From the harvested fruits were produced conserves, marmelades and other products, which have been assessed during the tasting. Top rated was a jelly with hawthorn and hardy kiwi, then marmalade from jujuba, rowan berries and compote from jujuba and hawthorn with alcohol. Based on the evaluation was found that all products were evaluated above average. Products have positive sensoric qualities, significant health effects and are easy to produce. Therefore, the possibilities of domestic production are very wide.

Růstová charakteristika souboru odrůd rakytníku řešetlákového
Špačková, Petra
The aim of this thesis was to make a literature résumé relating to the origin enlargement of the sort, conditions for growing and usage of the fruits. It was a 'Sluníčko', 'Aromat', 'Krasavice', 'Leicora', 'Hergo', 'Polmix', 'Trofimovský', 'Vitamínová', 'Buchlovický 1', 'Buchlovický 2'. The experiment was conducted in the autumn of 2014 at the School farm in Žabčice (ŠZP ŽABČICE). For each variety were detected signs of growing on the above ground parts of the bush. Height, width and length were measured. Also the cubic capacity was calculated. All the data were recorded and analyzed in Microsoft Excel and Statistica 12. And also branching shape shrubs and number of thorns has been considered.

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.

Determination of C vitamin by HPLC in fruits of individual cultivars of less known kinds of fruits
Cetkovská, Jitka ; Vránová, Dana (referee) ; Vespalcová, Milena (advisor)
Diploma thesis deals with determination of vitamin C in various cultivars of sea buckthorn (Hippophae rhamnoides, L.) and quince (Cydonia oblonga, Mill.). In theoretical part, there are mentioned basic information about these less known fruit species, their medically significant substances and utilization of these fruits. Various methods for determination of vitamin C are discussed with focus on HPLC and extraction of vitamin C from the matrix. In experimental part, the most suitable column (Gemini C18, 150 x 4,6 mm; 5 m) was chosen from six various columns. Analysis of vitamin C in various cultivars of quince and sea buckthorn fruits were carried out on this column. The various types of matrix preparation and two different separation systems (method with oxalic acid and system with phosphate buffer and methanol as a mobile phases) were investigated too. Vitamin C was determined as an ascorbic acid.

Properties and utilization of Sea-buckthorn oil
Trávníčková, Eva ; Kučerík, Jiří (referee) ; Zemanová, Jana (advisor)
This bachelor thesis deals with the properties and utilization of sea buckthorn (Hippophae rhamnoides) and sea buckthorn oil. Sea Buckthorn oil contains wide range of substances important for health, for example vitamin E, vitamin A, carotenoids, flavonoids, sterols and essential unsaturated fatty acids. Sea Buckthorn oil is commonly used in treatment of cardiovascular disease and cancer. Its antioxidant properties are of great importance; it has UV-blocking activity and anti-aging effects. It accelerates healing of injuries and burns. In this work there are methods of thermal analysis such as differential scanning calorimetry (DSC) and thermogravimetry (TG) are employed and described. These methods were used to study thermal and thermo-oxidative stability and physical-chemical behavior of the sea buckthorn oil. DSC method was used in the slow and rapid cooling regime which revealed the sensitivity of oil to the thermal history and also the fact that the resulting endotherms do not correspond to melting temperatures of sea buckthorn oil pure components. Application of TG method revealed that oxygen has only minor effect on thermo-oxidative stability; degradation of sea buckthorn oil is caused mainly by the elevated temperature.

Charakteristika a možnosti využití rakytníku řešetlákového
Stuchlíková, Veronika
Bachelor thesis is focused on options of cultivating and processing of fruits of sea-buckthorn (Hippophae rhamnoides), which is not fully appreciated even nowadays. It gives an overview of origins and spread, typical features and modes of reproduction. It further describes difficult harvest, characteristics of varieties, diseases and pests. Experimental part describes growing features of four varieties (Buchlovický 1, Hergo, Leicora, Vitamínová), which are situated in the research center of Mendeleum in Lednice. Subsequently varieties suitable for growing in the Czech Republic are recommended. Canned and other products were made of harvested fruits and evaluated by respondents. On the basis of the given score was found that the sea-buckthorn oil had the highest response of respondents and conversely, the sea-buckthorn fruit with garlic had the lowest response.
