Chemická charakterizace vín z vybraných PIWI odrůd / Chemical composition of wine produced from PIWI cultivarsMichálková, Kateřina January 2020 (has links)
This diploma thesis deasl with the chemical charakterization of wine from selected PIWI varieties. The theoretical part describes the general origin and reason for breeding PIWI varieties, a closer characterization of selected three PIWI varieties, Johaniter, Hibernal and Solaris. The next part is devoted to the description of analytical methods that were used to determine the chemical characteristics. The experimental part is developed to the determination of chemical characteristics, namely general characteristics such as alcohol, total phenols, phenolic substances, volatile substances and elemental composition. The results show that are differences between wines from selected PIWI varieties in therms of chemical composition. The most represented organic acid was in the range of 735,1-1286,2mg/l malic acid. This was followed by acetic in the range of 100-400mg/l. The antioxidant activity was determined in the range of 0,2988-0,9683 mmol/l of Trollox and content of total phenols 273,5-390,3mg/l. Of the phenolic substances, gallic acid was the most represented, ranging from 6,9-13,9mg/l. As another, abundant phenolic substances, catechin in the range of 1,6-6,0mg/l was detected. Of the determined elements, phosphorus in the range of 165,4-450,5mg/l was the most represented. Representatives of ethyl ester, ethyl acetate, decanoic acid ethyl acetate and hexanoic acid ethyl ester, were detected as the most abundant volatiles. From the measured data it was evident that wines from PIWI varieties different from standard varieties, especially in the profile of aromatic substances.

Analytická chemie odhaluje diverzitu a funkci chemických látek užívaných v komunikaci a obraně termitích společenstev / Analytical chemistry unravels the diversity and function of chemicals used for communication and defence in termite societiesKrasulová, Jana January 2015 (has links)
Analytical chemistry plays a crucial role in studies on chemical ecology and only the development of sophisticated methods enables the detection of biologically active compounds that are usually present in minute quantities and often in very complex mixtures. My thesis is dedicated to the application of modern analytical techniques and instrumentation to unravel the identity, chemical diversity and function of semiochemicals and defensive compounds used by various species of termites. The first section of this thesis aims at the identity of chemicals used in communication, the pheromones. I studied the chemistry of the trail-following communication in three selected species of termites. Besides the identification of (3Z,6Z,8E)-dodeca-3,6,8-trien-1-ol, the most frequent termite trail-following pheromone, as the trail-following pheromone in Psammotermes hybostoma (Rhinotermitidae), I participated in the description of two new structures, (10Z,13Z)-nonadeca-10,13-dien-2-one in Glossotermes oculatus (Serritermitidae) and syn-4,6-dimethylundecan-1-ol in Hodotermopsis sjoestedti (Archotermopsidae). We identified (3Z,6Z,8E)-dodeca-3,6,8-trien-1-ol to be the female sex pheromone in Psammotermes hybostoma, and syn-4,6-dimethylundecanal to be the male sex pheromone in Hodotermopsis sjoestedti. I also...

Syntéza koibacinů / Syntehsis of coibacinesKolská, Kristýna January 2014 (has links)
Development of new asymmetric processes is one of the objectives of catalysis in organic chemistry. These processes can provide access to chiral building blocks applicable in syntheses of various natural substances that can be used for medical purposes. One such process is the preparation of chiral homoallyl alcohols, which have been used for syntheses of variety of biologically active compounds. In view of the aforementioned, suitably substituted homoallyl alcohols could be used as intermediates in syntheses of koibacins A-D, which have a number of interesting biological properties. Natural koibacins A-D are metabolites isolated from the marine cyanobacterium Oscillatoria sp. that exhibits selective antileishmanial activity and potent antïinflammantory properties. Our synthetic plan is focused on an approach through the allylation of aldehydes, esterification, ring closing metathesis and finally cross metathesis with different lipophilic fragments. Key words: enantioselective allylation, asymmetric synthesis, natural compounds, coibacins.

Školní projekt s tematikou očkování pro 2. stupeň základní školy a střední školy / School project to theme vaccination to second grade of primary school and secondary schoolJechová, Markéta January 2014 (has links)
The school project to theme vaccination to second grade of primary school and secondary school This thesis deals with the theme vaccination, its history and principles. The process of immunization is typically made by the administration of vaccines, given in certain time intervals that are determined in accordance with the rules of law. Before vaccine administration, vaccine should be thoroughly checked to protect security of patient's health. Ongoing research and advanced development projects help fight against diseases to protect the human organism. One of the themes that plays role in the vaccination is the financing of research and development as well as financing immunizations itself. As vaccination is as important for adults as it is for children, providing all informations to students is very necessary. To reach this point succesfully, the teching project (described more specifically in this work) is one of the possible ways. However, as project itself has its advantages as well as disadvantages, specific attitude of students and teachers is required accordingly. There are three different projects on vaccinations topics described in the thesis. These three projects were realized in three types of schools: secondary grammar school, third class of central medical lyce and eight class of...
