Podlipná, J. Phytochemical study of Helianthus annuus L. IV. Diploma thesis 2008. Charles University in Prague, Faculty of Pharmacy in Hradec Králové, 93 pp. The thesis was focused on phytochemical research of plant Helianthus annuus L. The aim of the research was to obtain new information about plant metabolites of sunflower. There was an effort to evaluate the quality of included compounds in sprouts and sunflower seed shells and to divide ethanolic extract from leaves of this plant. Finally the evaluation of biological activity was done from fractions of leaves and shells. There weren't detected any alkaloids in extract from sprouts. Caffeic acid was detected in sunflower seed shells according to thin-layer chromatography. 80% ethanolic extract from sunflower leaves had significant antioxidant activity which was measured both by DPPH radical and FRAP method. Fat acids were found in fraction No. 14 (from 2nd chromatographic column of extract from leaves). Extract from leaves was toxic for worms Tubifex tubifex Müll. but it wasn't phototoxic.

Podlipná, Jana ; Karlíčková, Jana (advisor) ; Kašparová, Marie (referee)
Podlipná, J. Antioxidant activity of Helianthus annuus L. constituens. Rigorous thesis 2009. Charles University in Prague, Faculty of Pharmacy in Hradec Králové, 58 pp. Rigorous thesis follows the Diploma thesis Phytochemical research of Helianthus annuus L. IV. The thesis was focused on testing of biological activity of extracts and fractions from plant H. annuus. Setting-up the total amount of phenol substances with Folin-Ciocalteu reagent on chosen extracts and fractions was done. Further the antioxidant activity was evaluated by DPPH radical on various extracts and fractions from this plant and antimycotic activity on 12 testing strains of fungi clans as well. The new findings about sunflower were added into thesis at the end. The highest content of phenol substances from tested extracts and fractions were in 80% ethanol extract from leaves of sunflower (0,084 mg GAE/mg of dry extract). Chosen fractions gained from 80% ethanol extract from leaves of this plant did not showed significant antioxidant activity. Kaurenoic acid gained from ray flowers and fractions from pericarp did not showed antimycotic action on tested strains.

Controlling
Podlipná, Jana ; Mikovcová, Hana (advisor) ; Biško, Jan (referee)
Documentation of business processes and results of operations including storing the entries in data warehouses inherently belongs to the current requirements for corporate governance. But still more valuable is the ability to process the collected data into information that is used daily as a basis for management decisions at all levels of corporate management. This thesis deals just with form and methods of organizing information into standardized reports, whereas the object of analysis is a separate internal department within a selected company. The aim of this work is a detailed analysis of department reporting, assessment of its informative quality, utility and benefit for users. The theoretical part includes methodological bases and general principles for creating reports. Content of the practical part is an entire description of standard reports with a focus on application of controlling methods, usage of reported data and detection of weaknesses. In conclusion part there was evaluated overall level of analyzed reporting system, there were summarized circumstances that affect its present-day form, and proposed additional indicators, that could enrich the current concept.
