Flavonoidy v druzích čeledi Lamiaceae
Fiala, Jonáš
In this bachelor thesis were described flavonoids, their chemical structure, properties and significance. Furthermore, the morphology of the genera Mentha L., Salvia L. and Origanum L. was described with a focus on the correct taxonomic classification and brief characteristics of the varieties. From the literature and scientific articles was collected informations about the content substances of individual taxa with a focus on flavonoids, their content, effects and factors that influence their content and quantity.

Rod Salvia L. - historie a současnost pěstování
Štípalová, Nikola
The aim of the thesis was to describe genus Salvia L. consisting of 900 species, which constitute the biggest genus in family Lamiaceae. First of all there is reported characteristics typical for the family and genus. Following summary of historical background, extension and origin of genus Salvia L. Next chapters are dedicated to demands of growing, pests and diseases, even when there are only few of them. And also to propagation of sages. Thesis also outlines chemical constituents and possibilities of breeding either for an increase of chemical constituents or another plant features. Furthermore the thesis describes large range of sages along with options of use in various industries, naming products which are made of salvia, and also describing current situation in production of this plants.

Content of selected phenolic compounds in spice plants.
BERANOVÁ, Zuzana
This work concerns the amount of certain phenols in some of the representatives of families Alliaceae, Lamiaceae and Apiaceae. Phenols in plants are widely represented and highly concentrated. Flavonoids are one of the smallest, yet quite significant classes of phenols. Ingestion of food containing flavonoids can prevent certain diseases such as Arteriosclerosis. cardiovascular and tumor diseases. This work focuses, for their special biological effects, on five flavonoids: Kaempferol, Quercetin, Myricetin, Apigenin and Luteolin. For determining the content of phenols a method of High-performance liquid chromatography (HPLC) was used. Three representative of the family Alliaceae, two representatives of the family Lamiaceae and three representatives of the family Apiaceae were analysed. Only edible parts of the plants were used for the analysis and the amount of phenols was compared in certain plants planted in beddings to the plants planted in greenhouses. At first, the qualitative representantion of phenols was ascertained by the HPLC method. The result is chromatographic profiles, which were then used in calculating the amount of particular phenols. Then the total amounts of kaempferol, quercetin, myricetin, apigenin and luteolin were found out thanks to HPLC method. The biggest amount of total kaempferol was determined in petroselium hortense planted in beddings (588 mg/kg of fresh sample) and in a greenhouse (340 mg/kg of fresh sample). The biggest amount of quercetin was determined in red onion planted in a greenhouse (773 mg/kg of fresh sample) and in ocimum basilicum planted in beddings (535 mg/kg of fresh sample). The biggest amount of apigenin was determined in petroselium hortense planted in a greenhouse (1790 mg/kg of fresh sample) and in petroselium chrispum planted in beddings (3690 mg/kg of fresh sample).
