Determination of substances content in mint
Novotná, Martina ; Zlámalová Gargošová, Helena (referee) ; Vávrová, Milada (advisor)
This Bachelor thesis deals with determination of the content substances in mint (Mentha). Mint is in pharmacy very popular herb, it is been used for over 2000 years. We know many species of mint. Peppermint (Mentha piperita) is the most favorite and most common species. In the theoretical part there is description of substances found in plants, the characteristic of mint and principles of used analytical methods. Practical part of this thesis describes substances found in examined teas.

Compounds of terpenic nature in mint plants and the influence of elicitation on them
Jančová, Nikola ; Čáslavský, Josef (referee) ; Vávrová, Milada (advisor)
Diploma thesis is focused on study of compounds of terpenic nature in mint plants. Terpenic compounds are volatile hydrocarbons formed by several isoprenoid units with low molecular weight which cause the typical smell of plants. Presence of these compounds cause that plants seem to be fungicidal, bactericidal and insecticidal. Due to these properties, they can be used as botanical pesticides which are not toxic and no resistant organisms occur. Each plant contains relatively low concentrations of these compounds and therefore elicitors must be used for the increasing of terpenes amount. Elicitors activate defensive mechanisms in the plant leading to higher defense abilities and production of secondary metabolites. The identification and quantification of analytes was determined by gas chromatography in connection with mass spectrometry.

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.
