Aspects of the use of herbal preparations adult population in the Czech Republic
Knotek, Karel ; Kokoška, Ladislav (advisor) ; Zelený, Václav (referee) ; Jahodář, Luděk (referee)
The subject of this thesis is to map the approach and behaviour of the adult population in the Czech Republic as regards the use of plant products (PP), both medicinal plants and herbal dietary supplements. For the public, the high prevalence of PP is a good opportunity to use such plants for self-medication or to prevent illness. The general part of this thesis describes the characteristics and importance of both groups of plant products, as well as the topical issue of the choice, use and role of these plants in the world and in the Czech Republic on the basis of research. The practical part then presents the results of a questionnaire survey of people who use plant products - customers of pharmacies in selected regions of the Czech Republic: the capital, Prague, the Region of North Bohemia, and the Region of South Bohemia. Based on classification attributes the work monitors the public's approach and behaviour as regards the choice and means of acquiring and using PP and activity in relation to self-medication, such as consulting the suitable selection of PP or people informing their doctor that they are using PP. The work ascertains to what extent users know about and are aware of medicinal plants, how they are collected and used, and their properties on which the respondents base their choice...

Biologically active substances of medicinal plants within selected families (Rosaceae, Lamiaceae and Asteraceae)
Čápová, Klára ; Vodičková, Hana (advisor) ; Zelený, Václav (referee)
For ages plants have not only been used as a source of food but also to prevent or treat various diseases. Their healing effects are provided by biologically active substances, especially the products of secondary metabolism. Primary metabolites, such as carbohydrates, lipids and proteins, are particularly important from the nutritive point of view. They are an essential part of our diet. The same level of importance also applies to vitamins that serve as catalysts in a great number of metabolic reactions.
The aim of this thesis was to describe biologically active substances found in medicinal plants of the Rosaceae, Lamiaceae and Asteraceae families and to summarize their effects on human health. These families include many species of plants that have demonstrated positive effects on human health. The effects are mainly attributed to phenolic compounds, most of which are represented by flavonoids, phenolic acids and tannins. Furthermore, essential oils and vitamin C also have a positive impact on our health.
Medicinal plants from the previously mentioned families often have astringent, spasmolytic and antimicrobial properties, for which they owe to phenolic compounds, especially tannins, flavonoids and phenolic acids. Due to the content of essential oils and their spasmolytic effects they counteract cramps and diarrhoea, increase the production and secretion of bile and also have antimicrobial effects. Plants that contain vitamin C, an important antioxidant, can boost our immunity in general.
Another aim of this work was to define external factors that can influence the content and the metabolism of biologically active substances. Considering climatic conditions we have to mention temperature and light, which primarily influence the content of essential oils. Other factors could be soil composition, methods of cultivation, harvesting and post-harvest processing. During the process of drying there comes the loss of essential oils and vitamin C.
The integral part of this thesis was also to create an overview of selected medicinal plants of the Rosaceae, Lamiaceae and Asteraceae families, thein plant-based drugs, biologically active substances and their effects on human health.
