Analysis of sensorially active substances contained herbal extracts
Koloničná, Markéta ; Vítová, Eva (referee) ; Mikulíková, Renata (advisor)
The peppermint (Mentha piperita), the salvia (Salvia officinalis), the lemon balm (Melissa oficinalis), the camomile (Matricaria chamomilla) and the valerian (Valeriana officinalis) are herbs with healing effects. Their ethanol extracts are used for food fortification or in a cosmetic industry. Substances contained in herbal extracts were analyzed in this thesis. The extracts were prepared by maceration. Next, they were analyzed by using a gas chromatography and a mass spectrometry. The aim of this thesis was an optimalization of the method used for the analysis of sensorially active substances. Then, herbal extracts were analyzed and concentration of sensorially active substances was determined.

Studium vybraných fyziologických vlastnosti populací polních plevelů z odlišných stanovišť
Frantová, Nicole
The diploma thesis: Study of Selected Physiological Features of Field Weed Populations from Different Habitats investigates the effects of temperature and habitat influences on seed germination of redroot pigweed Amaranthus retroflexus and German chamomile Matricaria chamomilla. Seeds of redroot pigweed were collected from the habitats: field margin, tree alley, railway and field. Seeds of chamomile were collected from the habitats: field margin, tree alley and were also bought. The seeds were exposed to temperatures 6 °C, 8 °C and 18 °C.The highest seed germination of both species was at 18 °C and the lowest was at 6 °C. The highest seed germination of redroot pigweed was recorded from the „field margin“ habitat 34,67 % and the lowest seed germination from the „field“ habitat 28,67 %. The highest seed germination of German chamomile was recorded from the „bought“ habitat 86,67 % and the lowest seed germination from the „field margin“ habitat 34 %.

Pěstování léčivých rostlin z čeledi Asteraceae
Synková, Lucie
This bachelor thesis is focused on the topic Growing medical plants from Asteraceae family. Medical plants have been used in ancient times. Recently, their popularity is increasing. Asteraceae is one of the largest family of higher plants. Plants from this family are used not only in pharmacy, but also in cosmetic industry and food industry or in the process of liqueur making. In this thesis is described characterization of Asteraceae family, as well as characterization of medical, aromatic and spice crops. Furthermore, various active ingredients contained in medical plants and their effect on the human organism and general rules for growing medical plants are described. Next chapter describes growing of selected species from Asteraceae family, substances contained in medical plants from this family and posibilities of their utilization. Emphasis was put on growing chamomile (Matricaria chamomilla L.) and marigold (Calendula officinalis L.).

Variabilita obsahu silíc u vybraných druhov liečivých, aromatických a koreninových rastlín
Boško, Rastislav
Bachelor theses is themed "Variability in the content of essential oils in selected plants used in herbal medicine, aromatic plants and spice plants" and deals with the variability of the content of essential oils in caraway (Carum carvi L.), where carvone and limonene are present, in chamomile (Matricaria recutita L.), which contains farnesene, chamazulene, bisabolol oxide A and apigenin-7-glucoside, and in lavender (Lavandula angustifolia), which contains camphor, borneol, alpha-terpineol and linalylacetate. The thesis consists of two parts -- the first one is a literature review of selected plants and the second one is a practical part held in the laboratory at Department of Crop Science, Breeding and Plant Medicine at Faculty of Agriculture. In the practical part, drugs were individually analyzed using the methods taken from Czech pharmacopoeia. Samples from caraway were acquired from Agritec, s.r.o. company's breeding, lavender and chamomile came from the company Leros, s.r.o. and also from domestic production. Variation analysis of caraway proves that content of both examined substances -- carvone and limolene -- was highly affected by its genotype. Total content of essential oils, on the other hand, was not statistically affected by genotype. Four different variants were studied in chamomile. The content of essential oils in chamomile was statistically highly affected by monitored variants; the content of chamazulene was affected in the same way. Bisabolol oxide A was significantly affected by the variant of chamomile and so was apigenin-7-glucoside. Farnesene was not significantly affected by variant. All compounds found in lavender's essential oils, namely camphor, borneol, alpha-terpineol and linalyl-acetate, were statistically greatly affected by variant.
