Evaluation of Corporate Performance for the Sustainable Development Support
Smoroň, Samuel ; Pavláková Dočekalová, Marie (referee) ; Chvátalová, Zuzana (advisor)
Diploma thesis is focused on the evaluation of the performance of a selected company operating in the field of processing medicinal plants and natural substances for the period 2015 - 2020. The tools of financial analysis are used in the evaluation. The calculation and results are realized and displayed using Maple software. Selected company indicators are compared with the industry average. The analysis of PESTLE and Porter's model is processed in the work. The performed analyzes are used in the design to improve the company's performance and outline the parameters for the implementation of the Balanced Scorecard method, which should be a supporting tool for ensuring the sustainable development of the company.

The antimicrobial effects of plant extracts against yeast skin mycoses
Posztósová, Gyöngyi ; Rapta, Marek (referee) ; Němcová, Andrea (advisor)
Superficial cutaneous mycoses are relatively widespread and affect more and more people. Currently are used drugs as ketoconazole, fluconazole and others to treat mycoses. Pathogens occasionally become resistant to these drugs. Medicinal plants have a long history in alternative medicine and they could be a good solution. This bachelor thesis deals with the study of antifungal activity of selected plants. Were prepared ethanol extracts of basil, betony, eucalyptus, turmeric, geranium, oregano and ginseng. The theoretical part of thesis contains a review of the most frequently occurring dermatomycoses. It describes plants as sources of natural substances with antimicrobial effect and the content of selected active substances. The experimental part is focused on the analysis of plant extracts. Was determined the content of total polyphenols, flavonoids and antioxidants. The antimicrobial activity was monitored against yeast Candida glabrata and against G- and G+ bacteria, specifically Escherichia coli and Micrococcus luteus. Finally, the cosmetic products with the addition of plant extract were prepared and tested against mycoses.

Srovnání antioxidačních vlastností a absorbce UV záření u extraktů vybraných bylin, Spiruliny a jejich směsí
Farinasso, Giulia
This study aimed to compare the antioxidant properties and UV radiation absorption of se-lected herbal extracts, blue-green algae spirulina extract and their mixtures. Extracts were ob-tained by ultrasound assisted extraction. The total polyphenol (TPC) and flavonoid contents (TFC) were determined, and the Trolox equivalent antioxidant capacity (TEAC) was meas-ured. The best antioxidant properties has been showed by C. officinalis individual extract and its mixture with spirulina. Additionally, the UV-absorbing substances at 355 nm were quanti-fied. The extracts from C. officinalis and S. nigra were further analysed for their rutin content by HPLC-DAD. The rutin content in S. nigra and C. officinalis extracts was found to be 1935,97 ± 98,39 μg.g-1 and 233,035 ± 8,839 μg.g-1 of dry weight of flos, respectively. The highest content of phenolic compounds was found in the S. nigra extract, and the highest total antioxidant capacity was determined for the C. officinalis extract. Pearson's correlation re-vealed that the overall antioxidant capacity and UV absorption results were significantly cor-related with the total phenolic compound content only for the elderflower extract. The syner-gistic effect of the herbs used in combination with spirulina was evaluated.

Škůdci volně rostoucích a pěstovaných hluchavkovitých léčivek
Kočicová, Anna
I observed pests of Lamiaceae medicinal plants by visual inspection in the growing season of 2022 on two experimental areas. The first experimental area was the MENDELU arboretum, the second was the garden in Boleradice. 30 species of plants were monitored in area 1 (MENDELU arboretum) and 10 plant species in area 2 (Boleradice). A total of 711 individuals, 31 pest species, from 4 orders and 18 families were detected. 20 species of insects belong to the order of Hemiptera, 9 to the order of Coleoptera, 1 to the order of Orthoptera, and 1 Dermaptera. Aphids were the most nu-merous taxon (137 individuals). The representation of polyphagous, oligophagous and monophagous phytophages was almost identical on both experimental plots: polypha-gous 56–57%, oligophagous 42%, monophagous 1–2%. Phytophagous species detected on Lamiaceae plants reached a higher occurrence in the MENDELU arboretum than in Boleradice. No phytophages were detected on Salvia splendens, Nepeta cataria, Galeopsis segetum and Ocimum basalicum. The most attacked plant was Ballota nigra (104 individuals and 14 species). The monitored Lamiaceae plants were not seriously damaged, and therefore it was not necessary to use any regulatory measures against pests.

Herb garden and its connection with environmental education in kindergarten
BERANOVÁ, Iveta
The subject of the bachelor's thesis on the topic of "The herb garden and linking it to environmental upbringing at nursery school" is the introduction and definition of individual terms associated with environmental upbringing necessary for the draft and creation of a project on this topic and its actual realisation. The theory section of the thesis also presents an overview of legislation in the area of environmental upbringing and education introducing possible types of herb gardens, individual specifics of the cultivation of medicinal plants, their effects and safe use from the point of view of pre-school education. The practical section of the thesis consists of the stage of preparation, realisation and evaluation of the education programe. The stage of the preparation and realisation of the project contains activities associated with topics aimed at specific types of herbs in nursery school. The final practical area is the stage of evaluation rating the level of success of the actual practical teaching and suggestions for its improvement.

NADP-dehydrogenases of medicinal plants.
Bartošová, Martina ; Hýsková, Veronika (advisor) ; Kubíčková, Božena (referee)
Medicinal plants usually contain metabolites formed by secondary biosynthetic pathways for example phenylpropanoid and shikimate pathway, which depend on NAPDH availability. In this work total content of phenolic compounds and flavonoids was determined in 10 medicinal plants common for Czech Republic. Activity of enzymes providing NADPH was determined as well. These enzymes were glucose-6-phosphate dehydrogenase (G6PDH, EC 1.1.1.49), NADP-isocitrate dehydrogenase (NADP-ICDH, EC 1.1.1.42), NADP-malic enzyme (oxalacetate decarboxylating) (NADP-ME, EC 1.1.1.40). The activity of shikimate dehydrogenase (SDH, EC 1.1.1.25), the main enzyme of shikimate pathway, was also determined. Extraction methods were optimized for each assessment. Applicable source for NADP-dependent enzymes are black radish (Raphanus sativus L. var. niger), garlic (Allium sativum L.) and mint (Mentha piperita L). The highest content of phenolic compounds and flavonoids was determined in sage (Salvia officinalis), lemon balm (Melissa officinalis L.) and Mentha citrata. Extraction with methanol was more effective than extraction with hot water. More extraction methods and studies are necessary for characterization of individual compounds and principals on which they work. Key words: medicinal plants, NADP-dependent enzymes, phenolic...

Ecology of orchids and other potential pharmaceutical plants in Nepal
Rokaya Timsina, Binu ; Kindlmann, Pavel (advisor) ; Whigham, Dennis (referee) ; Kull, Tiiu (referee)
In this thesis, I focused mainly on orchids and also carried out some research on different pharmaceutically potential plants in Nepal. I compiled both data from field and secondary data sources and one of my first outputs was complete checklist of orchids in Nepal. I also studied distribution patterns and affinities of orchids with different floristic regions in Nepal. My next work on epiphytic orchids is related to diversity, distribution and host- species associations and their future in the context of climate change in Nepal. In addition to this, I also worked on factors affecting epiphytic orchids along an altitudinal gradient in central Nepal. Working on population dynamics of terrestrial orchid species, Crepidium acuminatum, lasted for 6 years. Together with orchids, I determined secondary compounds present in a highly important Nepal endemic medicinal plant, Swertia multicaulis. I also compiled the information on uses, phytochemistry, pharmacology and toxicity of highly important Himalayan endemic medicinal plant, Neopicrorhiza scrophulariiflora. The last research of my Ph.D. project ended up by gathering the information on uses of different medicinal plants, including orchids that were used to treat various gastrointestinal diseases in Nepal. The results of my doctoral thesis are presented...
