Antimicrobial substances from plants and their application in acne preparations
Alexová, Adéla ; Byrtusová, Dana (referee) ; Němcová, Andrea (advisor)
The aim of the bachelor thesis is a determination of selected active substances of various plants and their possible application in cosmetic products for acne. In the theoretical part, an inventory of active substances including their effects in cosmetic products has been developed. Furthermore, the work is focused on characteristics of certain types of plants, mechanisms of antimicrobial effects and the emergence and treatment of acne. In the experimental part of this work the contents of biologically active substances, antioxidant and antimicrobial activity in extracts from selected plant species are characterized, namely from flowers of Levandula angustifolia, Matricaria chamomilla, Calendula officinalis, Syzygium aromaticum, leaves of Salvia officinalis and leaves of Rosmarinus officinalis. The plant extracts are also tested in different mixtures. Plant extracts and mixtures are incorporated into a recipe of acne cosmetic products. Their inhibitory effect against Propionibacterium acnes which causes acne and against representatives G+, G- and yeast Micrococcus luteus, Escherichia coli and Candida glabrata is observed. From the results it is clear that the best products against acne are micellar water and possibly skin lotion. The biggest amount of active substances is in cosmetic products which contain Matricaria, Syzygium and Rosmarinus. Overall effect of active substances is lower in cosmetic products than in 100% extracts.

Preparation of microbial, plant and algal extracts to use in cosmetics for infants
Janderová, Šárka ; Dzurická, Lucia (referee) ; Márová, Ivana (advisor)
This bachelor thesis deals with the preparation of a cosmetic product for infants with the addition of active substances from cyanobacteria, microalgae, or plants. In the theoretical part, a review was made, which not only summarizes the basic information about these organisms, but also the antioxidants contained in these microorganisms. In the practical part, several types of extracts from cyanobacteria, algae and plants were prepared and characterized. The content of phenolic substances, chlorophylls and content of carotenoids were measured spectrophotometrically. Content of soluble proteins was determined by Hartree-Lowry method and the fatty acid profile in biomass was obtained by GC. Furthermore, the SPF factor was measured using the spectrophotometric method the Mansur equation. Antioxidant activity was determined by using the TEAC method. Finally, two of the best extracts were selected for the preparation of cosmetic emulsions. The sensory analysis of prepared emulsions was performed for the period of two weeks.

Uses of active compounds from honey in cosmetic products
Balášová, Patricie ; Langová, Denisa (referee) ; Skoumalová, Petra (advisor)
The bachelor thesis was focused on the preparation and characterization of extracts and liposomes with active substances from chosen types of honey with the aim to apply these extracts to the cosmetic products. The extraction of active substances from chosen material was optimized during the work. As the most suitable organic solvent for extraction was chosen diethyl ether. All the extracts were tested on the content of total polyphenols, sugars and antioxidation activity. The final samples were also tested on the content of flavonoids. Extracts were encapsulated to the liposomes, which were tested especially for their antioxidation activity, size and stability. Then, extracts and liposome particles were applied to the cosmetic products. Cosmetic creams and gels were prepared and tested for antioxidation activity and antimicrobial activity against the strains Serattia marcescens and Micrococcus luteus. Antimicrobial activity of gels was proved especially against the strain of grampositive bacterias – Micrococcus luteus. From this point of view another one testing strain was chosen – Propionibacterium acnes. Finally, the chosen liposomes were tested for their contact with human cells, immortalized keratinocytes HaCat. No cytotoxic effect was observed and tested materials can be applied to cosmetics against acne.

Assessment of chosen aroma compounds in foods and cosmetics
Obrdlíková, Blanka ; Hrstka, Miroslav (referee) ; Vítová, Eva (advisor)
This diploma thesis is focused on the problematic of assessment of allergenic aroma compounds in various matrices. In the frame of European legislation 26 of potentially allergenic compounds are stated, whose content in cosmetic products is limited. In the case of foods there is not such restriction so far. In the experimental part, the allergenic aroma compounds in chosen samples of cosmetic and food samples were identified and quantified using Solid phase microextraction in conjunction with gas chromatography. Sensory evaluation of aroma or taste is also included.

Possibilities of using of Vitis vinifera as a source of raw materials for cosmetic production
Hanáková, Pavlína ; Vítová, Eva (referee) ; Zemanová, Jana (advisor)
This bachelor thesis deals with preparation of extraction from various parts of grapevine and their consequent use in the manufacture of cosmetics. The theoretical part is focused on general characteristics of grapevine, its taxonomic classification, occurrence and cultivation. Subsequently, the chemical composition of grapevine parts and their uses in cosmetic, food and pharmaceutical industries is described. The final part is devoted to particular types of extractions and methods of determinativ of total phenolic substances. The experimental part deals with the optimization of the prepared extract in order to obtain the extract with the highest amount of total phenolic substances with respect to production costs. Factors such as selection of the appropriate solvent and extraction time are examined. 50% ethanol at the room temperature was found to be an optimal solvent. Finally, the physical and chemical properties, such as density, pH and refractive index were determined for the purpose of producing a material safety data sheet. The extract was processed into cosmetic products.

Renovation of the railway station in Ústí nad Orlicí
Velešíková, Karolína ; Svoboda, Lukáš (referee) ; Májek, Jan (advisor) ; Daněk, Lukáš (advisor)
The subject of the Bachelor Thesis was the reconstruction of the railway station in Ústí nad Orlicí. The content of the thesis was the Documentation for Building Permits and Documentation for Building Construction, based on the architectural study, which was created in the subject AG34-Atelier of Architectural Design in the winter semester. The building is situated on the outskirts of the town of Ústí nad Orlicí, near the village Kerhatice. Tichá Orlice flows nearby, and on the northern side of the building the terrain rises into a wooded hill. The station was built in 1874. Because of spatial reasons the building was placed between two groups of tracks. At the moment the only access to the building is by underpasses or by access roads for firemen from Nádražní street. Because of the construction of the new railway station, underpasses to platforms and their repairs, the old railway station was decommissioned, but the building was saved and declared as a cultural monument. The main idea was to design an appropriate solution for the using of the old building and preserve its original appearance from the time of construction in 1874. Restore the restaurant in a single-storey building. Create residential areas for the building manager, provide temporary accommodation for travelers, locate interesting historical information about the building and linking the building to the educational trail, possible multifunctional spaces such as workshops, offices and a small shop. Also rental spaces for hairdressers and cosmetics are also available. The assignment was also a space solution next to the object that is not being maintained. Therefore, a park layout was designed which serves passengers as a relaxation zone, for children for fun. The layout is an abstraction of the sound curve of a going train.

CITES plants in cosmetic products
JAKUBCOVÁ, Claudia
This thesis deals with the properties of endangered plant species listed in CITES Appendices that are contained in cosmetic products on the Czech market and the characteristics of these products. The attitude and responsibility of companies towards environmental protection issues and the evaluation of these cosmetic products by users were investigated by questionnaires. A total of 20 species were found in 90 cosmetic products, of which 12 representatives were from the family of Orchideaceae, two species of cacti (Selenicereus grandiflorus, Opuntia ficus-indica), ginseng (Panax ginseng, Araliacae), Aloe ferox (Asphodelaceae), Euphorbia antisyphilitica (Euphorbiaceae), Aniba rosodora (Lauraceae), Aquilaria malaccensis (Thymelleaceae), Cyathea medullaris (Cyatheaceae). No cases of collection in the wild were found. All the evidence shows that the plants used in cosmetics are cultivated and therefore the CITES Convention is not violated. Users were satisfied with the cosmetic products.
