Cosmetics preparations against acne
Měšťánková, Zuzana ; Skoumalová, Petra (referee) ; Němcová, Andrea (advisor)
Hemp is a plant containing a number of active substances that can be used in cosmetics and pharmacy. The subject of this bachelor thesis is the multiplication of active substances by mixing cannabis with herbs that have anti-inflammatory effects. The theoretical part contains a description of the determined antioxidants and cannabinoids. The experimental part focuses on measuring the content of these substances in extracts created from the dry parts of herbs and hemp variety Ferimon. The work is also focused on the preparation of a cream containing cannabis and herbal extracts, which are aimed at inhibiting the formation of acne. The antimicrobial effect of creams and extracts was investigated on bacteria Propionibacterium acnes and Micrococcus luteus. The analysis of the extracts shows that the largest amount of active substances contained a mixture of mountain arnica and hemp, which also showed a good antimicrobial effect against both types of bacteria. The creams showed a low inhibitory effect due to the low content of active substances.

Hemp belongs among important plants with therapeutic effects thanks to its high content of substances. This bachelor thesis brings information about the use of hemp in acne preparations. The theoretical part of this thesis focuses on the characterization of hemp and its active substances. The next chapters deal with acne and Propionibacterium acnes, which is involved in the course. For the experimental part, the extracts of two hemp varieties (Ferimon and Carmagnola) were characterized in terms of antioxidant and cannabinoid presence. The cosmetic preparations with hemp extract content were prepared and commercial products were purchased too. In both the extracts and the cosmetic preparations, their inhibitory effect against Propionibacterium acnes was observed. Micrococcus luteus, Candida glabrata and Escherichia coli were also tested. The results show that dried hemp flower extracts contain the largest amount of active substances. All hemp extracts had effect against gram-positive bacteria, in cosmetic preparations it was minimal effect or no effect.
Food and cosmetic use of technical hemp
Puškárová, Radka ; Skoumalová, Petra (referee) ; Němcová, Andrea (advisor)
The thesis occupies with the use of hemp in cosmetics and in food processing. In the theoretical part hemp was characterized by the content of active substances. In the experimental part the thesis is concerned with characterization of two different hemp varieties Carmagnola and Ferimon in terms of presence of active substances. The next part focuses on preparation of cosmetic with hemp content. In cosmetic preparations and in the extracts the inhibitory effect against Propionibacterium acnes, Micrococcus luteus, Escherichia coli and Candida glabrata was tested. The content of fatty acids and vitamin E was determined in hemp seed. The results show that dried hemp flower extract contains the largest amount of active substances and has the greatest inhibitory effect against all tested bacteria except Candida there was no effect. Cosmetic preparations did not show almost any inhibitory effect because of low concentration of active substances. The hemp seed contained high amount of PUFA and essential fatty acids. Vitamin E was found out in all of three hemp oils.

Study of hygrotherma behavior of thermal insulating materials based on natural fibers
Kosturová, Andrea ; Peterková, Jitka (referee) ; Zach, Jiří (advisor)
The content of this work is to describe the transport of heat and moisture in thermal insulation materials based on natural fibers. The disadvantage in using these materials when incorporated into the construction is their low resistance to moisture. Therefore this work is further interested on possible modifications of natural fibers, which could correct it. Implemented literature research is approaching trends in the usage of dynamic simulations of heat and moisture transfer through material. Based on the findings from previous works on the VUT and theoretical part there were applied various kinds of impregnating preparations on a sample of insulation from hemp and the evaluation of their effect on the properties of the insulator.
Testování tolerance vybraných genotypů konopí vůči fytotoxickým účinkům zinku
Kabina, Viktoriia
This bachelor thesis was aimed at testing the tolerance of selected hemp genotypes to the phytotoxic effects of zinc. In the theoretical part, the main aspects of the toxic effect of heavy metals on plants were analyzed. Here the sources of environmental contamination with heavy metals, the uptake of heavy metals by plants, the effects of heavy metals on plants and their tolerance mechanisms are described, and the phenomenon of phytoremediation as a method of soil purification is also described. In the practical part, the influence of different zinc concentrations on selected hemp genotypes, namely French variety Felina 32 and Hungarian variety Monoica, were studied. The growth parameters of the experimental plants and the pigment content in the leaves of the plants were determined. The experiments did not prove serious effects of zinc on experimental plants, except for high concentrations in individual cases. Nevertheless, it can be said that in comparison with the Monoica variety, representatives of the Felina 32 variety were more sensitive to the presence of zinc in the soil.
