Novotná, Petra ; Vespalcová, Milena (referee) ; Zemanová, Jana (advisor)
The aim of this bachelor’s thesis is an investigation of use of less traditional plant sources in cosmetic industry. This review is focused on black elder (Sambucus nigra), sea buckthorn (Hippophae rhamnoides), quince (Cydonia oblonga), dog rose (Rosa canina), and stinging nettle (Urtica dioica). The substances Isolated from these plants can be used in various cosmetic products. The first section of this search deals with history and botanical characterization of these plants. The next section deals with significant substances contained in these plants and their use not only in cosmetic industry.
Biologically active phenolic compounds in small fruit.
LAXOVÁ, Lenka
This master´s thesis focuses at bioactive compounds in edible berries during its culinary processing. Elderberries (Sambucus nigra L.) were selected as a representative of edible berries variety. Elderberry is known for presence of significant bioactive compound content and usage in traditional medicine. Elderberries were processed acording to common culinary recipes. Amount od selected bioactive polyphenolic compounds (chlorogenic acid, quercetin, rutin, anthocyanes) was detected accordingly. Additionally content of ascorbic acid was determined. On the basis of the experimental determination, it was found that anthocyanes and rutin are the most common compounds found in elderberries. All analytes in juices and sirups gradually decreased during the treatments and long-term storage. On the contrary, the content of quercetin increased with gradual modifications and storage. The highest decrease was observed for vitamin C content. The lowest values in the products from elderberries were reached by quercetin and ascorbic acid.
