Variabilita obsahu a složení silic levandule lékařské z různých proveniencí
Fojtíková, Lucie
The aim of this work was the determination of variability of the essential oil content in lavender obtained from different sources. The results indicate that significant differences were found both in the essential oil content and in its composition. Only the samples of the Lavandula angustifolia P. MILL (L. officinalis CHAIX) were used to obtain the essential oils. According to the Czech Pharmacopoeia 2014, the drug (lavender flowers) should contain at least 1.3 ml of essential oil in 100 g of anhydrous drug and lavender essential oil should contain following ingredients: limonene < 1.0%, cineol < 2.5% (eucalyptol), 3-octanone < 2.5%, camphor < 1.2%, linalol 20.0% to 45.0%, linalylacetate 25.0% to 46.0%, terpinene-4-ol 1.2% to 6.0%, lavandulylacetate > 1.0%, lavandulol > 0.1%, α-terpineol < 2.0%. In addition, five microbial lavender samples of different provenances were determined by microbiological purity of the drug, whereby the amount of colonies per 1 ml was determined for the total number of microorganisms, spore microorganisms, enterobacteria, yeasts and fungi.

Vašíčková, Milada ; Vysoká, Marie (referee) ; Skoumalová, Petra (advisor)
The presented bachelor thesis is focued on active substances contained in lavandula officinalis and common thyme extracts, mainly their possible antimicrobial and antioxidant effects. The theoretical part desrcibes chosen plants, compounds with antimicrobial and antioxidant effects, methods how to obtain and identify said compounds. In the experimental part, aquenous, ethanolic and oil extracts were prepared. Mentioned extracts were spectrophotometrically characterised for total content of polyphenols, total content of flavonoids and antioxidant activity. In conclusion possible applications of extracts in food industry instead of synthetic preservatives and their fotification were discussed.

Bílková, Zuzana ; Martin, Jan (advisor) ; Tůmová, Lenka (referee)
Zuzana Bílková, Biological activities of Lavandula angustifolia essential oil, Thesis, Charles University in Prague, Faculty of Pharmacy in Hradec Králové, thesis author: PharmDr. Jan Martin, PhD., Hradec Králové, 2013, 72 pages. The thesis called "Biological activities of Lavandula angustifolia essential oil" is interested in biological activities of Lavandula angustifolia essential oil, specifically antifungal, antioxidant, anti-inflammatory, cytotoxicity, nematicidal and repellency activities. The aim of work was to find out, if the oil can be used in these indications and become natural substitution to the chemical compound toxic to the environment. Antifungal activity was tested against the most common human patogenes, low toxicity proves that essential oil can be used on human cells without causing any harm. Antioxidant activity was tested on NO reaction, nematicidal activity was tried on proctection of crop where nematodes cause huge economic loss. Repellency activity can protect both decorative and agricultural plants. Key words: Lavandula angustifolia, biological activities, anti-inflammatory, antifungal, cytotoxicity, repellency, antioxidant, nematicidal, essential oil.

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.
Analysis of essences in some plant materials
Koloničná, Markéta ; Svoboda, Zdeněk (referee) ; Mikulíková, Renata (advisor)
The peppermint (Mentha piperita) and the levander (Lavandula angustifolia) are the aromatic herbs with the healing and spices effects. Their essencial oils serve to production of the aromatic substances, they are used in the cosmetic and the food industry. In this thesis were analyzed substances which are contained in levander and peppermint oils. These oils were extracted through the destillation with the water steam, next they were analyzed by the gas chromatograph and the mass spectrometer. The aim of the thesis was found which substances contain these oils. In the levander oils were proofed the highest amounts of the cineole, linalool and the linalyl-acetate. In the peppermint oils were proofed the highest amounts of the menthon and the menthol.
