Variabilita obsahu a složení silic u vybraných druhů koření (Ocimum basillicum L., Satureja hortensis L. a Majorana hortensis Moench.)
Benešová, Jana
The thesis Variability and composition of essential oil content of selected spices (Oci-mum basillicum L., Satureja hortensis L. and Majorana hortensis Moench.) Deals with plant species of whose main ingredient is oil. There is described a process for the isola-tion of essential oils from plants, individual components of essential oils, their variability and ways of using. Selected representatives of the so called green spices belong to the mint family (Lamiaceae), whose typical feature is very high content of essential oils. In the practical part were evaluated following species: basil (Ocimum basilicum), sum-mer savory (Satureja hortensis L.) and marjoram (Origanum majorana syn. Majorana hortensis). Essential oil content was determined in each type, by steam distillation and then the composition of essential oils was found by gas chromatography.

Obsah silic ve vybraných druzích léčivých, aromatických a kořeninových rostlin, které se používají i jako „zelené koření“
Kyselová, Martina
Ethereal oils are described in this bachelor's work. There is a characterization of ethereal oils, of its occurrence, properties and way of isolation these plants. The best-known types of these plants, which are called "green spice", are eleborated in this work. It also contains experimental determination of content by choosen samples, which were acquire from two sources - LEROS s.r.o company and from Žabčice, MENDELU in Brno. Ethereal oils were insulated by a method of destilation with water vapour. Acquired plenty of e.oils was compared with a norm's requirements, eventually with a czech formulary.

Production and alleopathic potential of plants of Satureja genus
HOŘEJŠÍ, Lenka
In Czech Republic, two species of savory namely summer savory (Satureja hortensis L.) and winter savory (Satureja montana L.) are grown. Aim of this work is to summarize information about biological characteristics and requirements of both species on environmental conditions, production of these drugs in the Czech Republic and abroad, effective substances and their effects and possibilities of savory utilization in manufacturing industry and agriculture. Overground parts and leaves of savory plants are exploited like a spice or a drug that positively influences digestion, reduces flatulence and has also anti?inflammatory effects. Major components of volatile oil savory are phenolic compounds carvacrol and thymol. Just carvacrol and thymol are considered as allelopathic compounds of mint, sweet basil, caraway and others. On the basis some studies, we can assume that they are also potential allelopathic compounds of savory. Summer savory is more suitable for growing in the Czech Republic especially in the ecological agriculture than winter savory. We can easily include this crop in the crop rotation because it is an annual plant and there is a lower hazard of failure e.g. frost damage. Growing of winter savory would be more suitable for the essential oil production.
