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.

Extrakce éterického oleje pomocí procesu okamžitého odpaření: aplikace na indonézské květy Ylang-Ylang
 Kristiawan, M. ; Sobolík, Václav ; Allaf, K.
The extraction of Indonesian ylang-ylang oil was carried out by new process: Instantaneous Controlled Pressure Drop (DIC). This process involves subjecting the dried ylang-ylang (Cananga odorata Hook. fil. et Thomson, forma macrophylla) flowers for a short period time to a saturated steam pressure, followed by an abrupt pressure drop into vacuum (about 50 mbar).

Extrakce silice z řebříčku superkritickým CO2
 Bocevska, M. ; Sovová, Helena
Flowers of yarrow were extracted with supercritical carbon dioxide using onestage sub-critical separation. The process was conducted to optimize conditions for obtaining essential oil free of waxes. The effectiveness of the process was compared with hydrodistillation. It was established that particle size has no influence on extraction yields.
