Biomass Yield, Essential Oil Yield and Oil Quality of Rose-scented Geranium (Pelargonium graveolens L.), Intercropped with Vegetables

To improve essential oil quality, especially to reserve the thermal instability of compounds, supercritical CO2 extraction (SFE) was applied to recover essential oil from Cymbopogon citronella leaves. A response surface methodology was applied to optimize the extraction process. The highest essential oil yield was predicted at extraction time 120 min, extraction pressure 25 MPa, extraction temperature 35°C, and CO2 flow 18 L/h for the SFE processing. Under these experimental conditions, the mean essential oil yield is 4.40%. In addition, the chemical compositions of SFE were compared with those obtained by hydrodistillation extraction (HD). There were 41 compounds obtained of SFE, while 35 compounds of HD. Alcohols and aldehydes were the main compositions in the essential oils. Furthermore, the antioxidant activities and antimicrobial of essential oils obtained by HD and the evaluated condition of SFE were compared. Results showed that the antioxidant activities of SFE oil are better than those of HD. Minimum inhibitory concentrations (MICs) were determined by the microdilution method. Essential oil obtained from SFE and HD exhibited a significant antimicrobial activity against all tested microorganisms. It is confirmed that the SFE method can be an alternative processing method to extract essential oils from Cymbopogon citronella leaves.

Essential Oil Yield

The work deals with the possibility of improvement of qualitative and quantitative parameters of caraway (Carum carvi L.). The yield of the achenes is not satisfactory during last years and qualitative demands are clarify in correspondence to the market. The possibilities of this variation can be found in growing technology and in variety spectrum. The influence of weather is inconsiderable. Therefore, the experiments with three varieties were found (PROCHAN, KEPRON and REKORD). They were cultivated in cover crop and as pure growth on three sites. The yield components were evaluated in all variants: the yield of the achenes from m2, HTS (the weight of thousand seeds in g), the essential oil content in % and essential oil yield in kg.ha–1. On the basis of the results from the experiments we can make following conclusions. The highest yield was recorded in Šumperk site with cover crop. The varieties did not affect the yield. HTS was different on the sites, the highest HTS had the achenes from Telč. The differences were determined between vegetative periods. Also the essential oil content, similarly as the HTS, was influenced by the vegetative period and by the site. The essential oil yield corresponded with the essential oil content and with the yield of the achenes. The vegetative period almost always affected yield and the quality of caraway fundamentally. There were no differences among the varieties for all studied traits.
