The purpose of this study is to highlight the flavour compounds found in tonic beverages obtained from plants with bioactive potential. Identifying these compounds through GC-FID (gas-chromatographic coupled with flame ionization detector) modern methods are leading to the appreciation of these beverages and the possibility of improving the proposed recipes. Six drinks rated B1, B2, B3, B4, B5, B6 made from indigenous plants; the plants were dried at 65 ° C, macerated in 50% vol. ethanol for three days in a ratio ...

The purpose of this work was to study specific features of the accumulation and distribution of the total content and mobile forms of heavy metals (HM) in soils and plants of the estuarine ecosystems of the Don river and the Taganrog bay coast (Russian Federation). The soil cover is represented by following soils types: Fluvisols, Haplic Chernozem, Arenosol, Solonchak. The following higher plants were sampled: Phragmites australis Cav., Typha angustifolia L., Carex riparia Curtis, Cichorium intybus L., Bolboschoen...

Climate change and population growth are the key drivers of land use-land cover (LULC) change in sub-saharan Africa. Ecosystem services from the species biodiversity have been the sources of food and energy in Nigeria through agriculture and provision of food, firewood, and shelter. The change in LULC has led to the degradation of the natural resources especially the plants which their severe extinction poses major threats to the increasing rural population whose livelihoods depend on them. The study aimed at usin...

Trace elements (TE: Cu, Zn, Cd, Pb, Fe, Mn, Ni, Co, Ba, Zr, Sc) content in the components of the lake Kultuban (South Urals) and lake?s catchment ecosystem was studied. Trace element content was measured in samples of lake water, bottom sediments, shoots of reed Phragmites australis (Cav.) Trin. ex Steud., muscles of several fish species (Esox lucius, Carassius gibelio, Perca fluviatilis), samples of topsoil on catchment, above-ground phytomass, shoots of terrestrial plants Artemisia austriaca Jack., Thymus marsch...

This article is devoted to the assessment of toxic effect of benzo[a]pyrene (BaP) on spring barley (Hordeum sativum distichum) grown in background control Haplic chernozem and that spiked with various doses of BaP (20, 200, 400 and 800 ?g/kg) equivalent to 1, 10, 20 and 40 levels of maximal permissible concentrations (MPC). The experimental soil samples were planted every spring and incubated outdoor during 4 years. During the experimental time (almost 4 years), concentrations of BaP decreased by 80-87% in the soi...
