Ocimum basilicum L. (Lamiaceae) is a spice plant frequently cultivated in Romania with application in food flavoring and preservation, pharmaceutical products and alternative medicine. The purpose of this study was to determine the chemical composition and antioxidant effectiveness of the essential oil of Ocimum basilicum grown in Romania. The basil inflorescences (fresh plant material) was used for the extraction of essential oil. The essential oil was isolated with a yield of 0.52% (v/m) by steam distillation. G...

This study aimed to investigate: i) the chemical composition and ii) the antimicrobial properties of the essential oil isolated from Lavandula angustifolia ?Sevtopolis? cultivated in western Romania. The essential oil, obtained by steam distillation, was evaluated by GC/MS. The inhibitory effects of Lavandula angustifolia ?Sevtopolis? essential oil were tested using the Kirby-Bauer agar disc diffusion method against five common food-related bacteria: Staphylococcus aureus (ATCC 25923), Pseudomonas aeruginosa (ATCC...

Industry, pollute environments (air, water, soil), and bring damage to the health, both to the people and all living beings. In areas where oil and gas development is prevalent, air, water and soil resources can become contaminated with oil and gas wastes and by products. The pollutants emitted by the oil and gas industry, may bring damage immediate or long-term, to the environment. Mining industry and the oil processing, affects the environment through gaseous and liquid hydrocarbons. All products resulting from ...

The article presents the results of humic acid macromolecule study based on the instrumental approaches. Humic acids were extracted from various types of peat (0-20 cm) found within the Western Siberia. The obtained results provide insight into the structure and composition of peat humic acids. The obtained results definitely indicate that elemental composition, thermodynamic stability, and NMR13? spectrometry of humic acids are basically a consequence of their physico-chemical properties which, in its turn, depen...
