Lethal concentrations of 50% (LC50) 24 and 48h after EO exposure were found to be 3.69 and 2.19 when solubilized in ethanol and 9.14 and 6.05 μL/cm2 when solubilized in acetone, respectively. The major compounds were germacrene B, δ-cadinene, γ-elemene, (Z)-cariophyllene, α-copaene...
The purpose of the exercise is to understand how radial variations in composition and temperature are influenced by the presence of a cooling jacket, which may be used to control the performance of a tubular reactor. The exercise also shows how the properties of the reactions and the reactor ...
The results showed that among all hawthorn extracts, methanol and ethanol extracts (ME and EE) exhibited high levels of total flavonoids and polyphenols contents, followed by acetone, ethyl acetate, trichloromethane and petroleum ether extracts. ME exhibited the strongest antibacterial activity against ...
The obtained GC/MS data were used to identify the particular compounds and characterize the chemical composition of the EVOOs samples. In addition a chemometric pattern recognition technique was used for multivariate data analysis. The variations in the GC/MS fingerprint of the different samples were...

The BiNP@LIG nanocomposite was successfully synthesized by laser irradiation (470 nm), and the composition of the obtained material was further verified by X-ray diffraction, energy dispersive spectroscopy and Raman spectroscopy. Moreover, the morphology of the BiNP@LIG nanocomposite was investigated ...
In the summer samples, the oils of C. bonariensis were rich in matricaria ester (1.6-76.4%), caryophyllene oxide (1.6-22.6%) and (E)--farnesene (1.1-22.7%). The main constituents in the autumn samples were matricaria ester (trace to 63.5%), geranyl acetone (0.0-25.3%), trans-±-...
maritima subsp. bicolor was characterised by the presence of hexadecanoic acid (14.6%), caryophyllene oxide (9.3%) and hexahydrofarnesylacetone (6.5%). The comparison of the essential oil with other studied oils of the genus Jacobaea is discussed.Antonella Maggio...
Caryophyllene (50.6%), caryophyllene oxide (29.84%), farnesyl acetone (4.65%) represented the major components of the tubers EO. While D-limonene (63.78%), theaspirane A (13.36%), theaspirane B (10.97%) and γ-terpinene (3.4%) were the majors of aerial parts EO. The aerial parts ...
The purpose of this study was to investigate the chemical composition and biological activity of the volatile oils (VOs) from the flowers of three buckwheat species, Fagopyrum esculentum, Fagopyrum tataricum and Fagopyrum cymosum. The VOs were obtained from the fresh buckwheat flowers by hydrodistillati...
