Eight major chemicals are identified after analyzing the essential oil of the seeds of three medicinal plants Punica granatum, Vitis vinifera and Cucurbita maxima, using Gas Chromatography/Mass Spectrometry (GC-MS). Only three of the identified chemicals (Farnesene, Docosane and Tetracosane) were found in all three samples, but in varying proportions. Trans-Squalene was found in Cucurbita maxim...

The present study was conducted to examine various biological activities of a methanol extract of Agave attenuata leaves. GC-MS analysis of the n-hexane fraction from the extract revealed the presence of 31 compounds, with mono-2-ethylhexyl phthalate (11.37%), 1,2-benzenedicarboxylic acid (6.33%), n-docosane (6.30%) and eicosane (6.02%) as the major components. The leaves contained appreciable ...

Abstract The technical importance of paraffins as phase change materials (PCM) in heat storage systems increases. Knowledge on the thermal conductivity is necessary for design and optimization systems. However, most solely liquid state has been sufficiently investigated. For solid state, precise data are only known a few paraffins, while generalized values available remainder, some which contra...

PURPOSE Marrubium crassidens, a plant belonging to the family Lamiaceae, was studied for its volatile components present in the aerial parts of the plant during the flowering stage. METHODS The essential oil of the plant obtained through hydrodistillation of the dried plant material was assessed for its chemical composition by GC/MS and GC-FID analyses. RESULTS Twenty-five compounds were id...

The reaction of [Ni(L)]Cl(2)·2H(2)O (L = 3,14-dimethyl-2,6,13,17-tetraazatricyclo [14,4,0(1.18),0(7.12)]docosane) with trans-1,2-cyclopentanedicarboxylic acid (H(2)-cpdc) yields a 1D hydrogen-bonded infinite chain with formula [Ni(L)(H-cpdc(-))(2)] (1). This complex has been characterized by X-ray crystallography, spectroscopy and cyclic voltammetry. The crystal structure of 1 exhibits a distor...
