satureja sahendica bornm. is an endemic medicinal plant which grows wild in natural habitats of west and north-west regions of iran. in this study, for domestication of satureja sahendica and study it's essential oil content and composition, the seeds of seven populations were collected from natural habitats and cultivated in three replications as a complete randomized blocks design. the a...
A theoretical study using semi-empirical (PM3) and DFT calculations (B97D) was performed in both gas and aqueous phases, in order to obtain structural and energetic properties for the encapsulation process of p-Cymene into -cyclodextrin. Two modes of inclusion were assumed for the [p-Cym...-CD] host-guest complex: (i) Mode A, when the guest is placed in the hydrophobic cavity of the CD by the...
Abstract The protic ionic liquid pyridine hydrochloride is known to be a non-aqueous solvent for metal oxides, including rare-earth oxides. However, its application in extractive metallurgy and especially extraction has been so far limited by miscibility with the aqueous phase. In this paper, molten (165 °C) was used dissolve production scrap of Nd–Fe–B permanent magnets recover valuable metals...
Studies involving the consumption,metabolism, and elimination of terpenes by small ruminants consuming terpene-laden shrubs as well as those exploring the potential for natural products as rumen modifiers could benefit from a procedure that measures terpenes in both blood and rumen fluid and that is suitable for either serum or plasma. The objective of this study was to modify an existing proce...
The composition of the essential oils hydrodistilled from the aerial parts of five Achillea biebersteinii Afan samples, collected in central Turkey from Konya, Isparta and Ankara, were analyzed both by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Eighty-four components were identified, representing 87 to 99% of the total oil composition. The identified major com...
We report an evaluation of the cytotoxicity of a series of electron-deficient (16-electron) half-sandwich precious metal complexes of ruthenium, osmium and iridium ([Os/Ru(η6-p-cymene)(1,2-dicarba-closo-dodecarborane-1,2-dithiolato)] (1/2), [Ir(η5-pentamethylcyclopentadiene)(1,2-dicarba-closo-dodecarborane-1,2-dithiolato)] (3), [Os/Ru(η6-p-cymene)(benzene-1,2-dithiolato)] (4/5) and [Ir(η5-penta...
Ruthenium compounds have become promising alternatives to platinum drugs by displaying specific activities against different cancers and favourable toxicity and clearance properties. Nonetheless, their molecular targeting and mechanism of action are poorly understood. Here we study two prototypical ruthenium-arene agents-the cytotoxic antiprimary tumour compound [(η(6)-p-cymene)Ru(ethylene-diam...
