Hydrodistilled leaves of Chenopodiumalbum yielded 0.64 % v/w of essential oil. GC and GC/MS analyses of the oil revealed that the bulk of the oil was constituted by aromatic compounds (60.1 %). The abundant constituents of the oil were: p- cymene (40.9 %), ascaridole (15.5 %), pinane-2-ol (9.9 %), α-pinene (7.0 %), β-pinene (6.2 %) and α-terpineol (6.2 %). The oil displayed strong anti-inflamma...

The first example of a transition-metal-catalyzed, meta-selective C-H bromination procedure is reported. In the presence of catalytic [{Ru(p-cymene)Cl2 }2 ], tetrabutylammonium tribromide can be used to functionalize the meta C-H bond of 2-phenylpyridine derivatives, thus affording difficult to access products which are highly predisposed to further derivatization. We demonstrate this utility w...

The asymmetric unit of the title compound, [RuCl(C(10)H(14))(C(17)H(19)O(2))], contains two diastereomers. In both, the Ru(II) ion has a tetra-hedral coordination, formed by two O atoms of the camphor-derived ligand and the p-cymene and Cl ligands. In the crystal structure, weak inter-molecular C-H⋯Cl inter-actions link the mol-ecules into columns propagated along [010].

Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. (Xoo) is one of the most damaging diseases to rice across world. Various chemicals have been employed so far for management bacterial blight. On other hand, these compounds are ecosystem and an impact on non-target species such as humans animals. As a result, there need create new natural inhibitor BLB management. Deformylase (PDF) en...

Abstract A terpene‐based biorefinery is described that uses crude sulfate turpentine (CST) and gum (GT) to produce mixtures of p ‐menthadienes ( ‐MeDs) as biorenewable terpene feedstocks. An acid catalyzed ring opening reaction (6 m aq. H 2 SO 4 , 90 °C) first used convert the major bicyclic monoterpenes (α‐pinene, β‐pinene, 3‐carene) in untreated CST (or GT with 5 mol% Me S) into monocyclic ‐M...

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...

background and objectives : the aim of this study was to evaluate the chemical composition and antimicrobial activity of satureja hortensis and trachyspermum copticum essential oils against different kinds of microorganisms in vitro. material and methods : the antimicrobial activity was evaluated by micro broth dilution assay and analysis of essential oils chemical composition by gc and gc/ms a...
