background and objectives: datura innoxiamilleris one of the two species of datura (solanaceae) which grow in iran. there are many reports of the biological activities of datura and in the present study the ability of datura innoxia for inhibiting angiogenesis was evaluated. methods: the methanol extract and petroleum ether, chloroform and methanol fractions of datura innoxia flowers were obtai...

During the Deepwater Horizon disaster, a substantial fraction of the 600,000-900,000 tons of released petroleum liquid and natural gas became entrapped below the sea surface, but the quantity entrapped and the sequestration mechanisms have remained unclear. We modeled the buoyant jet of petroleum liquid droplets, gas bubbles, and entrained seawater, using 279 simulated chemical components, for ...

Biodiesel, an alkyl ester of plant oils that can be used in an unmodified diesel engine, is the first renewable diesel fuel alternative to become a commercially accepted part of our nation’s energy infrastructure. For traditional diesel fuel exhaust, it has been demonstrated that the particulate matter (PM) organic components play a role in acute inflammatory reactions. However, there have been...

artemisia is an important genus of iranian flora whose potent anti-proliferative effect has been demonstrated previously on human cancerous cell lines. in the current study, further fractionation was carried out on the petroleum ether extract of a. aucheri and their cytotoxic effects were evaluated on three human cancer cell lines. cell viability was determined by 3-(4,5-dimethylthiazol-2yl)-2,...

The title compound pteleifolosin C, C(21)H(20)O(7), was isolated from the petroleum ether-soluble fraction of an indigenous Chinese tree Melicope pteleifolia (Rutaceae). The dihedral angle between the benzene rings is 2.7 (2)°. Intra-molecular O-H⋯O hydrogen bonds occur. In the crystal, mol-ecules are linked by inter-molecular O-H-O hydrogen bonds.

Background & Aims: Teucrium polium (TP) is amongst the commonly used remedies in traditional medicine. Some reports have claimed hepatotoxicity of TP but other reports have not supported it. This study was designed to evaluate the probable hepatotoxicity of TP. Methods: Petroleum ether fraction of TP was dissolved in DMSO and the final concentration was adjusted by diluting in physiologic salin...

ABSTRACT Introduction: Medicinal plants belong to Lamiaceae family are potential sources of new drugs to improve the treatment of diseases which its treatment is linked to anti-oxidative agents. In this paper, antioxidant potentials of some Lamiaceae species have been evaluated by two methods. Methods: phosphomolybdate assay for total antioxidant capacity and ferric reducing a...

Heavy vacuum gas oil (HVGO) is a complex and viscous hydrocarbon stream that is produced as the bottom side product from the vacuum distillation units in petroleum refineries. HVGO is conventionally treated with thermochemical process, which is costly and environmentally polluting. Here, we investigate two petroleum biotechnology applications, namely valorization and bioupgrading, as green appr...
