Isolation of Dihydro-β-sitosteryl Ferulate from Corngerm Oil.

New Dihydro-β-agarofuran Sesquiterpenes from Parnassia wightiana Wall: Isolation, Identification and Cytotoxicity against Cancer Cells

Five new (4-8) and three known (1-3) dihydro-β-agarofuran sesquiterpene polyesters were isolated from the whole plants of Parnassia wightiana. The structures of all compounds were elucidated through spectroscopic analysis including 2D-NMR and HR-MS. The absolute configuration of these compounds was established by X-ray diffraction analysis, comparison of NOESY spectra and biogenetic means. The ...

Isolation, Identification and Evaluation of Oil Hydrocarbon Decomposing Bacteria from Contaminated Areas of Oil Fields

Microbialbiodegradation is known as an effective and harmless method to overcome environmental pollution with oil hydrocarbon. Some bacterial species were isolated from the Sarvestan oilfields (Iran, Fars province), then identified and applied for oil hydrocarbon decomposition. A carbon-free minimum medium (CFMM) containing 1% crude oil was used to isolate bacteria through incubation at 30°C in...

Isolation of a Dibenzothiophene Desulfurizing Bacterium from Soil of Tabriz Oil Refinery

Isolation and Identification of Ginger Essential Oil

ABSTRACT: The essential oil of plant material is the fraction isolated by means of several methods such as liquid carbon dioxide, microwaves and low or high pressure distillation employing boiling water or hot steam and is chemically defined as terpenoids namely monoterpene and the oxygenated form. Since these compounds might be employed as flavour contributors due to their chemical nature, it ...

Isolation of Biosurfactant Producing Bacteria from Oil Reservoirs

Biosurfactants or surface-active compounds are produced by microoaganisms. These molecules reduce surface tension both aqueous solutions and hydrocarbon mixtures. In this study, isolation and identification of biosurfactant producing bacteria were assessed. The potential application of these bacteria in petroleum industry was investigated. Samples (crude oil) were collected from oil wells and 4...
