Petroleum is the most common global fossil fuel. It a complex multi-component system mainly composed of various hydrocarbons such as alkanes, cycloalkanes, mono-, bi- and polyaromatic compounds, resins asphaltenes. In spite humanity’s need for petroleum, it negatively affects environment due to its toxicity. The ecological problem especially serious at petroleum mining sites or during transport...

Introduction: Bioremediation has been shown to be an effective strategy for removing toxic pollutants from the environment, particularly organic chemicals such as petroleum hydrocarbons. This paper investigates changes in toxicity of petroleum-contaminated soil a result microbial remediation processes. Methods: Changes ecotoxicity contaminated were examined using plant, earthworm, enzyme activi...

OBJECTIVES The objective of present study was to evaluate the effect of active principle (Cg-1) from Cassia glauca leaf on serum glucose and lipid profile in normal and diabetic rats. MATERIALS AND METHODS Diabetes was induced by streptozotocin in neonates. Oral administration of petroleum ether, chloroform, acetone, and methanol of C. glauca leaf (100 mg/kg, p.o.) for 21 days caused a decrea...

Diamondoids in crude oil are useful for assessing the maturity of oil in high maturation. However, they are very difficult to separate and accurately quantify by conventional geochemical methods due to their low abundance in oil. In this paper, we use comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC×GC-TOFMS) to study the compounds in condensates from t...
