Summary: In this study, molecular characterization of sulfur compounds in a whole crude oil was conducted using gas chromatography and mass spectrometry techniques. The crude oil was separated into different fractions and different sulfur compounds were identified and characterized. The study found that the type and content of sulfur compounds vary significantly among the different distillation fractions.

Summary: A series of novel carotenoid-derived non-thiadiamondoids cage organic sulfur compounds (OSCs) were identified from crude oil. Non-polar sulfur compounds were isolated using the methylation/demethylation method and characterized using FT-ICR MS and GC-MS. The cage OSCs were tentatively identified as 2-thiatricyclo[4.4.0.0<3.8>]decanes. These novel OSCs were found to be generated by biological sulfate reduction, providing new clues for the preservation of hydrocarbons in geological environments through sulfurization. The cage OSCs have the potential to be biomarkers for studying sedimentary environments.

Summary: The study reveals the potential of exploiting A. trifoliata as an edible oil crop, and establishes a model for determining the oil content and composition of A. trifoliata seeds. Unsaturated fatty acids are the main component of ASO, and the PLS model based on GC-MS and near-infrared spectroscopy is effective for determining ASO and UFA content.
