This study conducted a comparative analysis of extractable hopanoid hydrocarbons and those released via stepwise pyrolysis of typical Eocene immature oil shales in China,namely the Huadian,Maoming,and Fushun shales.Bo...
Applying dispersants to spilled crude oil results in an oil in water dispersion of microscopic oil droplets that soon dilutes to levels below 1 ppm oil. These levels are substantially below those known to induce acute...

Saturated fractions in a total of 23 oil samples and hydrocarbon source rocks from the Songliao, Tarim,and Ordos Basins have been analyzed by GC–MS and GC–MS–MS. According to the relative retention, mass spectral c...
An analytical method for quantifying biomarker compounds of the sterane and the hopane existing in saturated hydrocarbons has been established by using comprehensive two-dimensional gas chromatography-flame ionization...

A new hopane triterpenoid, hopane 22, 29-diol-29-formate (1), has been isolated from the whole herbs of Saxiglossum angustissimum (Cries.) Ching and its structure has been successfully determined on the basis of s...
: Four typical distribution patterns of pentacyclic triterpenoid hydrocarbons (types A-D) are distinguished in the low-mature source rocks from eastern China. Type A has a relatively high content of pentacyclic triter...
As triterpenoid biomarkers mainly derived from prokaryote (e.g. bacteria andcyanobacteria), hopenoid hydrocarbons are ubiquitous in fossil fuels and sediments.Ensminger et al. (1974) reported a normal distribution...
