摘要：
An alkane fraction isolated from Pakistani oil seep samples using liquid chromatography on US-Y molecular sieves has been shown to contain six pseudohomologous series of tetracyclic compounds that have mass spectral characteristics of 8,14-secohopanes with carbon numbers extending to 35. This is the first report of extended 8,14-secohopanes in a crude oil, although extended 8,14-secohopanes with up to 32 carbon atoms have previously been reported from a Chinese coal of Jurassic age. The Kovats indices of these extended 8,14-secohopanes are reported from measurements using capillary gas chromatography columns with nonpolar and polar stationary phases.
