一种不寻常的C27-三萜烷是挪威大陆架侏罗纪页岩的主要饱和烃。基于气相色谱-质谱和质子核磁共振数据，提出了初步结构：25，28，30-三去甲环烷烃。这是首次从地质样品中发现C-10位脱甲基的三萜烷。与公布的质谱信息的比较提供了证据，这种核降解三萜烷也是侏罗纪北海石油源岩和相关原油的烷烃馏分的主要成分。
An unusual C27-triterpane is the major saturated hydrocarbon of a Jurassic shale from the Norwegian Continental Shelf. Based on gas chromatography—mass spectrometry and proton magnetic resonance data, a tentative structure,25,28,30-trisnormoretane, is suggested. This is the first report of a triterpane demethylated at C-10from a geological sample. Comparison with published mass spectral information provides evidence that this nuclear degraded triterpane is also a major constituent of the alkane fractions of Jurassic North Sea petroleum source rocks and related crude oils.
