摘要：

An extended series of tricyclic terpanes was identified in sediments and petroleums from Brazil. The identification of the tricyclic terpanes was based on their chromatographic behavior and characteristic MS/MS transitions from molecular ions to m/z 191. We identified tricyclic terpane homologs up to C54. The presence of this extended series, from C19 up to C54, varies considerably with depositional environment, being prominent in saline lacustrine and marine carbonate settings. This suggests that the biological precursor organism lived in moderate conditions of salinity.
