  Characterisation of 24-nor-triterpenoids occurring in sediments and crude oils by comparison with synthesized standards

  摘要：

  A series of 24-nor-triterpenoids; 24-nor-urs-12-ene, 24-nor-olean-12-ene and 24-nor-lupane have been identified in sediments and crude oils by comparison with standards obtained by synthesis. A further suite of 24-nor-oleanenes has also been identified by comparison with the acid-catalysed rearrangement products of 24-nor-olean-12-ene. The presence of these components in sedimentary organic matter points to an important new pathway of terrigenous triterpenoid diagenesis.
