Identification of Bicyclic Sesquiterpanes in Oils from the Niger Delta, Nigeria
O.O. Sonibare and C.M. Ekweozor

Abstract:
Two series of bicyclic sesquiterpanes have been identified in the crude oil from the Niger delta by Gas chromatography-Mass spectrometry. The mass spectra of the sesquiterpanes were compared with those of previously reported compounds. The first series with base peak at m/z 193 or 123 had mass spectra that corresponded with C15H28 (M+: 208) and C16H30 (M+: 222). The second series was distinguished by base peak, m/z 123 and corresponded to C21H40 (M+: 292), that is bicyclic terpanes having branched chain. The presence of these compounds in the Niger delta oil suggests a significant terrigenous input into the source-rock of the oils.
