Three tetracyclic acids were identified in a Nigerian crude oil, after reduction and deuterium labelling followed by GC/MS investigation. Two of them are identical to 3:4 seco acids previously identified in sediments. The third one is a novel C 24 acid that has not been reported up to now. These geochemical markers are assumed to belong to the class of photochemical tetracyclic triterpenes formed by decay of pentacyclic 3-ketoterpenoids.
