摘要：

Bicadinanes (C30 pentacyclic triterpanes) have only been reported in crude oils and sediment extracts from S.E. Asia. The present investigation indicates that they are also widely present in land plant-derived Tertiary oils from the Surma Basin of N.E. Bangladesh. Oleanane is also abundant in these oils though its distribution does not correlate with those of the bicadinanes. This is consistent with separate specific land plant sources for these two classes of triterpanes, and with the formation of bicadinanes during maturation of polymerised angiosperm tree resin. © 1990.
