摘要：
Several polycyclic aromatic hydrocarbons (PAH) have been identified in recent Amazon River and Cariaco Trench sediments. The skeletal structures of these compounds suggest triterpenoid precursors. The tetracyclic compounds seem to result from A-ring cleavage and the pentacyclic compounds from aromatization which begins with ring A and proceeds through ring D. These compounds are another example of the environmental occurrence of natural PAH. © 1979.
