Tritiated β‐amyrin (olean‐12‐en‐3β‐ol, 2 ) was synthesized in six steps, from epikatonic acid ( 3 ), with a specific activity of 550 GBq/mmole. The protracted incubation of this triterpene in a pond mud led by biodegradation to labelled aromatic tetracyclic hydrocarbons, identical with known sedimentary biomarkers.
