Several oleanane-related triterpenoids bearing a unique C-2 oxygenated functionality have been identified as the predominant triterpenoids from a 4900 year old oak wood sample buried in a freshwater sediment. They likely represent specific molecular tools that can be used as markers to reconstruct past vegetation assemblages, or to recognise severely altered oak wood at archaeological sites.
