title: Aromatized C-2 oxygenated triterpenoids as indicators for a new transformation pathway in the environment.
abstract: Four oleanane-related aromatic triterpenoids isolated from an archeological piece of oak wood have been identified by NMR studies. Their structures give clue to a novel diagenetic transformation pathway of 2,3-oxygenated higher plant triterpenoids in the environment.
