Abstract
A novel tetrahydrophenanthrene derivative 1 (1,1,7,8-tetramethyl-1,2,3,4-te trahydrophenanthrene), formed from the triterpenoid tetrahymanol 2a by dehy dration, ring A and B degradation and aromatisation during sediment diagene sis, has been isolated from a 180 Ma old marine sedimentary rock and identi fied by H-1 and C-13 NMR spectroscopy and mass spectrometry.
