✦ Synopsis

A novel tetrahydrophenanthrene derivative I (l,l,7,8-tetramethyl-l,2,3,4tetrahydrophenanthrene), formed from the triterpenoid tetrahymanol 2a by dehydration, ring A and B degradation and aromatisation during sediment diagenesis, has been isolated from a 180 Ma old marine sedimentary rock and identified by ~H and J3C NMR spectroscopy and mass spectrometry.

Naturally occurring diterpenoid tanshinones have attracted particular attention from medicinal chemists and clinicians because many of them exhibit interesting physiological properties. 1 Cryptotanshinone 1, a typical diterpenoid tanshinone from Salvia miltiorrhiza Bunge, was found to exhibit enzyme
