Abstract
A novel diaryl isoprenoid 1 with an additional aromatic ring (C30H38), formed from the carotenoid beta-carotene by cyclisation, aromatisatio n and expulsion reactions during sediment diagenesis, has been isolate d from a 50 Ma old lacustrine sedimentary rock and identified by H-1 a nd C-13 NMR spectroscopy and mass spectrometry.
