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