Abstract
Novel aromatic carotenoid derivatives 7 and 8 have been identified by synthesis of reference compounds in a H-2/PtO2-hydrogenated fraction f rom the organic extract of a lake sediment (lake Cadagno, Switzerland) . They derive from unreported carotenoids presumably biosynthesized by purple sulfur photosynthetic bacteria (Chromatiaceae) and represent p otential biomarkers to establish the occurrence of photic zone anoxia in ancient ecosystems.
