Identification of novel C25 highly branched isoprenoid thiophene in sediments

By J.S. Sinninghe Damsté and W.I.C. Rijpstra


A novel C25 highly branched isoprenoid (HBI) thiophene, 2-(2-methylpropyl)-4-[9-(2,6,12-trimethyltetradecyl)]thiophene, has been identified in three sediment samples by isolation followed by characterization by 1H-NMR, GC-MS and Raney Ni desulphurization. This component is probably formed by incorporation of inorganic sulphur species into a specific sedimentary C25 HBI alkadiene. This latter compound is probably derived from diatoms
