Journal ArticleDOI
A chemical investigation by headspace SPME and GC–MS of volatile and semi-volatile terpenes in various olibanum samples
TL;DR: The chemical composition of olibanum, which is demonstrated to be different for each Boswellia species, allowed the determination of the taxonomic origin of frankincense samples purchased on various markets in East Africa, in the Near East and in Yemen.
Journal ArticleDOI
The canopic jars of Rameses II: real use revealed by molecular study of organic residues
Armelle Charrié-Duhaut,Jacques Connan,Nicolas Rouquette,Pierre Adam,Christophe Barbotin,Marie-Françoise de Rozières,Alain Tchapla,Pierre Albrecht +7 more
TL;DR: A study of two successive organic residues from the canopic jars, using molecular biomarkers analysed by GC-MS and LC-MS, and absolute dating by 14C, was initiated as discussed by the authors.
Journal ArticleDOI
A comparative geochemical study of bituminous boat remains from H3, As-Sabiyah (Kuwait), and RJ-2, Ra's al-Jinz (Oman)
Jacques Connan,Robert Carter,Harriet Crawford,Mark Tobey,Armelle Charrié-Duhaut,Dan Jarvie,Pierre Albrecht,Kirsty Norman +7 more
TL;DR: In this paper, a geochemical analysis of fragments of bituminous amalgam from H3, As-Sabiyah (Kuwait), and RJ-2, Ra's al-Jinz (Oman) dates to between 53004900 and 2500-2100 BC.
Journal ArticleDOI
A geochemical study of bituminous mixtures from Failaka and Umm an-Namel (Kuwait), from the Early Dilmun to the Early Islamic period
Jacques Connan,Robert Carter +1 more
TL;DR: In this article, the authors presented geochemical analyses of fragments of bituminous mixtures excavated from archaeological sites in Kuwait, covering a time span including the Early Dilmun period, the Kassite period and the Hellenistic to Early Islamic periods.
Journal ArticleDOI
Synthesis and NMR characterisation of novel highly cyclised polyprenoidhydrocarbons from sediments
Emmanuelle Grosjean,Jacques Poinsot,Armelle Charrié-Duhaut,Stéphanie Tabuteau,Pierre Adam,Jean M. Trendel,Philippe Schaeffer,Jacques Connan,Daniel Dessort,Pierre Albrecht +9 more
TL;DR: Two novel hexacyclic alkanes occurring in bitumen are identified as "orphan” molecular fossils of biological lipids of unknown origin formed by the extensive cyclisation of higher regular polyprenoids.
