Analysis of organic residues from the Châteaumeillant oppidum (Cher, France) using GC–MS

Scientific analysis has provided new evidence in historical and archaeological studies recent years. Archaeological samples are frequently contaminated because of conservation conditions and/or cleaning before restoration. Roman amphora, made a material great interest, is no exception. This study develops the chemical Dressel I amphorae coming from Châteaumeillant oppidum France, dating 2nd century-1st century BC. Traces organic matter located on internal surface were identified using gas chromatography-mass spectrometry (GC–MS). analytical technique notably allows markers resinous (pitch) wine to be detected. Analytical results showing presence syringic acid, along with other acids (benzoic, succinic vanillic acids) certain context, demonstrated that vessels had contained wine. Moreover, two families resins (Pinaceae Cupressaceae) observed. They used for waterproofing or as an additive resinated In particular, observation sandarac resin (Cupressaceae) rare amphorae.
