The fate of lipids in archaeological burials
Geochemical techniques have been developed in order to systematically analyse soils collected from several burial sites. Through the extraction and GC analysis of burial soils organic signatures that inform an understanding of the burial environment, including aspects relating to the individual or c...

Geochemical techniques have been developed in order to systematically analyse soils collected from several burial sites. Through the extraction and GC analysis of burial soils organic signatures that inform an understanding of the burial environment, including aspects relating to the individual or culture in which they lived, have been obtained. GC analysis revealed that the profiles of several lipid signatures found in the burial soil samples, including n-alkanes, n-alkanals, n-alkanols, fatty acids and steroids, have shown similarities to signatures relating to degraded human adipose tissue and bacterial signatures. The abundance of lipid signatures increases around the skeletal remains, particularly the gut region, which suggests that these components are present because of the remains. Fatty acids and steroids have been typically found in the analysis of tissues from mummies and bog bodies and are also present in adipocere, although the oxidative degradation products (hydroxy fatty acid and diacids) that have also been observed in these tissues have been absent during this study.
