Abstract
The article presents a method which demonstrates significantly improved extraction of lipids from archeological pots by replacing liquid organic solvents with supercritical fluids. This study also highlighted a variability of the ratio of unsaturated versus saturated fatty acids depending on the extraction method.The increased extraction efficiency provided by supercritical fluids, as well as their minimally destructive nature, enable new and refined approaches to residue analysis and dating of archeological ceramics.
