[Postmortem decomposition of neutral lipids. Use of modern methods of analysis (HPLC, capillary GC, GC-MS and NMR) in adipocere formation].
The chemical composition of subcutaneous fats was analyzed in a corpse that had died from drowning. The skin of the cadaver examined postmortem showed different stages of adipocere. Samples from these regions were chemically compared with the fatty tissue of a person who had died recently. HPLC, GC, GC-MS, NMR (1H- and 13C-NMR), TLC and titrimetrical methods were used to evaluate the degree of decomposition. The fatty acid pattern of the triglycerides (TG) and the free fatty acids (FFA) obtained by TLC separation was also investigated. Some discrepancy was observed between the autopsy findings and the results of the chemical analysis. It is suggested that the autopsy should be supplemented by chemical analysis in order to describe the state of adipocere correctly.
