title: Investigation of the triacylglycerol composition of iceman's mummified tissue by high-temperature gas chromatography.
abstract: The pattern of intact triacylglycerols of a skin sample from the 5300-year-old Iceman mummy (nicknamed Otzi) was resolved on a diphenyl-dimethylpolysiloxane stationary phase by high-temperature gas chromatography. Adipocere from a 64-year-old glacier mummy as well as recent human subcutaneous fat served as a comparison in this study. Qualitatively, the results for mummy samples were similar with well-preserved saturated, but decomposed unsaturated, triacylglycerols, the latter being predominant in subcutaneous fat. Excellent preservation of triacylglycerols with odd carbon numbers and branched acyl chains was observed. The results presented here shed new light on the process of mummification.
