From: First evidence of terrestrial ambrein formation in human adipocere
Partial (35 min to 47 min) total ion current GC-MS chromatograms of silylated extracts of ambergris, neutral lipids of adipocere from graves (G1–G4), neutral lipids of intestinal content from adipocere sample G2 (I1) and neutral lipids of external adipocere (A1). Components (as TMS ethers): a = coprostanol; b = epicholestanol; c = epicoprostanol; d = ambrein; e = cholesterol and f = 5α-cholestanol. The ambergris extract was diluted 1:100 v/v compared to adipocere samples (G1–4; A1) and the intestinal sample (I1). Note that the major lipids of adipocere (fatty acids) are not included in the analyses.
