| Abstract: | A 28-year-old male methamphetamine abuser, who had been buried for 5 years after being killed by strangulation, was found skeletonized. Methamphetamine and amphetamine in the significantly denatured fatty material of the bone marrow were analyzed by gas chromatography and gas chromatography-mass spectrometry. The confirmation of the chemicals was carried out by chemical ionization (CI) mass chromatography, CI mass spectrometry and CI mass fragmentography. The concentrations of methamphetamine and amphetamine determined by CI mass fragmentography were 1.0 mumol/100 g and 0.1 mumol/100 g, respectively. The method used would seem to be very useful for determination of methamphetamine and amphetamine in marked putrefied biological materials. |
