摘要:  目的建立凶杀案件现场遗留的微量人体脂肪残渣种属的检验鉴定方法。方法用丙酮溶解人体油脂、动物油脂,油脂溶液进行高效液相色谱-蒸发光散射分析。结果人体脂肪的液相色谱数据特征性强,与常见动物油脂差异显著,可作为鉴定人体脂肪种属的依据。检材不受各种环境因素的干扰,对于腐败的人体脂肪仍可得出准确鉴定结论。结论高效液相色谱-蒸发光散射方法是检验鉴定微量人体脂肪种属的一种有效手段。

Abstract: Objective To establish a method for identification of trace amount human fat residues at crime scenes. Method Human and animal fats are dissolved in acetone, and analyzed by high performance liquid chromatography with evaporative light-scatter detector (HPLC-ELSD). Results The chromatogram of human fat is obviously different from that of animal fats, which could be used to identify the fat of human source. Samples are not interfered by environmental factors. Even with decaying human fat, correct analysis results could still be got. Conclusion The established HPLC-ELSD method is effective in identifying trace amount human fat.
