Abstract

Polar carboxylic acid fractions of lipids extracted from samples from a 4000-year-old Nubian mummy were investigated by capillary gas chromatography mass spectrometry. They contain series of alpha,omega-dicarboxy, monohydroxy, dihydroxy and keto fatty acids, some of which were found for the first time outside the synthetic laboratory. Their chromatographic and mass spectrometric characteristic properties are reported.

摘要

采用毛细管气相色谱 - 质谱联用技术，对一具4000年前努比亚木乃伊样本中提取的脂质的极性羧酸部分进行了研究。它们含有一系列α,ω - 二羧酸、单羟基、二羟基和酮脂肪酸，其中一些是首次在合成实验室之外被发现。报告了它们的色谱和质谱特征性质。
