在对属于佛罗伦萨Papirologico Vitelli考古收藏的埃及陶瓷容器的研究框架中，对公元5 -7世纪的三个发现的有机残留物进行了表征。分别采用傅里叶变换红外光谱（FTIR）和气相色谱-质谱（GC-MS）两种分析方法进行鉴定。第一种方法适用于检测有机物质的官能团从而区分它们；第二种方法允许同时分析几种天然物质，如植物树脂和油、沥青、焦油和沥青以及蜡。单羧酸、α、ω -二羧酸、长链二羟基酸和萜烯酸的存在表明，尽管有机残留物在组成上表现出高度的异质性，但它们主要由植物来源的物质组成。特别是，不饱和脂肪酸氧化产物的存在表明，存在从十字花科植物种子中产生的油，据报道，其中一些在古埃及被用来生产油。此外，在三件陶器中的两件中存在特征二萜生物标志物，使我们能够评估松树脂和松沥青的使用。(C) 2004 Elsevier B.V.版权所有
In the framework of a study on the Egyptian ceramic vessels belonging to the archaeological collection of the Istituto Papirologico Vitelli (Florence), the characterisation of organic residues from three findings of the 5th-7th centuries A.D. has been performed. The materials were identified by two analytical procedures based on Fourier transformed infrared spectroscopy (FTIR) and on gas chromatography coupled with mass spectrometry (GC-MS), respectively. The first procedure is suitable for detecting the functional groups of organic substances and thus for distinguishing them; the second permits the simultaneous analysis of several natural substances such as vegetable resins and oils, bitumen, tar and pitch, and waxes.The presence of monocarboxylic acids, alpha,omega-dicarboxylic acids, long-chain dihydroxylated acids, and terpenic species, highlights that although the organic residues showed a high heterogeneity in composition, they mainly consisted of materials of vegetable origin. In particular, the presence of oxidation products of characteristic unsaturated fatty acids suggests the occurrence of oil produced from plant seeds of the Cruciferae family, some of which are reported to have been used in ancient Egypt to produce oil. Moreover, the presence of characteristic diterpenic biomarkers in two of the three pieces of pottery enables us to assess the use of both pine resin and pine pitch. (C) 2004 Elsevier B.V.
