摘要:

选取距今约1000多年、五代十国时期规模最大的江苏南京南唐二陵壁画为研究对象,采用热裂解-气相色谱/质谱联用(Py-GC/MS)分析技术,在对蛋清标准样品测试条件进行优化的基础上,评估了8种无机矿物颜料(方解石、铅丹、赭石、朱砂、石青、石绿、雌黄和雄黄)对蛋清裂解产物的影响,建立了针对墓葬壁画中蛋清鉴别的Py-GC/MS分析方法。文物样品的分析结果表明,壁画地仗和灰浆中均有加入蛋清作为胶结材料,同时使用酶联免疫吸附测定(ELISA)验证了Py-GC/MS分析结果,进一步说明Py-GC/MS是一种针对墓葬壁画中蛋清成分可靠的分析方法,为墓葬壁画有机胶结材料的研究提供了方法借鉴。

Abstract:

The mural paintings of the Second Tomb of the Southern Tang Dynasty in Nanjing, Jiangsu Province, which is the largest in scale during the Five Dynasties and Ten Kingdoms period in southern China, are selected as the objects of study, on the basis of optimization of the test conditions of the egg white standard samples by using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) analysis technique. Eight inorganic mineral pigments such as calcite, lead tetroxide, ochre, cinnabar, azurite, mineral green, orpiment and realgar on the cleavage products are evaluated for the first time and a method is established for the identification of egg whites in the tomb murals. The Py-GC/MS analytical method is developed for the identification of egg whites in tomb murals. The results of the analysis of the artifact samples show that egg whites are added to the mural ground battles, mortars and pigments as cementing materials, and the results of the Py-GC/MS analysis are verified using enzyme-linked immunosorbent assay (ELISA), further demonstrating that Py-GC/MS is a reliable analytical method for egg white composition in tomb murals. This study provides a methodological reference for the study of organic binding media in tomb murals.

Key words: Tomb murals, Egg white, Pyrolysis-gas chromatography/mass spectrometry, Inorganic pigment, Enzyme-linked immunosorbent assay
