Abstract
- This review discusses the characterisation of natural organic dyestuffs of historical interest by liquid chromatography–mass spectrometry. The structures of the most important natural organic dyestuffs traditionally used are presented and discussed from the perspective of their analytical chemical determination. The practical aspects of the determination of this inhomogeneous range of compounds with different structures, such as anthraquinones, flavonoids, indigoids or tannins, are discussed with their implications for sample preparation, liquid chromatographic separation and mass spectrometric detection. The particular focus of this review is the discussion of the mass spectral fragmentation patterns of the different classes of natural organic dyestuffs, which in the ideal case allow the identification of the dyestuff actually used, and thereby provide a key to the better characterisation and understanding of historical objects dyed with natural organic dyestuffs.
