“…A prerequisite for a successful analysis is the intact isolation of all dyes. Until fairly recently strong mineral acids were employed to release dyes [9,21,22], e.g., from metals used for mordanting. Unfortunately, this leads to the hydrolysis of glycosidic dyes, such as those present in weld, and then no representative fingerprint is obtained.…”

Detailed knowledge on natural dyes is important for agronomy and quality control as well as the fastness, stability, and analysis of dyed textiles. Weld (Reseda luteola L.), which is a source of flavone-based yellow dye, is the focus of this study. One aim was to reduce the required amount of dyed textile to ≤50 μg for a successful chromatographic analysis. The second aim was to unambiguously confirm the identity of all weld flavones. By carrying out the extraction of 50 μg dyed wool with 25 μL of solvent and analysis by reversed-phase UHPLC at 345 nm, reproducible chromatographic fingerprints could be obtained with good signal to noise ratios. Ten baseline separated peaks with relative areas ≥1% were separated in 6 min. Through repeated polyamide column chromatography and prepHPLC, the compounds corresponding with the fingerprint peaks were purified from dried weld. Each was unequivocally identified, including the position and configuration of attached sugars, by means of 1D and 2D NMR and high-resolution MS. Apigenin-4′-O-glucoside and luteolin-4′-O-glucoside were additionally identified as two trace flavones co-eluting with other flavone glucosides, the former for the first time in weld. The microextraction might be extended to other used dye plants, thus reducing the required amount of precious historical textiles.

The Alphabet Reform painting which shows Ataturk teaching the new alphabet is important for the history of the Republic of Turkey. This painting was made by Nazmi Ziya GÜRAN in 1933. The painting is now maintained by the Ministry of Interior. In this work, the Alphabet Reform painting was analyzed for characterization and restoration purposes. The fabric of the canvas, pigments (organic-inorganic) and the binder of paint were characterized by Fourier Transform infrared spectroscopy-attenuated total reflectance (ATR-FTIR), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) and highperformance liquid chromatography-coupled with diode array detection (HPLC-DAD) analysis methods. The CIEL*a*b* color parameters of the paint were determined by color measurement spectrophotometer. According to the results, the canvas was found to be of fibers of vegetable origin and the binders were determined to be linseed oil and dammar varnish. Red alizarin (madder lake organic pigment) and dark blue ultramarine pigments were detected as the organic pigments while CdS (yellow), Pb red (flesh color), PbCO3 (white), ZnO (white), BaSO4 (white), FeO (brown) and Cr2O3 (green color) were detected as the inorganic ones.

“…Partial hydrolysis of pseudopurpurin and munjistin was reported by Wouters [13] during dye extraction from textile fibres in the original HCl-extraction procedure. The HCl-based extraction procedure is still a widely accepted approach [41,54,[125][126][127][128][129][130][131][132] with modifications to hydrolysis conditions [116,133,134] and use of alternative solvents solvents (MeOH [116,135], DMF [136], MeOH/DMF [137,138], MeOH/formic acid [139], DMSO [50,140,141]…”

“…Reversed-phase high-performance liquid chromatography (RP-HPLC) is the most common mode for separation of historical anthraquinone dyes [15]. The most employed experimental procedure for the RP-HPLC analysis of anthraquinone dyes generally involves a C18 [13,42,131,144,146,150,156], C8 [143] or C4 [10,148] based non-polar stationary phase and mobile phases consisting of pure water (aqueous) and acetonitrile or MeOH (organic) eluents [15], with formic acid [6,148,157,158], trifluoroacetic acid [131,136,146,150,159], phosphoric acid [137,160] or methanesulphonic acid [161] added as mobile phase modifiers.…”

Historical and archaeological textiles are among the most crucial and vulnerable records of our social and cultural history. Analysis of organic colorants found in these materials is unquestionably one of the most powerful tools to understand historical developments, cultural exchanges, and progress in science and technology. Natural anthraquinones represent the most commonly used natural colorants for textile dyeing until the late 19 th century. The identification of anthraquinones in cultural heritage objects is a challenging task due to the small size of historical samples, diversity of potential dye sources, variable extraction procedures and dyeing methods, complex chemical constitution, structurally analogous chromophores, and possible presence of degradation products and contaminants. Developments in dye analysis of historical interest have originated and expanded along with the general advances in analytical science. In the last few decades, a close cooperation between science and cultural heritage disciplines contributed enormously to this field. The topic of historical dyes and their analysis in textiles, artworks, archaeological objects and cultural heritage materials has been reviewed several times in the last fifteen years. However, no review has been published to-date exclusively on the analysis of anthraquinone colorants in historical and archaeological textiles. Overall, liquid chromatography (LC)-based techniques have been the most widely used method for anthraquinone dye analysis. Owing to increasing demand of minimally invasive/non-invasive techniques, recent developments of novel techniques have resulted in the availability of many alternative/complementary methods to LC-based analysis. This review begins with a short overview of sources, chemistry and importance of natural anthraquinone dyes found in historical textiles before turning to a detailed discussion on developments involving established and emerging analytical techniques of anthraquinone dye analysis for textile cultural heritage materials. To illustrate the state-of-the-art, representative examples of analytical techniques highlighting their advantages, limitations and applicability are also presented.
