“…These natural dyes give very attractive non-uniform colors, which present differences in shade and intensity around a certain hue that create the illusion of movement-a vibrato effect [2]. Although we have evidence that the sources for red and blue were widely traded [1], recent research has shown that yellow dye plants may have been regional [3][4][5]. This was corroborated in our case study on natural yellow dyes used in Isfahan, a province in the central part of Iran (covering an area of 107,029 km 2 ).…”

“…The fundamental yellow chromophores that were extracted from these plants are flavonoids based on the flavone and flavonol chromophore, Figures 1-3. In literature, flavone-based yellows are considered more stable than flavonols, but the latter might be stabilized by transforming the OH group in position 3 into an O-glycoside [5,11].Molecules 2019, 24, x FOR PEER REVIEW 2 of 17…”

This work provides new knowledge on natural yellows used in Iran. Seven biological sources were selected based on interviews with dye masters in Isfahan workshops (Iran). Delphinium semibarbatum, Eremostachys laevigata, Prangos ferulacea, Morus alba, Pistacia vera, Punica granatum, and Vitis vinifera are currently used in these workshops. Aiming to study the dye composition of wool samples dyed with the extracts of the selected biological sources, and the changes induced by the dyeing procedures in the original chemical composition of the plant extract, raw materials and dyed wool (by us and in the workshops) were analyzed by HPLC–DAD and UHPLC–HRMS/MS. In solutions extracted from the textiles, the main yellows for E. laevigata are luteolin-O-glycosides. In the other plant sources, the main chromophores are based on 3-O-glycosides of kaempferol, quercetin, and isorhamnetin. In pistachio hulls, myricitin derivatives were detected and we propose their use as markers. Generally, the solutions extracted from the wool displayed a higher amount of more polar compounds, but also a higher amount of aglycones. Importantly, the chromatographic profiles of the samples we prepared compared well with 17th c. yellows in Persian carpets, and therefore can be considered highly characterized references for the study of Persian yellows.

“…Natural red organic dyes of both vegetable and animal origin (plants such as brazilwood, and insects such as cochineal) and their complexes have been used by artists for artworks since Antiquity [1]. These complexes, known as lake pigments, and their paints are generally composed by the colored dye and its complexing metal ion (aluminum, in most cases), the inorganic component, and the binder.…”

Abstract. Our cultural heritage is constituted by irreplaceable artworks that must be known and preserved. Their study and documentation should be in principle carried out using non-invasive approaches. The technological advances in spectroscopic imaging acquisition devices made it possible to apply this methodology to such purpose. In this context, the present paper discusses a particularly challenging task within the conservation field, which is the identification of red lake pigments in artworks, applying Vis-NIR hyper-spectral imaging spectroscopy. The latter was used to characterize and discriminate between historically accurate paint reconstructions of brazilwood (vegetal) and cochineal (animal) lake pigments. The same paints were also analyzed with Fiber Optic Reflectance Spectroscopy to validate the data obtained with the imaging method. The requirements for a successful identification of these pigments are addressed, and future research is suggested in order to increase the usefulness of the technique's application.

“…This pre-eminence over synthetic chemicals is probably derived from evolutionary pressures in Nature to develop chemicals that bind selectively to specific biomolecules thus giving the producing organism some advantage over competitors [2,3,4]. Terrestrial natural products have been used as dyes since ancient times [5]. However, drugs and dyes derived from marine sources are relatively rare probably because of the difficulties associated with supply and availability.…”
