Noninvasive characterization and quantification of anthraquinones in dyed woolen threads by visible diffuse reflectance spectroscopyThe anthraquinone components of the roots of various species of madder (like Rubia tinctorum L. and Rubia peregrina L.) have been used for millennia as red colorants in textiles, carpets, tapestries, and other objects. To understand the selection and preparation of dyestuffs in various cultures and historical periods, these dyes...

An optimised small-scale sample preparation workflow for historical dye analysis using UHPLC-PDA applied to Scottish and English Renaissance embroideryA sample preparation workflow for historical dye analysis based on 96 well plates and filtration by centrifugation was developed. It requires less sample and the introduced error is decreased, making it useful for culturally important objects. A sample preparation workflow for historical dye analysis requiring less sample has been developed....
