2',4',6'-Trihydroxy-1-methoxyacetophenone monohydrate at 150 K
The geometry of the title compound, 2-methoxy-1-(2,4,6-trihydroxyphenyl)ethanone, C9H10O5·H2O, is determined by the presence of an intramolecular hydrogen bond; the geometry of the benzene ring is distorted by a flanking carbonyl group.Ferreira, Ester S B ; Hulme, Alison N ; McNab, Hamish ; Quye, Anita ; Parsons, S

Development of analytical techniques for the study of natural yellow dyes in historic textiles
Interest in all aspects of dyestuffs has grown considerably since an informal meeting of researchers twenty years ago developed into the annual meetings of Dyes in History and Archaeology, with the journal of the same name publishing a selection of papers presented. Analysis has revealed that the early 20th-century clothing...Ferreira, Ester S B ; Quye, Anita ; McNab, Hamish ; Wouters, J ; Boon, J J …

The natural constituents of historical textile dyes
The sources and structures of dyes used to colour Western historical textiles are described in this tutorial review. Most blue and purple colours were derived from indigo—obtained either from woad or from the indigo plant—though some other sources (e.g. shellfish and lichens) were used. Reds were often anthraquinone derivatives obtained...Ferreira, Ester S B ; Hulme, Alison N ; McNab, Hamish ; Quye, Anita

Negative ion ESI–MS analysis of natural yellow dye flavonoids : an isotopic labelling study
Flavonoids are amongst the most commonly used natural yellow colourants in paintings, as lakes, and in historical textiles as mordant dyes. In this paper, evidence from isotopically labelled substrates is used to propose negative ion electrospray collision induced decomposition mechanisms of flavones, flavonols and an isoflavone. These mechanisms include a...McNab, Hamish ; Ferreira, Ester S B ; Hulme, Alison N ; Quye, Anita
