An optimised small-scale sample preparation workflow for historical dye analysis using UHPLC-PDA applied to Scottish and English Renaissance embroidery
A 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....Sandström, Edith ; Wyld, Helen ; Mackay, C Logan ; Troalen, Lore G ; Hulme, Alison N

Negative ion electrospray mass spectrometry of neoflavonoids
The electrospray ionisation mass spectra of the neoflavanoids brazilin and hematoxylin are reported in both their reduced (1 and 2, respectively) and their oxidised forms (3 and 4, respectively). In the reduced forms, breakdown pathways under collision induced decomposition (CID) conditions produce fragments characteristic of rings A and C; in...Hulme, Alison N ; McNab, Hamish ; Peggie, David A ; Quye, Anita

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
