Raman spectroscopy of coloured resins used in antiquity: dragon's blood and related substances
Dragon's blood is a deep red resin which has been used for centuries by many cultures and much prized for it's rarity, depth of colour and alchemical associations. The original source of dragon's blood resin is believed to be Dracaena cinnabari from Socotra in Africa, but since mediaeval times there...Edwards, Howell G M ; de Oliviera, Luiz Fernando C ; Quye, Anita

‘Dragon’s Blood’ I—characterization of an Ancient resin using Fourier transform Raman spectroscopy
Several resins generically known as ‘dragon’s blood’ from different botanical and geographical sources were characterised non‐destructively using Fourier transform Raman spectroscopy. Genuine ‘dragon’s blood’ resin (Dracaena spp.) as found on Socotra Island was the probable source in antiquity. The spectra of recently collected Socotran resins from different sites were compared...Quye, Anita ; Edwards, Howell G M ; Farwell, D W

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
