The development and application of analytical methods for the identification of dyes on historical textilesThe analytical investigation of several historically important natural yellow and red dye sources is presented, extending previous work on the chemical characterisation of the acid hydrolysed extracts from dyed yarns. The PDA HPLC studies of weld (Reseda luteola L.) dyed yarn extracts found that neither the substrate nor additional steps...

The analytical characterisation of the main component found in logwood dyed textile samples after hydrochloric acid extractionThe triennial meetings of the ICOM Committee for Conservation (ICOM-CC) are widely regarded as the most significant global events in the heritage conservation calendar. At each Congress, the membership of the ICOM-CC are brought together to report and to review current research. The meetings offer the conservation professional a unique...

The application of liquid chromatography–mass spectrometry and accelerated light ageing for the analytical identification of yellow flavonoid dyes in historical tapestriesPapers in this volume cover various aspects of the deterioration of textiles and the different scientific techniques that can be applied to investigate the characteristics of historic textiles, their fibres, dyes etc. The authors include textile, paper and painting conservators, conservation scientists, chemists, archaeologists, engineers, biochemists and a zoologist. This...

Journal articleThe 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...

Journal articlePolyphenolic components from Genista species have been well characterised because of their potential as antioxidants and as therapeutic leads; however, the identification of dyer's greenweed (Genista tinctoria L.) in historical textiles has been the subject of only limited studies. This paper presents a comprehensive UPLC-PDA MS/MS study of reference and...
