Abstract

The acid-hydrolysed extracts of freshly dyed reference fibres of sawwort harvested from several different geographical locations were characterised by the use of high-performance liquid chromatography with photodiode array detection (HPLC–PDA) and coupled with electrospray ionisation mass spectrometric analysis (HPLC–ESI–MS). A related species, Serratula coronata L. was also characterised. The flavonols quercetin, 3-O-methylquercetin and kaempferol, and the flavones luteolin and apigenin were observed in all samples. Accelerated ageing studies confirmed the sensitivity of the flavonol components to photo-oxidative degradation. The poor lightfastness and small relative proportion of these flavonol components found in the extracts of freshly dyed sawwort limits their use as sawwort ‘markers’ in historical samples.
