Historical importance
Summary of results
Multiple flavonoids, luteolin, apigenin, chrysoeriol and their glycosides were identified from desert poplar dyed wool samples.
Comments: • Acid hydrolysis showed significant amounts of flavone glycosides, probably luteolin and chrysoeriol glucuronides, which are known to be resistant to acid hydrolysis, as well as luteolin and chrysoeriol. • Other methylated derivatives of luteolin may also be present.
