Ether soluble polyphenols from leaves of Eucalyptus camaldulensis, E. globulus and E. rudis have been studied. The phenolic aldehyde vanillin, the phenolic acids gallic, protocatechuic and ellagic acids, some flavonol glycosides (rutin, quercetin‐3‐arabinoside, quercetin‐3,7‐dirhamnoside, quercitrin, kaempferol‐3‐arabinoside and their aglycones), one flavanone (naringenin) and two flavones (luteolin and apigenin) were identified and quantified. Some ellagitannins, flavonols and flavanones were recognized according to their ultra‐violet spectra. E. camaldulensis and E. rudis showed the highest concentrations and varieties of flavonol glycosides, whilst E. globulus was characterized by high concentrations of ellagitannins. © 1997 John Wiley & Sons, Ltd.
