Low Molecular Weight Polyphenols in Wood and Bark of <i>Eucalyptus Globulus</i>
Keywords:Wood, bark, Eucalyptus globulus, polyphenols, flavonoids, phenolic acids, phenolic aldehydes
AbstractPolyphenols (mainly flavonoids and phenolic acids and aldehydes) were studied in wood and bark samples of Eucalyptus globulus. Gallic and ellagic acids, vanillin, syringaldehyde, sinapaldehyde, and quercetin were identified in wood; and gallic, protocatechuic, vanillic and ellagic acids, protocatechuic aldehyde, taxifolin, eriodictyol, quercetin, and naringenin in bark. Ellagitannins and some unidentified flavonols were also detected in both samples.
