✦ Synopsis
Polyphenols of adult leaves from
Eucalyptus globulus, E. camaldulensis and E. rudis grown in Spain, in two areas with different edaphoclimatical characteristics, were estimated by chemical methods and by high pressure liquid chromatography. Leaf extracts consisted mainly of proanthocyanidins, ellagitannins and flavonol glycosides. Knowledge of the ellagitannins allows the discrimination of the three species, with E. globulus being well differentiated from the other two. However, the pattern of flavonol glycosides only permitted the discrimination of E. rudis with respect to E. camaldulensis and E. globulus.
