In this study we determined the concentration of fl avonoids and tannins in Salix alba, S. alba var. vitellina, and
S. alba S. blanda. Th e highest concentrations of these compounds were observed in leaves. In infl orescences, the
concentration of fl avonoids and tannins is at maximum during the full bloom; in leaves, during the phase of active
growth and in the end of the vegetation period before defoliation.
