From the standpoint of chemotaxonomy, components of the flavonoid in the leaves of Salix plants were examined. The leaves of Salix matsudana KOIDZ.f.tortuosa REHD. afforded chrysoeriol 7-glucuronide as yellow crystals, mp 272-274, and luteolin 7-glucuronide as yellow microneedles, mp 242-244°. Yellow needles, mp 239-240°, were isolated from the leaves of Salix gilgiana SEEMEN and identified as luteolin 7-glucoside by direct comparison.
