摘要：

Chemical investigation of the leaves and the flowers of Rhododendron ferrugineum afforded six known flavonoids: hyperoside, myricetin 3-O-beta-galactopyranoside, kaempferol 3-O-(6 "-O-acetyl)-glucoside, quercetin 3-O-(6 "-O-acetyl)-glucoside, quercetin 3-O-(6 "-O-acetyl)-galactoside, quercetin 3-O-(3 ",6 "-O-diacetyl)-galactoside and two new dihydroflavonol glycosides: trans-taxifolin 3-O-alpha-arabinopyranoside and cis-taxifolin 3-O-alpha-arabinopyranoside.
