Abstract

Five flavonoid glycosides were identified from flowers of Arnica montana, ten from A. chamissonis subsp. foliosa var. incana. The structures were established on the basis of acid hydrolysis and spectral data (UV, NMR, MS) as the 7-β-glucosides of pectolinarigenin, apigenin, and chrysoeriol; luteolin 3′-O-β-glucoside; the 3-β-glucuronides of kaempferol, isorhamnetin, and 6-methoxykaempferol; the 3,7-di-β-glucosides of quercetin and patuletin; the 3-β-glucosides of betuletol and quercetagetin 6,3′,4′-trimethyl ether; and the 7-[6″-O-(2-methylbutyryl)]=glucosides of luteolin and eupafolin. The latter four are new natural compounds. Differences between these two Arnica species are discussed.
