Abstract
Five flavonoid glycosides were identified from flowers of Arnica montana, four from A. chamissonis subsp. foliosa var. incana. The structures were established on the basis of total acid hydrolysis and spectral data (UV, 1H-NMR, 13C-NMR, MS) as hispidulin 7-O-β-glucoside, isorhamnetin 3-O-β-glucoside, 3-O-β-D-glucopyranosides of spinacetin, 6-methoxykaempferol and patuletin and querectin 3-O-(6″-O-acetyl)-β-D-glucopyranoside. The latter compound can serve as distinctive marker between these two Arnica species. The 1H-NMR spectra in CD3OD are discussed.
