Abstract:
Ten flavonoid glycosides were identified in flowers of HETEROTHECA INULOIDES ("Mexican Arnica"). Their structures were established by spectral data (UV, (1)H-NMR, (13)C-NMR, mass) and total acid hydrolysis as kaempferol 3-beta-glucoside, 3-beta-galactoside, 3-beta-rutinoside, 3-beta-robinobioside, quercetin 3-beta-glucoside, 3-beta-galactoside, 3-beta-glucuronide, 3-beta-glucuronide-6''-methylester, 3-alpha- L-arabinoside, and 3-beta-rutinoside. Additionally, caffeic, protocatechuic, and chlorogenic acid as well as umbelliferone were found.
