Flavonoid Glycosides and Other Hydrophilic Compounds from Flowers of Heterotheca inuloides.
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.
