To these acids may be correlated some of the medicinal activities ascribed to those species. The ethanolic extract of Solidago microglossaafforded, as principal constituent from the aerial parts quercetrin. The activity of these glicoside against cappilary fragility is well known, justifying the use of Solidago microglossa as succedaneous of Arnica montana.
