title: Oleanane-type triterpenoid saponins from Silene armeria.
abstract: Twelve triterpenoid saponins, including seven compounds (i.e., armerosides A-G) hitherto unknown, were isolated from whole plants of Silene armeria. Their structures were established based on extensive spectroscopic analyses and chemical methods. From a biosynthetic perspective, C-23 oxidation of the sapogenin appears to be a key factor in the glycosylation pathway.
