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 th...
