It is isolated from the rhizomes of Convallaria majalis and exhibits significant cytotoxicity against human submandibular gland carcinoma (HSG) cells. It has a role as a metabolite. It is a trisaccharide derivative, a 3beta-hydroxy steroid, a 17alpha-hydroxy steroid and a steroid saponin. It derives from a hydride of a (25S)-5beta-spirostan."}]
