Common NameSmilagenin
DescriptionSmilagenin, also known as isosarsapogenin or tigogenin, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Thus, smilagenin is considered to be a sterol. Based on a literature review a significant number of articles have been published on Smilagenin.
