Metabolite Identification
Common NameSmilagenin
DescriptionSmilagenin, also known as isosarsapogenin, 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 lipid molecule. Smilagenin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
