    • Chemical Class:

      A pentacyclic triterpenoid that is lupane in which the hydrogen at the 3<stereo>beta</stereo> position is substituted by a hydroxy group. It occurs in the skin of lupin seeds, as well as in the latex of fig trees and of rubber plants. It is also found in many edible fruits and vegetables. ChEBI CHEBI:6570
