Gedunin is a pentacyclic triterpenoid with the molecular formula C28H34 O7. It is most notably found in Azadirachta indica,[1] but is a constituent of several other plants. Gedunin shows therapeutic potential in the treatment of leukemia,[2] and Parkinson's disease.[3][4]

Natural occurrence[edit]

Azadirachta indica[5] is the most notable source of gedunin, but it has also been found in the following plants:
