Friedelin is a triterpenoid chemical compound found in Azima tetracantha, Orostachys japonica, and Quercus stenophylla. Friedelin is also found in the roots of the Cannabis plant. It is noted as having antimicrobial properties and has been recovered from the byproducts of corkboard manufacturing. The compound is also a biological precursor of celastrol. It is considered a friedelane-type compound, appearing structurally similar with the addition of a ketone group.
