Friedelin is a triterpenoid chemical compound found in Azima tetracantha, Orostachys japonica,^[1] and Quercus stenophylla.^[2] Friedelin is also found in the roots of the Cannabis plant.^[3] It is noted as having antimicrobial properties^[4] and has been recovered from the byproducts of corkboard manufacturing.^[5] The compound is also a biological precursor of celastrol.^[6] It is considered a friedelane-type compound, appearing structurally similar with the addition of a ketone group.^[5]
