Friedelane is an aliphatic chemical compound and natural product. Its formula is C₃₀H₅₂.^[1] Friedelane is a triterpene, and it and similar compounds are found in several plants.^[2] One such compound found in the bark of cork oak, friedelin, is considered a "friedelane-like",^[3] and has noted antimicrobial properties.^[4] It is also a biological precursor of celastrol.^[5]

Occurrence

Friedelane is found in the wood of Calophyllum tomentosum,^[6] as well as the flowers of Pongamia pinnata.^[7]
