Petasin is a natural chemical compound found in plants of the genus Petasites. Chemically, it is classified as a sesquiterpene and is the ester of petasol and angelic acid.

Petasin is believed to be responsible, at least in part, for the anti-inflammatory effects of Common Butterbur (Petasites hybridus) extracts.
