Structure of the Sesquiterpenes of Petasites hybridus ( L. ) G. M. et SCH .: Petasol and Isopetasol Derivatives The structure of 11 compounds of the sesquiterpene fraction of petasites hybridus has been determined by combination of spectroscopic methods, especially by analysis of the 360‐MHz‐ 1 H‐NMR. spectra. Most natural products are esters of two isomeric sesquiterpene alcohols, characterized by an eremophilan skeleton, namely of petasol as well as of isopetasol . The structure of one key product has been confirmed by X‐ray analysis.
