Struktur der Sesquiterpene von Petasites hybridus (L.) G. M. et SCH.: Neopetasol‐Abkömmlinge

Abstract
Structure of Sesquiterpenes of Petasites hybridus (L.) G. M. et SCH.: Derivatives of NeopetasolThe structure of 5 compounds of the sesquiterpene fraction of petasites hybridus has been determined by combination of spectroscopic methods, especially by analysis of the 360‐MHz‐1H‐NMR. spectra. Most natural products are esters of a sesquiterpene alcohol, which is the 7 β‐epimer of petasol. The alcohol is named neopetasol.
