Abstract (en)
[origin: WO2009152917A2] Described is a method for slowing the speed of the isomerisation of petasin and neopetasin to isopetasin, and the isomerisation of S-petasin and neo-S-petasin to iso-S-petasin, especially in extracts from plants of the genus Petasites, preferably Petasites hybridus, by the addition of at least one suitable stabilizer and/or the removal of at least one destabilizing substance, e.g. a fatty acid.
