The subject matter of the invention is a process for concentrating spilanthol contained in a composition, comprising the formation of an addition compound of spilanthol with a strong acid, then the hydrolysis of said addition compound. The process according to the invention makes it possible to easily obtain a composition which can comprise 100% of isolated actual spilanthol ((2E,6Z,8E)-N-(2-methylpropyl)deca-2,6,8-trienamide) or of a mixture of actual spilanthol with the isomers and/or homologues thereof that may accompany it. |
