(FR) NOUVEAU PROCÉDÉ DE CONCENTRATION DE SPILANTHOL ET/OU DE SES ISOMÈRES ET/OU HOMOLOGUES
Abstract:
(EN) 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.
(FR) L'invention a pour objet un procédé de concentration du spilanthol contenu dans une composition, comprenant la formation d'un composé d'addition du spilanthol avec un acide fort, puis l'hydrolyse dudit composé d'addition. Le procédé selon l'invention permet d'obtenir facilement une composition pouvant comprendre 100% soit de spilanthol vrai ((2E,6Z,8E)-N-(2-methylpropyl)deca-2,6,8-trienamide) isolé, soit d'unmélange de spilanthol vrai avecses isomères et/ou homologues qui peuvent l'accompagner.
