Title (EN) PROCESS FOR THE PRODUCTION OF IRONES
(FR) PROCEDE DE PRODUCTION D'IRONES
Abstract:
(EN) A process for the preparation of irones by a chemical oxidation of irone precursors, comprising treating an iris rhizome substrate selected from the group consisting of iris rhizomes, parts of such rhizomes, iris extracts, iris extraction wastes, any plant tissues containing precursors of irones and mixtures thereof, is described.
(FR) L'invention concerne un procédé pour la préparation d'irones par oxydation chimique de précurseurs d'irone. Ce procédé consiste à traiter un substrat de rhizome d'iris sélectionné dans le groupe se composant de rhizomes d'iris, de parties de ces rhizomes, d'extraits d'iris, de déchets d'extraction d'iris, et tous les tissus des plantes contenant des précurseurs d'irones et des mélanges de ces derniers.
