Title (EN) METHOD FOR PURIFYING CANNABINOID COMPOUNDS
(FR) PROCÉDÉ DE PURIFICATION DE COMPOSÉS CANNABINOÏDES
Abstract:
(EN) The present invention relates to methods for purifying one or two cannabinoid compounds using simulated moving bed chromatography, wherein the cannabinoid compound(s) is/are obtained in the extract and/or the raffinate with the total amount of isomeric impurities being below detection level. In particular, the present invention relates to methods for the purification of cannabidiol, trans-(-)-delta-9-tetrahydrocannabinol, cannabidivarin, trans-(-)-delta-9-tetrahydrocannabivarin and cannabigerol which have been obtained by enantiopure synthesis.
(FR) La présente invention concerne des procédés de purification d'un ou de deux composés cannabinoïdes à l'aide d'une chromatographie à lit mobile simulé, ledit composé cannabinoïde étant obtenu dans l'extrait et/ou le raffinat, la quantité totale d'impuretés isomères étant inférieure à un niveau de détection. Plus précisément, la présente invention concerne des procédés de purification de cannabidiol, de trans-(-)-delta-9-tétrahydrocannabinol, de cannabidivarine, de trans-(-)-delta-9-tétrahydrocabovarine et de cannabigérol qui ont été obtenus par synthèse énantiopure.
