Title
(EN) EXTRACTION METHOD AND NOVEL ACTIVE FRACTION FROM THERAPEUTIC CANNABIS PLANT EXTRACTS
(FR) PROCÉDÉ D'EXTRACTION ET NOUVELLE FRACTION ACTIVE OBTENUE À PARTIR D'EXTRAITS THÉRAPEUTIQUES DE PLANTES DE CANNABIS
Abstract
(EN)
An improved process for producing various types of cannabis extract from harvested cannabis wherein a quantity of harvested cannabis, which typically includes the inflorescence, floral leaves, and small stems of a flowering cannabis plants, is frozen and subjected to cryogenic grinding to produce pulverized cannabis. The pulverized cannabis is then subjected to alcohol extraction to produce an initial cannabis extract that is filtered to yield a remainder fraction and a filtrate. The filtrate is subjected to decarboxylation to yield active cannabinoids. The remainder fraction potentiates the activity of cannabis formulations while the filtrate can be subjected to one of several forms of further processing according to the desired chemical profile of the final product.

L'invention concerne un procédé amélioré de production de divers types d'extraits de cannabis à partir de cannabis récolté, dans lequel une certaine quantité de cannabis récolté, qui comprend typiquement l'inflorescence, les feuilles florales et les petites tiges d'une plante de cannabis en fleur, est congelée et soumise à un broyage cryogénique pour produire du cannabis pulvérisé. Le cannabis pulvérisé est ensuite soumis à une extraction par l'alcool pour produire un extrait initial de cannabis qui est filtré pour produire une fraction restante et un filtrat. Le filtrat est soumis à une décarboxylation pour produire des cannabinoïdes actifs. La fraction restante potentialise l'activité des formulations de cannabis tandis que le filtrat peut être soumis à l'une des quelques formes de traitement ultérieur en fonction du profil chimique souhaité du produit final.
