Title
(EN) PROCESS AND APPARATUS FOR MULTI-PHASE EXTRACTION OF ACTIVE SUBSTANCES FROM BIOMASS
(FR) PROCESSUS ET APPAREIL D'EXTRACTION MULTIPHASE DE SUBSTANCES ACTIVES D'UNE BIOMASSE
Abstract
(EN)
A method for performing a multi-phase extraction of plant biomass to obtain active substances is provided. The method uses a novel freeze-dry extraction technique to obtain a volatile terpene fraction from frozen plant material. In particular, the method disclosed provides terpene extracts with compositions that strongly resemble that of the parent plant material.
(FR)
L'invention concerne un procédé de réalisation d'une extraction multiphase de biomasse végétale pour obtenir des substances actives. Le procédé utilise une nouvelle technique d'extraction par lyophilisation pour obtenir une fraction de terpène volatile à partir de matière végétale congelée. En particulier, le procédé divulgué fournit des extraits de terpène ayant des compositions qui ressemblent fortement à celles de la matière végétale parent.
