(EN) IMPROVEMENTS IN THE EXTRACTION OF PHARMACEUTICALLY ACTIVE COMPONENTS FROM PLANT MATERIALS
(FR) AMELIORATION DANSL'EXTRACTION DE COMPOSANTS A ACTION PHARMACEUTIQUE A PARTIR DE MATIERES VEGETALES
Abstract
(EN)
The invention relates to the extraction of pharmaceutically active components from plant materials, and more particularly to the preparation of a botanical drug substance (BDS) for incorporation in to a medicament. It also relates to a BDS of given purity, for use in pharmaceutical formulations. In particular it relates to BDS comprising cannabinoids obtained by extraction from cannabis.
