Method for the production of cannabinoids from types of industrial hemp |
| abstract |
The present invention describes a process for the production of (−)-cannabidiol (CBD) from industrial hemp by means of an extraction followed by two alternative working processes: a process A which provides extraction with solvents first to an alkaline pH and then to acidic pH to isolate the carboxyl form of the CBD which is then subjected to decarboxylation and a process B which provides the elimination of waxes and pitches and then purification by chromatography. At the end of both alternative working processes the CBD is crystallized obtained in high purity crystalline form. |
