Fuente: WIPO "industrial hemp" A method of extracting cannabinoids from hemp and/or of producing a whole hemp extract lacking .DELTA.9-THC is herein described. The industrial hemp is harvested and the chaff is thrashed from the seeds. The chaff is then ground and the ground chaff is extracted with an organic solvent. The extract is then loaded onto a chromatographic column selected to fractionate specific cannabinoids.
