Fuente: WIPO "industrial hemp" A method for extracting broad-spectrum cannabis oil from industry hemp includes the following steps: the hemp leaves, flowers drying, crushing to obtain the material powder, the material powder was extracted by ethanol with concentration value of 60-95%(V/V) to get extract, then do the process of concentration, decarboxylation, using short-range molecular distillation to remove impurities, distillation liquid winterization, pressure filtration to remove wax, filter solution into the column to remove impurities, purification, separation. The purified ethanol chromatographic solution to be concentrated in order to remove alcohol and water product namely the broad-spectrum hemp oil, this method may obtain the product of tetrahydrocannabinol (THC) content can control below 0.1%, the product safety is high, completely satisfies the industrial production.
