    摘要： A method for producing full spectrum hemp extract comprising extracting substances from cannabis-based green material that are soluble in an extraction solvent and collecting an extract that includes the extraction solvent distilling at least a portion of the extraction solvent which results in a concentrate that is not distilled off, removing at least a portion of water soluble substances from the concentrate by partitioning the at least a portion of water soluble substances into an aqueous phase and a remainder of substances from the concentrate into a partitioned concentrate, heating the partitioned concentrate to evaporate the nonpolar solvent and to yield a crude oil, degassing the crude oil by heating it which results in a degassed crude oil, performing a first pass distillation at about 150° C. and collecting a first residue, performing a second and third pass distillation at about 170° C. and about 185° C., and collecting a distillate from same.
