Abstract:
A method for purification and separation of cannabinoids, such as cannabidiol and tetrahydrocannabinol, e.g., from dried hemp and  cannabis  leaves can use a continuous simulated moving bed process, a batch column chromatography method, or a single column, and a combination of one or more of a sequence of purification steps including: filtration, decolorization, activation or decarboxylation, dewaxing, polishing, and crystallization to separate a cannabinoid from the  cannabis  plant and to provide various cannabinoid products. The cannabinoid products can be used in various pharmaceutical and nutraceutical applications.

Claim (Index 1):
A method of separating a cannabinoid of a  cannabis  plant, the  cannabis  plant including the cannabinoid and at least one impurity, the method comprising:\n preparing a feedstock stream, the feedstock stream including the  cannabis  plant and a solvent; passing the feedstock stream through a chromatographic resin to provide an eluate stream, the eluate stream having a higher purity of the cannabinoid than in the feedstock stream as measured by weight percentage of the solid content, wherein the chromatographic resin comprises at least one of:\n a first resin, the first resin comprising a modified activated carbon adsorbent having an average particle size range of from about 45 to about 1700 microns, \n a second resin, the second resin comprising a modified hydrophobic adsorbent having an average bulk density of from about 0.4 g/mL to about 0.6 g/mL, the modified hydrophobic adsorbent comprising at least one of a styrene-divinylbenzene (DVB) resin or a poly(methyl methacrylate) (PMMA) resin, \n a third resin, the third resin comprising a hydrophobic resin having an average bulk density of from about 0.75 g/mL to about 0.85 g/mL, \n a fourth resin, the fourth resin comprising a hydrophobic polystyrene-divinylbenzene adsorbent having a water content of from about 55% to about 65%, and \n any mixture thereof.
