Abstract
A method of removing THC and/or THCA from a mixture is provided, the mixture including at least one other cannabinoid. The method comprises passing a first feedstock stream through a first chromatographic resin arranged in a simulated moving bed (SMB) chromatography configuration to provide a primary raffinate stream, preparing a second feedstock stream, the second feedstock stream comprising the primary raffinate stream or a concentrated primary raffinate stream, and passing the second feedstock stream through a second chromatographic resin to provide an eluate stream, the eluate stream having less than 0.3 wt % THC on a solvent free basis. The cannabinoid products can be used in various pharmaceutical and nutraceutical applications.
