Process for purification of tetrahydrocannabinolic- and cannabidiolic acid from plant material extract
The present invention relates to a highly economic process for the purification of a cannabinoid acid, more specifically THCA or CBDA, from either a crude cannabis plant material or a cell culture of said cannabis plant, using ion exchange resins. The purified cannabinoid acid obtained may then be decarboxylated to yield the corresponding cannabinoid, i.e., THC or CBD, respectively.
Systems and methods for extraction of biomass materials
Some variations provide a system for extracting a product from biomass, comprising: a process chamber having an internal volume; one or more mechanical elements configured to controllably and reversibly mechanically seal the process chamber and reduce the internal volume to mechanically compress the biomass; a fluid port in flow communication with the process chamber; and a collection sub-system in flow communication with the fluid port. Other variations provide a method of extracting a product from biomass, the method comprising: introducing biomass into a process chamber; mechanically sealing the process chamber; mechanically compressing the biomass to release a first fluid material; mechanically decompressing the biomass; introducing an extraction solvent into the process chamber; maintaining process-chamber pressure from about 1 bar to about 1000 bar, wherein the extraction solvent extracts a second fluid material; and recovering the second fluid material from the process chamber. High processing throughput is enabled with this invention.

Water-based extraction and purification processes for cannabinoid acids
The present invention relates to methods of extracting cannabinoid acids from cannabis plant material by combining the plant material with an aqueous solution having a high pH to solubilize cannabinoid acid anions, followed by precipitation of the cannabinoid acids at low pH and filtration. The method provides yields of up to 97%, while high pH purification of ethanol extracted oils yielded purities up to 86%.
