SYSTEMS AND METHODS FOR CANNABIS CBD EXTRACTION
Systems and methods for extracting a compound of interest from plant material, such as a cannabidiol (CBD) from cannabis, are provided. Particularly, the disclosed systems and methods utilize a crude oil to separate water and impurities including fats, sugars, resin glues, chlorophyll, and proteins prior to preparation of a CBD distillate. The systems and methods are operable to remove the impurities from the crude oil with a brine solution and at least one acid prior to distillation. The systems and methods are operable with conventional solvents containing between about 5 wt % and about 8 wt % water.

METHODS FOR EXTRACTION, PROCESSING, AND PURIFICATION OF A SELECTED FAMILY OF TARGET COMPOUNDS FROM CANNABIS
Disclosed are methods for separating, recovering, and purifying cannabidiolic acid (CBDA) salts from an organic solvent solution comprising a mixture of cannabinoids. The methods comprise solubilizing the mixture of cannabinoids in C5-C7 hydrocarbon solvents, adding thereto a selected amine to thereby precipitate a CBDA-amine salt therefrom, dissolving the recovered CBDA-amine salt in a selected solvent and then adding thereto a selected antisolvent to thereby recrystallize a purified CBDA-amine salt therefrom. The recrystallized CBDA-amine salt may be decarboxylated to form a mixture of cannabidiol (CBD) and amine. The CBD amine mixture may be acidified to separate the amine from CBD. Also disclosed are CBDA-amine salts produced with certain amines selected from groups of secondary amines, tertiary amines, diamines, amino alcohols, amino ethers, and highly basic amines.

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.
