A method for separating, recovering, and purifying a cannabidiolic acid amine salt (CBDA-amine salt) from an organic solvent solution comprising a mixture of cannabinoids, said method comprising: providing an extract containing therein a complex mixture of cannabinoids recovered from a cannabis biomass; assaying the extract to determine a first concentration of CBDA therein; adding to the extract a volume of a first organic solvent selected from an alkane or a petroleum ether having a boiling point of less than 100 °C, and commingling therewith to adjust the first CBDA concentration to a target concentration value selected from a range of target concentrations, thereby producing a solvent-solubilized extract solution; adding a selected amine to the solvent-solubilized extract solution and commingling therewith to precipitate therefrom a CBDA-amine salt, wherein said amine is: a tertiary amine selected from one of triethylamine, tripropylamine, tributyl amine, methyldicyclohexylamine, and quinine, or a diamine selected from one of N,N,N-trimethylethylenediamine, N,N,N,N-tetramethylethylenediamine, 4-aminomethylpiperidine, 1,5-diazabicyclooctane (DABCO), 4-dimethylaminopyridine (DMAP), 1,5-diazabicyclo[4.3.0]non-5-ene, 1,8-diazabicycloundec-7-ene, and dimethylpiperazine, or a secondary amine selected from one of diisopropylethylamine (Hunig's base), diethylamine, N-isopropylcyclohexylamine, and 2,2,6,6-tertamethylpiperidine, or an amino alcohol selected from one of piperidineethanol and N,N-dimethylethanolamine, or an amino ether selected from one of morpholine and N-methylmorpholine, or cyclohexylamine; washing the precipitated CBDA-amine salt at least once with said first organic solvent and then drying the washed CBDA-amine salt; dissolving the CBDA-amine salt in a selected second organic solvent and commingling therewith; adding a volume of a selected antisolvent to the dissolved CBDA-amine salt and commingling therewith to thereby recrystallize the CBDA-amine salt therefrom; and washing the recrystallized CBDA-amine salt at least once with said selected antisolvent to produce a purified CBDA-amine salt, and then drying the purified CBDA-amine salt. providing an extract containing therein a complex mixture of cannabinoids recovered from a cannabis biomass;
