Abstract (en)
[origin: WO2019145552A1] The present specification discloses methods of purifying one or more cannabinoids from a plant material using unique biphasic solvent systems and liquid-liquid chromatography as centrifugation partitioning chromatography (CPC) or counter current chromatography (CCC). The present specification also provides purified cannabinoids such as CBG, CBGA, CBGV, CBD, CBDA, CBDV, THC, THCA and THCV, compositions comprising one or more of these cannabinoids produced by the disclosed method, and methods for treating a disease or condition employing such purified cannabinoids and compositions.
