Abstract:
The present specification discloses methods of purifying one or more cannabinoids from a plant material, purified cannabinoids and pharmaceutical compositions comprising one or more cannabinoids produced by the disclosed method, methods and uses for treating a disease or condition employing such purified cannabinoids and pharmaceutical compositions.

Claim (Index 1):
A method of purifying one or more cannabinoids from a plant material including a plant, a plant resin or a plant extract, the method consisting essentially of the following steps:\n (a) incubating the plant material with a solvent selected from the group consisting of pentane, hexane, heptane, petroleum ethers, cyclohexane, dichloromethane, trichloromethane, tetrahydrofurane, diethyl ether, toluene, benzene, ethanol, methanol, isopropanol, acetone, acetonitrile, ethyl acetate, butane, propane, refrigerant gases (e.g.: 1,1,1,2-Tetrafluoroethane (R134a)) or, liquid, subcritical or supercritical CO 2  or mixes thereof to form a solvent mixture which extracts the one or more cannabinoids from the plant material; (b) for THC-type extracts, adding to the solvent mixture a biphasic system selected from the group consisting of hexane:ethanol:water, pentane:acetonitrile and hexane:acetonitrile, wherein the pentane:acetonitrile system and the hexane:acetonitrile system optionally include ethyl acetate and/or water as a modifier; for CBD-type extracts, adding to the extract a biphasic system of hexane:ethanol:water; and for CBG-type extracts, adding to the extract a biphasic system of hexane:ethanol:water; and (c) performing liquid:liquid chromatography, thereby purifying the one or more cannabinoids.
