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, the method consisting essentially of the following steps:\n a) incubating the plant material with a non-polar solvent selected from the group consisting of petroleum ether, pentane, hexane and heptane to form a first solvent mixture which extracts the one or more cannabinoids from a plant material; b) reducing the volume of the first solvent mixture to about 50% or less of the original volume of the first solvent mixture in step (a) thereby concentrating the one or more cannabinoids; c) incubating the reduced first solvent mixture at a temperature range of between about \u221270\u00b0 C. to about 40\u00b0 C. to crystalize the one or more cannabinoids; d) incubating the one or more crystalized cannabinoids with the non-polar solvent, wherein the non-polar solvent is the same non-polar solvent as in step (a) to form a second solvent mixture, thereby dissolving at least 50% of the one or more crystalized cannabinoids; and e) incubating the second solvent mixture at a temperature range of between about \u221270\u00b0 C. to about 40\u00b0 C. to crystalize the one or more cannabinoids, and f) washing the crystallized one or more cannabinoids by dissolving in ethanol, methanol, isopropylic alcohol or acetone, filtering, evaporating to dryness and recrystallizing using the same non-polar solvent as in step a), thereby resulting in the purification of one or more cannabinoids.
