Δ.sup.9-Tetrahydrocannabinol (Δ.sup.9-THC or THC) and cannabidiol (CBD) are major constituents of the Cannabis plant that have pharmacological properties with potential therapeutic value. This invention is directed to processes for large scale isolation of these two and other cannabinoids from the Cannabis sativa plant. This is accomplished through the discovery that protected amino acid esters of the cannabinoids are easier to separate using normal phase silica column chromatography. Mild base hydrolysis of the esters regenerates the free cannabinoids in a purified form. The invention is also applicable to the isolation of other cannabinoids from Cannabis extracts.

In alternative embodiments, provided are industrial processes and methods for extracting or removing cannabinoids, flavonoids and terpenes from plant materials such as trichomes. In alternative embodiments, the cannabinoids, flavonoids and terpenes are extracted or removed from the plant materials using a non-polar, organic solvent, or a mixture of non-polar, organic solvent and polar, organic solvent.

A method is provided for removing THC from raw cannabis oil.

A method of generating an oligosaccharide encapsulated cannabidiol (CBD) formulation includes forming a cannabidiol ethanol mixture comprising ethanol and cannabidiol, forming an oligosaccharide CBD slurry by mixing the oligosaccharide with the cannabidiol ethanol mixture. The slurry is heated and mixed in a pressurized chamber to form a colloidal mixture, which is distributed into a tray as a layer. A cover is added to the tray to form an evaporation vessel, which is heated in a heating chamber. A rapid cooling process is performed on the colloidal mixture layer by removing the cover and spraying pulverized dry ice on the layer. The rapid cooling process is repeated until crystal formation is detected within the layer, the crystals including oligosaccharide encapsulated cannabidiol. An oligosaccharide encapsulated cannabidiol formulation includes cannabidiol and at least one oligosaccharide in a ratio in the range between about 1000:1 to 2200:1 (w/w) of CBD.

Methods for extracting and concentrating cannabinoids using ultrasound-enhanced solvent extraction. Freshly harvested cannabis plant materials, which may be selectively chosen plant parts or the entire plant itself, are shredded to a particular particle size. The plant material is then mixed with a solvent to form a slurry, and thereafter subjected to ultrasound to release intracellular contents into the solvent. Filtering steps are then applied to remove biomass, waxes and chlorophyll. Water removal and solvent recovery steps are further applied to ultimately derive an extract having high concentrations of target cannabinoids, and in particular cannabidiol (CBD). The methods may be deployed on-site in batch or continuous flow processes, and may further be utilized to derive other types of materials from plants, such as essential oils.
