Apparatuses, methods, and systems for extraction, isolation and conversion of various cannabinoids, and modifications of whole-plant hemp extracts therewith
Apparatuses, methods, and systems for extraction, isolation, purification, and conversion of various cannabinoids, and modifications of whole-plant hemp extracts therewith are presented. A method for preparing a whole-plant hemp extract based product includes extracting cannabinoids from plant materials, such as one or more hemp varieties of Cannabis sativa. The method also includes separating and purifying CBD from the extracted cannabinoids, converting purified CBD to Δ9-THC and Δ8-THC and concurrently converting Δ9-THC to CBN, purifying and separating the CBN, and combining the purified CBN with a whole-plan hemp extract. Products and supplements related to the method are also described.

Solvents, methods, and systems for isolating botanical extracts from plants
The present invention provides improved solvents, methods, and systems for isolating purified cannabinoids from various sources. It has been found that C.sub.9 to C.sub.11 non-aromatic hydrocarbon solvents, and especially n-decane, work surprisingly well for crystallization of cannabinoids such as cannabidiol. Some variations provide a method of isolating cannabinoids from a cannabinoid-containing solution, comprising contacting the solution with a C.sub.9-C.sub.11 non-aromatic hydrocarbon solvent (e.g., n-decane) at a first temperature, to generate a mixture; cooling the mixture to precipitate cannabinoids; and isolating the precipitated cannabinoids. Other variations provide a method of isolating cannabinoids from a cannabinoid-containing solution, comprising contacting the solution with a C.sub.9-C.sub.11 non-aromatic hydrocarbon solvent (e.g., n-decane) at a first temperature below the solvent boiling point, to generate a mixture; subjecting the mixture to a second temperature that causes vaporization of the solvent, to precipitate at least some of the cannabinoids; and isolating the precipitated cannabinoids.
