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.
1. A method for preparing a cannabis extract enriched in cannabinol, said method comprising:
(a) providing purified cannabidiol;
(b) converting the purified cannabidiol to delta 9 tetrahydrocannabinol and delta 8 tetrahydrocannabinol, and concurrently converting the delta 9 tetrahydrocannabinol to cannabinol by heating the purified cannabidiol at 100° C. to 180° C. for at least 24 hours, thereby producing cannabinol; and
(c) combining the cannabinol produced from step (b) with a cannabis extract, thereby producing the cannabis extract enriched in cannabinol.
2. The method of claim 1 , wherein the cannabis extract enriched in cannabinol also comprises a cannabinoid selected from the group consisting of cannabidiol, cannabichromene, cannabigerol and cannabidivarin.
3. The method of claim 1 , wherein the cannabis extract enriched in cannabinol also comprises cannabidiol.
4. The method of claim 1 , wherein the cannabis extract is from one or more hemp varieties of Cannabis sativa.
5. The method of claim 1 , wherein the purified cannabidiol is greater than 99% w/w cannabidiol.
6. The method of claim 1 , wherein the purified cannabidiol comprises cannabidiol crystals.
7. The method of claim 3 , wherein the cannabis extract enriched in cannabinol has a cannabinol:cannabidiol w:w ratio between 20:1 to 1:20.
8. The method of claim 3 , wherein the cannabis extract enriched in cannabinol has a cannabinol:cannabidiol w:w ratio between 2:1 to 1:2.
9. The method of claim 3 , wherein the cannabis extract enriched in cannabinol has a cannabinol:cannabidiol w:w ratio of 1:1.
10. The method of claim 1 , wherein the cannabis extract enriched in cannabinol comprises delta 9 tetrahydrocannabinol.
11. The method of claim 10 , wherein the cannabis extract enriched in cannabinol comprises cannabidiol and has a cannabidiol:delta 9 tetrahydrocannabinol w:w ratio between 20:1 to 500:1.
12. The method of claim 10 , wherein the cannabis extract enriched in cannabinol comprises less than 1% by weight of delta 9 tetrahydrocannabinol.
13. The method of claim 10 , wherein the cannabis extract enriched in cannabinol comprises less than 0.5% by weight of delta 9 tetrahydrocannabinol.
14. The method of claim 10 , wherein the cannabis extract enriched in cannabinol comprises less than 0.3% by weight of delta 9 tetrahydrocannabinol.
15. The method of claim 1 , wherein the purified cannabidiol that is converted in step (b) is not dissolved in an acid.
16. The method of claim 15 , wherein the cannabis extract enriched in cannabinol also comprises cannabidiol.
17. The method of claim 16 , wherein the cannabis extract enriched in cannabinol has a cannabinol:cannabidiol w:w ratio between 20:1 to 1:20.
18. The method of claim 16 , wherein the cannabis extract enriched in cannabinol has a cannabinol:cannabidiol w:w ratio between 2:1 to 1:2.
