Abstract

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.

Claims (18)

1. A sealed container device comprising a composition comprising:

a. a first cannabinoid, wherein said first cannabinoid is cannabinol;

b. a second cannabinoid, wherein said second cannabinoid is cannabidiol; and

c. a third cannabinoid, wherein said third cannabinoid is Δ9-tetrahydrocannabinol;

wherein the composition has a cannabinol:cannabidiol ratio between 1:1 and 1:5 by weight and wherein the composition comprises no more than 5% Δ9-tetrahydrocannabinol by weight of the composition, and wherein the cannabinoids are isolated, purified or synthetic.

2. The sealed container device of claim 1 , wherein the first and second cannabinoid are at a combined concentration of at least 10 mg/g of the composition.

3. The sealed container device of claim 1 , wherein the cannabinol:cannabidiol ratio is between 1:1 and 1:2 by weight.

4. The sealed container device of claim 1 , wherein the cannabinol:cannabidiol ratio is about 1:1 by weight.

5. The sealed container device of claim 1 , wherein the first, second, and third cannabinoid are at a combined concentration of at least 10 mg/g of the composition.

6. The sealed container device of claim 1 , wherein the Δ9-tetrahydrocannabinol is no more than 4% of the composition by weight.

7. The sealed container device of claim 1 , wherein the Δ9-tetrahydrocannabinol is no more than 3% of the composition by weight.

8. The sealed container device of claim 1 , wherein the Δ9-tetrahydrocannabinol is no more than 2% of the composition by weight.

9. The sealed container device of claim 8 , wherein the first, second, and third cannabinoid are at a combined concentration of at least 10 mg/g of the composition.

10. The sealed container device of claim 1 , wherein the cannabidiol is at a concentration of at least 50 milligrams of cannabidiol per gram of the composition.

11. The sealed container device of claim 1 , wherein the cannabidiol is at a concentration of at least 10 mg/g of the composition.

12. The sealed container device of claim 1 , wherein the cannabinol is at a concentration of at least 10 mg/g of the composition.

13. The sealed container device of claim 1 , wherein the cannabinol is at a concentration of at least 2 mg/g of the composition.

14. The sealed container device of claim 1 , wherein the Δ9-tetrahydrocannabinol is no more than 1% of the composition by weight.
