Claims

WHAT IS CLAIMED IS:

1 . A method of purifying secondary compounds from plant material, comprising:

adding the plant material to alcohol;

sonicating the alcohol and plant material;

dissolving secondary compounds in the alcohol to create a solution of secondary compounds;

physically separating the plant material from the solution comprising secondary compounds; and

evaporating the alcohol from the solution.

2. The method of claim 1 , comprising evaporating the alcohol from the solution at a pressure of less than 1 atmosphere.

3. The method of claim 1 , comprising sonicating the alcohol and plant material at a temperature of between about -80 to 30 degrees Celsius.

4. The method of claim 3, comprising sonicating the alcohol and plant material at a temperature of between about -50 to 10 degrees Celsius.

5. The method of claim 4, comprising sonicating the alcohol and plant material at a temperature of between about -30 to -10 degrees Celsius.

6. The method of claim 1 , comprising evaporating the alcohol from the solution at a temperature of between about 20 to 60 degrees Celsius.

7. The method of claim 1 , wherein the alcohol is chosen from methanol, ethanol, propanol, and butanol.

8. The method of claim 7, wherein the alcohol is ethanol.

9. The method of claim 1 , comprising collecting a precipitated cannabinoid from within an alcoholic solution of secondary compounds.

10. The method of claim 9, comprising dissolving the precipitated cannabinoid in an alcohol, creating a second solution, then recrystallizing the precipitated cannabinoid from the second solution.

1 1 . The method of claim 10, comprising evaporating alcohol from the second solution.

12. The method of claim 10, wherein the alcohol is ethanol.

13. A product produced by the method of claim 9.

14. The product of claim 13, wherein the said product comprises single crystals of a cannabinoid.

15. The product of claim 14, wherein the said single crystals of a cannabinoid are suitable for x-ray diffraction.

16. A composition comprising the product of claim 13.

17. A device comprising the product of claim 13, attached to a rigid support means. 18. The device of claim 17, comprising a rigid transparent vessel;

wherein said product is contained within said rigid transparent vessel; and wherein said rigid support means is contained within said rigid transparent vessel. 19. The device of claim 17, comprising between 0.1 to 1 .0 grams of the said product.
