Abstract

This invention relates to the extraction of psychoactive compounds from organisms for use in medicine. Extraction is carried out with a strong acid or strong base to either promote or inhibit dephosphorylation. The extract in the slurry form is standardized with added excipient so that when it is dried the powdered composition has a specified total psychoactive alkaloid concentration, with a known ratio of phosphorylated to dephosphorylated psychoactive alkaloids.

Claims (24)

1. A method for generating a phosphorylated psychoactive alkaloid extract comprising 0.1% to 99% by weight of a psychoactive alkaloid from a psychoactive organism, the method comprising:

a. providing a biomass of the psychoactive organism;

b. contacting the biomass with a solvent having a pH of greater than 7, wherein the psychoactive alkaloid comprises greater than 50% of a phosphorylated psychoactive alkaloid, wherein the solvent is a mixture of an alcohol, water, and a base;

c. removing the biomass from the solvent; and

d. evaporating the solvent after removing the biomass to yield the phosphorylated psychoactive alkaloid extract comprising 0.1% to 99% by weight of the psychoactive alkaloid.

2. The method of claim 1 , wherein, following (b), the biomass is contacted with a second solvent.

3. The method of claim 1 , wherein the alcohol comprises 60% to 99% of the mixture.

4. The method of claim 3 , wherein the alcohol is a C1-C4 primary aliphatic alcohol.

5. The method of claim 4 , wherein the C1-C4 primary aliphatic alcohol is ethanol or methanol.

6. The method of claim 1 , wherein the psychoactive organism is Psilocybe cyanescens, Psilocybe cubensis, Amanita muscaria , or any selection thereof.

7. The method of claim 1 , wherein the phosphorylated psychoactive alkaloid is psilocybin, baeocystin, norbaeocystin, aeruginascin, or any combination thereof.

8. The method of claim 1 , wherein the solvent is present in an amount of 10 milliliters (mL) to 100 mL.

9. The method of claim 1 , wherein the solvent has a pH of 9 or more.

10. The method of claim 1 , wherein the solvent has a pH of 10 or more.

11. The method of claim 1 , wherein the solvent has a pH of 10.5 to 13.5.

12. The method of claim 1 , wherein the solvent has a pH of 11 to 12.

13. The method of claim 1 , wherein the solvent has a pH of 13.

14. The method of claim 1 , wherein the psychoactive alkaloid is entirely the phosphorylated psychoactive alkaloid.

15. The method of claim 1 , wherein:

the psychoactive organism comprises phosphorylatable psychoactive alkaloid and non-phosphorylatable psychoactive alkaloid; and

the psychoactive alkaloid in the extract comprises the phosphorylatable psychoactive alkaloid and the non-phosphorylatable psychoactive alkaloid.

16. The method of claim 15 , wherein the phosphorylatable psychoactive alkaloid is 100% phosphorylated.

17. The method of claim 1 , wherein the pH of the solvent is greater than 10.5 and a maximum concentration of the phosphorylated psychoactive alkaloid in the extract is limited by an amount of dephosphorylated psychoactive alkaloid in the biomass.

18. The method of claim 1 , comprising, between (c) and (d), adjusting the pH of the solvent to a pH ranging from 3.5 to 4.5.
