Hydrogenation of cannabis oil
View Patent ↗The present invention relates to the extraction and hydrogenation of essential oil of a cannabis plant. The invention includes hydrogenated cannabis compounds and compositions, as well as methods of preparation and therapeutic uses for regressing tumors in a cancer patient. The extract can include 9-tetrahydrocannabinoic acid and 9-cannabidiolic acid, and the hydrogenated cannabis oil can include hydrogenated 9-tetrahydrocannabinoic acid, hydrogenated 9-cannabidioc acid and, mixtures and blends thereof.
1. A method of hydrogenating cannabis oil, consisting essentially of:
obtaining cannabis which contains at least one of 9-tetrahydrocannabinoic acid and 9-cannabidioc acid;
extracting an essential oil from the cannabis to form an essential oil extract; and
hydrogenating the essential oil extract to form hydrogenated cannabis oil which contains at least one of hydrogenated 9-tetrahydrocannabinoic acid and 9-cannabidioc acid, wherein the hydrogenation is performed with a component selected from the group consisting of silica, alumina, titania, calcium carbonate and barium sulfate.
2. The method of claim 1 , wherein a method for the extracting is selected from the group consisting of steam distillation, organic solvent extraction, super critical fluid extraction and cryo-mechanical extraction.
3. The method of claim 1 , wherein the extracting is conducted in the presence of a solvent.
4. The method of claim 1 , wherein the extracting is not performed with a solvent.
5. The method of claim 3 , wherein the solvent is selected from the group consisting of butane, propane and mixtures thereof.
6. The method of claim 3 , wherein the extracting is conducted absent of heat.
7. The method of claim 1 , wherein the extracting further consists essentially of de-fatting the essential oil extract.
8. The method of claim 1 , wherein the de-fatting is winterization.
9. The method of claim 1 , wherein the hydrogenating is conducted at a temperature from about 25° C. to 250° C.
10. The method of claim 1 , wherein the hydrogenating is conducted at a hydrogen pressure from about 0.1 to about 20 mPa.
11. The method of claim 1 , wherein the hydrogenating is conducted on the essential oil extract, which is free of extraction solvent.
12. The method of claim 1 , wherein the hydrogenating is conducted on the essential oil extract.
13. The method of claim 1 , wherein said hydrogenated cannabis is separated out.
