Photocatalysis extraction method for enriching cannabidiol from the wild hemps

A method for producing cannabidiol oil of high quality and purity using photocatalysis comprising the steps of:

• (A) preparing ground wild hemp from wild hemp plants, wherein flowers and stems of wild hemp plants are ground to small fragments;
• (B) immersing the ground wild hemp into an organic solvent to form a wild hemp solution, wherein the wild hemp solution is placed in a sealed container under high frequency ultrasound for a predetermined period of time;
• (C) dewaxing the wild hemp with a photocatalyst, wherein the photocatalyst is added to the wild hemp solution in the container, and wherein the wild hemp solution with the photocatalyst is kept at a temperature between −75° C. to 65° C. for a predetermined number of hours under a constant ultraviolet (UV) radiation;
• (D) distilling the wild hemp solution in the container to obtain a CBD (cannabidiol) oil, wherein the distillation is performed under a vacuum pressure and at a room temperature of 10° C. to 30° C.;
• and
• (E) recrystallizing the distilled CBD oil obtained, wherein the CBD oil is placed inside a recrystallization reactor at a temperature between −10° C. to −1° C. for about 6 to 24 hours.

A method for producing cannabidiol oil of high quality and purity using photocatalysis comprising the steps of:

• (A) preparing ground wild hemp from wild hemp plants, wherein flowers and stems of wild hemp plants are ground to small fragments;
• (B) curing the ground wild hemp in a high temperature device, wherein the ground wild hemp is decarboxylated for about one to six hours at a temperature between 100° C. to 290° C.;
• (C) immersing the cured ground wild hemp into an organic solvent to form a wild hemp solution, wherein the wild hemp solution is placed in a sealed container under high frequency ultrasound for a predetermined period of time;
• (D) dewaxing the wild hemp in the wild hemp solution with a photocatalyst, wherein the photocatalyst is added to the wild hemp solution in the container, and wherein the wild hemp solution with the photocatalyst is kept at a temperature between −75° C. to 65° C. for a predetermined number of hours under a constant ultraviolet (UV) radiation;
• (E) distilling the wild hemp solution in the container to obtain a CBD (cannabidiol) oil, wherein the distillation is performed under a vacuum pressure and at a room temperature of 10° C. to 30° C.;
• and
• (F) recrystallizing the distilled CBD oil obtained, wherein the CBD oil is placed inside a recrystallization reactor at a temperature between −10° C. to −1° C. for about 6 to 24 hours.
