Cannabis oil extracts and compositions

Abstract

The present invention provides cannabis oil extracts and compositions thereof, including cannabis oil compositions containing vitamin E, and methods for preparing the extracts and compositions. In some embodiments, the present invention provides a method for preparing a cannabis oil extract comprising eluting cannabinoids from cannabis plant material with a solvent to produce an eluate, filtering the eluate with a filter to produce a filtrate, evaporating the solvent from the filtrate with a distiller to produce a distillate, and purging the distillate under conditions sufficient to remove residual solvent, thereby preparing the extract. In some embodiments, the method further includes mixing a quantity of vitamin E with the extract to produce a cannabis oil composition.

1 . A method for preparing a cannabis oil extract, the method comprising:
 eluting cannabinoids from cannabis plant material with a solvent to produce an eluate;   filtering the eluate with a filter to produce a filtrate;   evaporating the solvent from the filtrate with a distiller to produce a distillate; and   purging the distillate under conditions sufficient to remove residual solvent, thereby preparing the extract.   
     
     
         2 . The method of  claim 1 , further comprising mixing a quantity of one or more ingredients selected from the group consisting of vitamin E, an essential oil, an herbal extract, a probiotic, a homeopathic remedy, a flower essence, and a carrier oil with the extract to produce a cannabis oil composition.

         7 . (canceled) 
     
     
         8 . The method of  claim 1 , wherein the cannabis plant material consists essentially of cannabis buds. 
     
     
         9 . The method of  claim 1 , further comprising solarizing the eluate before filtering the eluate. 
     
     
         10 . The method of  claim 1 , wherein the solvent is ethanol. 
     
     
         11 . The method of  claim 1 , further comprising freezing the cannabis plant material and the solvent before eluting the cannabinoids from the cannabis plant material with the solvent. 
     
     
         12 . The method of  claim 1 , wherein the cannabis plant material is a strain selected from the group consisting of a  Cannabis indica  strain, a  Cannabis sativa , a hybrid strain, a high-CBD strain, and a high-THC strain. 
     
     
         13 . The method of  claim 12 , wherein the strain is selected from the group consisting of AC/DC, Blueberry, Cannatonic, Medihaze, Afghan Goo, and Prize Kush. 
     
     
         14 . The method of  claim 1 , wherein purging the distillate under conditions sufficient to remove residual solvent comprises dehydrating the distillate with a dehydrator. 
     
     
         15 . The method of  claim 14 , wherein dehydrating the distillate includes dehydrating for at least about 72 hours. 
     
     
         16 . The method of  claim 1 , further comprising heating the distillate to form a decarboxylated distillate. 
     
     
         17 . The method of  claim 16 , further comprising purging the decarboxylated distillate under conditions sufficient to remove residual solvent, thereby forming the extract. 
     
     
         18 . The method of  claim 16 , further comprising filtering the decarboxylated distillate to form a decarboxylated filtrate. 
     
     
         19 . The method of  claim 18 , further comprising purging the decarboxylated filtrate under conditions to remove residual solvent, thereby forming the extract.
