Methods to Reduce Chlorophyll Co-Extraction Through Extraction of Select Moieties Essential Oils and Aromatic Isolates

Abstract

A system machines and methods for extracting select moieties, flavonoids, and essential oils from plant material without co-extracting chlorophyll, lipids and other undesirable constituents from plants. Super-cooled extraction techniques are taught. Likewise, according to embodiments methods provides 100% grain ethyl alcohol extract with a concentration of chlorophyll that is below 1%.

What is claimed is: 
     
         1 . A composition that comprises the plant substrate extract product by a safer and more reliable extraction process, wherein the composition comprises an essential oil or a mineral oil, and wherein the process is for extracting cannabinoids and to reduce chlorophyll and wax co-extraction from a cannabis or hemp plant substrate comprising, wherein the process excludes use of liquid carbon dioxide in combination, and wherein the process comprises:
 (i) pre-processing comprising lowering the temperature of a solvent to a range of −30 degrees C. to −50 degrees C.   (ii) contacting at −30 degrees C. to −50 degrees C., wherein there is a contacting time between the cannabis plant substrate and the solvent to create an emulsion,   (iii) evaporating for reduction of the emulsion by means of atmospheric evaporation of the solvent,   (iv) recovering for recovery of the solvent from the emulsion,   (v) purging under vacuum to remove remaining solvent from the extract whereby a resultory extract is substantially free of any lipids and chlorophyll,
 wherein optionally, 
 (a) the solvent is 95% ethanol and 5% of a solvent that is another solvent that does not comprise ethanol, or 
 (b) the solvent is at least one solvent-like material selected from the group consisting essentially of heptane, hexane, isopropyl alcohol, and methanol. 
   
     
     
         2 . The composition of  claim 1 , wherein the composition is one of:
 (i) a liquid at room temperature (23 degrees C.),   (ii) a composition that comprises an oil, and wherein the oil is optionally an essential oil, a vegetable oil, or a mineral oil,   (iii) a composition that contains less than 5% by weight an oil, or that contains less than 5% by volume an oil, as determinable at room temperature.   
     
     
         3 . The composition of  claim 1 , wherein the composition comprises one or more of, acetic acid, acetone, acetonitrile, N,N-dimethylacetaide (DMA), N,N-dimethylformamide (DMF), 3-methyl-1-butanol, methyl-butyl-ketone (CH 3 (CH 2 ) 3 COCH 3 ), pentane, 1-pentanol, and 1-propanol. 
     
     
         4 . The composition of  claim 1 , wherein the composition comprises one or mote of, anisole, benzene, 1-butanol, 2-butanol, butylacetate, tert-butylmethylether, carbon tetrachloride, chlorobenzene, chloroform, cumene, and cyclohexane. 
     
     
         5 . The composition of  claim 1 , wherein the composition comprises one or more of, 2-propanol, pyridine, propylacetate, pyridine, sulfolane, tetrahydrofuran (THF), tetralin, toluene, 1,1,1-trichlorethane, 1,1,2-trichlorethene, triethylamine, and xylene. 
     
     
         6 . The composition of  claim 1 , wherein the composition comprises one or more of, 1,2-dichlorethane, 1,1-dichloroethene, 1,2-dichloroethene, 1,2-methoxyethane, dichloromethane, N,N-dimethylacetaide (DMA), N,N-dimethylformamide (DMF), and dimethylsulfoxide (DMSO). 
     
     
         7 . The composition of  claim 1 , wherein the composition comprises one or more of, 1,4-dioxane, 2-ethoxyethanol, ethylacetate, ethyleneglycol, ethylether, ethylformate, formamide, formic acid, heptane, hexane, isobutylacetate, isopropylacetate, methanol, 2-methoxyethanol, and methylacetate. 
     
     
         8 . The composition of  claim 1 , wherein the composition comprises one or more of, methylcyclohexane, methylethylketone, methylisobutylketone, 2-methyl-1-propanol, N-methyl-pyrrolidone, nitromethane, and nitromethane. 
     
     
         9 . The composition of  claim 1 , wherein the composition comprises one or more of, butane, hexane, cyclohexane, ethane, pentane, octane, diethyl ether, methanol, ethanol, isopropanol, n-propanol, chloroform, ethyl acetate, acetone, diethylamine, xylene, and dioxane.
