The following examples are provided for illustrative purposes only and are not intended to limit the scope of the invention. 6, 2015, and the disclosure is hereby incorporated by reference herein in its entirety. Moreover, the use of the term including, as well as other forms, such as includes and included, should be considered non-exclusive. It is also known as -linalool, linalyl alcohol, linaloyl oxide, p-linalool, allo-ocimenol, and 3,7-dimethyl-1,6-octadien-3-ol. CBD can occur in up to 40% of the cannabinoid extracts from cannabis. Optionally, the crystallization may be performed under pressure or vacuum. THCA is one type of chemical present in the cannabis plant. By using pressure, motion, and heat, the solvent is evaporated, leaving behind 9 tetrahydrocannabinolic acid. The crystalline substance being isolated in this technique is THCA (with the carboxylic acid still attached). When exposed to heat, non-intoxicating THCA converts to intoxicating THC and produces that classic cannabis high. 3.6A: Single Solvent Crystallization. When the temperature is dropped either quickly or by a large amount, there is a much stronger drive towards crystallization, and Nucleation becomes much more important in the formation of crystals, leading to many small crystals being formed. Table 1 Data-collection and reduction statistics. It is also an inflammation and pain inhibitor and has been successful for treating migraines and stimulating bone growth. It is also known as 4-isopropenyl-1-methylcyclohexenep-Menth-1,8-dieneRacemic: DL-limonene; dipentene. To make THCA crystalline, you start with a cannabis extract. Alternatively, the method includes crystallizing the THCa directly from the solvent extract, particularly where the plant (or plant parts) comprise a high percentage of cannabinoids and/or THCa. [1] The basic idea of this product probably came as a result of the technique for making shatter or other full spectrum extracts; it essentially uses the same appliances and materials, but the extract is instead subjected to different conditions to induce crystallization, and we will talk about what those conditions are below. Then it will go trough filter again and put back in the rotary evaporator to the methonal from your THCA extract. THCa is a known anti-inflammatory and provides many of the same benefits of THC but without psychotropic side effects. Suitable for crystallization, winterization and decarboxylation of extracts, CORPORATE HEADQUARTERS: The scope of the present invention is limited only by the scope of the following claims. Besides simply smoking THCA crystals and/or mixing with flower, formulation specialists may want to combine these diamonds with terpenes or other cannabinoids to create a unique treatment for medical cannabis patients. Some people prefer the flavorless nature of this product, while others take steps to reincorporate that traditional cannabis flavor. If you fail to decarb your weed, you're doing little more than adding raw plant matter. THCa Crystalline was developed as a means of delivering large, quantifiable doses of THCa and is known as the purest isolate anywhere on the market - testing at 99-100%. Which morphology dominates seems to be influenced by the process conditions and the quality of the starting material. Methods to increase surface area for crystallization are known in the art, such as glass beads, which are optionally added prior to the crystallization. The extract was collected in a beaker and placed on dry ice in a cooler. When growing crystals, there are two concurrent processes that are kept in balance. Two isolation procedures for 9-tetrahydrocannabinolic acid A (THCA), the biogenetic precursor in the biosynthesis of the psychoactive 9-tetrahydrocannabinol (THC) in the cannabis plant, are presented. Its IUPAC name is 3,7-dimethylocta-1,6-dien-3-ol. When the process is complete, crystal looks like, well, small crystals. Pinene is found in conifer, pine and orange. THCA crystalline can be incorporated into food using a carrier oil, such as olive oil or coconut oil. Sulak's article indicates that higher doses of THCA did not generally improve the response, with one patient getting worse after increasing the dose of THCA. Support: support@precisionextraction.com. Limonene is a chiral molecule. Two morphologies of crystals were observed, sheet and ball crystals. The present invention also includes removing a precipitate from the cooled solvent extract. Cannabinoids may also occur as their pharmaceutically acceptable salts. Also, terms such as element or component encompass both elements and components comprising one unit and elements and components that comprise more than one unit, unless specifically stated otherwise. There are several different ways to go about extracting isolates, which utilize chemical processes and a myriad of other techniques.

For those who need a high concentration, this is a great option to get the most for your money. Gums include complex polysaccharides. Alternatively methods for cooling the solvent extract filtrate may also be used, such as storing in a cold environment such as in a refrigerator or freezer, or by use of liquid nitrogen. THCA crystalline is an isolated product, meaning as long as you take the same dose you should get a reasonably consistent experience. Fractional distillation, immiscible liquid-liquid separation, or preparative and flash chromatography have been employed individually or in combination to separate desirable components of plant extracts from less desirable counterparts in other pharmaceutical plant preparations and natural products like essential oils. Methods for Obtaining Purified Cannabis Extracts and THCA Crystals. 9. The advantage of using them lies in their near 100 percent THC content. Most of the terpenes in THCA crystalline are removed and the resulting product has little aroma with potent effects if heated up. This method encompasses directly crystallizing THCa from the solvent extract, by performing a solvent extraction of the plant or specific plant parts in accordance with the methods of the invention. The balance of the THC and THCa remained in the solvent with the rest of the plant extract residual filtrate which is enriched in cannabinoids and terpenes relative to the original plant extract. THCA crystalline is one of the most complicated forms of cannabis to make, but the final product is one that is coveted by many for its extremely high THCA content. Lignin is commonly understood as a complex polymer of aromatic alcohols and is a component of the cell walls of plants. 2. this bud has little things that look like crystals. Therefore, improved methods for removing plant material such as lignin, lignans, gums and lecithins from cannabis oil, and improved methods for obtaining purified THC or THCa, are desired in the art. For example, the butane can be evaporated from filtrate and the extract gently heated in a desiccator or vacuum oven to convert any THCa to THC. Two flash chromatography systems that can be used independently from each other were developed to The cooler is optionally between about 40 C. and 70 C. In one embodiment, the temperature is about 75 C. The temperature can be varied during the process, and is optionally carried out at an average temperature of less than about 10 C., less than about 0 C., less than about 10 C., less than 20 C., less than about 30 C., less than about 40 C., less than about 50 C., less than about 60 C., less than about 70 C., or less than about 80 C. In another embodiment, the temperature at which the cooling takes place is between about 50 C. and about 85 C. The cooling step may take place for between about one hour and one week, between about 10 hours and about four days, between about one day and about three days. The next part of the process utilizes machinery, such as a rotary vessel or reactionary vessel. Optionally, the cannabis supernatant can be cooled another time to yield a precipitate of high purity THCa crystals and a residual filtrate enriched in other cannabinoids and terpenes. Recent studies suggest that CBN can be administered as an antidepressant, can be used to prevent convulsions and to sedate patients experiencing pain. A plant that comprises at least one cannabinoid includes. This pure THCa converts to THC when vaped and creates a clear and highly cerebral effect, or remains non-psychoactive . The present invention includes a method for obtaining a higher purity cannabinoid solvent extract from a plant which comprises cannabinoids and/or terpenes. CBC has been shown to inhibit the growth of cancerous tumors due to its interaction with anadamide, a human endocannabinoid. THCA crystalline is a newer, extremely potent extract on the market. Surprisingly, it is possible to remove the undesirable extractives by sedimentation and removal of said impurities promotes the crystallization of THCa, when it is present. Terpenes are naturally present in cannabis; however, they can be removed during the extraction process. The mother liquor can be subjected to another cooling step to test if crystals will continue to form. The Two-Way Relationship Between Cannabis and its Dibble, Clare J. and Cole, Isaac B. What we mean here is a form of marijuana extraction product, a cannabis isolate. The initial sediment (precipitate after the first precipitation step) includes the molecules that contribute to the dark color of certain extracts and those that carbonize and leave residual solids during vaporization of a sample. When growing crystals, there are two concurrent processes that are kept in balance. . This method may further optionally include the step of crystallizing the THCa from the solvent extract filtrate. Interested in learning how to optimize your THCa crystallization techniques? The resultant oil, or cannabis resin, is a dark brown, viscous and sticky oil and generally contains up to about 75% of THC (or THCa), depending on the extraction conditions. -Pinene is a major constituent in turpentine. Pure THC crystals are one of the newest and most exciting trends in extraction technology. The extraction was repeated two times and the extracts were combined prior to the separation step. To achieve their desired taste preferences, many people combine THCA crystalline with terpenes. Here's how they do it. It also helps reduce nausea, suppress muscle spasms, relieve pain, and stimulate appetite. These techniques are for you to further explore and expand your understanding of forming THCA diamonds. Figure 3.1: Various crystals. That being said, if the product is heated, it becomes THC (not THCA), and it will give you a high. These tiny crystals that blanket the surface of the flower produce the cannabinoids, terpenes, and flavonoids which are responsible for the unique smell and taste of each strain. In one embodiment, the crystallization step is encouraged and/or enhanced by increasing surface area. This is the story of delta 10-tetrahydrocannabinol (10-THC) and its mysterious formation and crystallization following distillation. AKA THC crystals or THC diamonds are a marijuana concentrate that is in a solid form. Low pressure and heat are applied so that the target compound crashes out of solution, or precipitates out as a solid. See also. CBD generally occurs in the cannabis plant prior to processing as CBDa which has a carboxylic acid at R, CBD and CBDa have been shown effective in treating inflammation, diabetes, cancer, mood disorders (PTSD to ADD) and neurodegenerative diseases such as Alzheimer's. In another embodiment, the terpene/terpenoid includes myrcene. After two filterings, the solvent extracts were optically clear. Optionally hemp products or products from other plant extracts would terminate this process here. The described examples are provided for illustrative purposes and are not intended to limit the scope of the invention. The process can be repeated several times and the total liquid from the multiple runs can be combined. ), with extracts making up the remaining 45%, and according to figures from Colorado, another beacon of legalisation in the US, the concentrate market is growing at an astounding rate, with sales increasing by 125% from 2015 to . The crystallization step is enhanced after the strong tasting, dark brown material (without being bound by theory, understood as high molecular weight lignin, lignans, gums, lignocellulosic material, and the like) has been removed, as described hereinabove, resulting in higher purity THCa. THCA slowly decarboxylates during storage and fermentation. 9.4.14.4 The Cotton Candy Extraction Technique; 9.5 Formulation and Application Expand child menu. To much pressure and nothing can gas off as the BP of your terps, cannabinoids, and gas gets to high. If vaporized, this filtrate leaves no residue or a light waxy white residue, but no carbonized black residuals. THCA is typically administered along with other components of cannabis in a tincture via an under-the-tongue dropper or spray. As one example of the process, dried cannabis material (bud, trim, or fan leaves), which is optionally milled (bowl trim, and/ or blended in a blender), is packed into an extraction column, for example, about 50 g plant matter is packed into a 1.5 inch diameter aluminum column 12 inches in length. Caryophyllene is known to be one of the compounds that contribute to the spiciness of black pepper. Remember that THCA becomes THC once its heated, so if you include this in food items that are exposed to heat, you will experience the psychoactive effects THC gives. Post chromatography, the crystals are dissolved in methanol and then filtered and then roto-vaped to remove the methanol. Winterizing will clean up your fats to give you a somewhat crystalline product at over 80% THCA. The end product itself has many benefits, especially for those looking to solely reap the benefits of THCA without any extra compounds present. Provisional Application Ser. Engineers have devised an extraction method that creates an extract that 99.96% pure. Cannabis terp sauce and diamonds are often sold together to add flavor and aroma to the product. While the end result is virtually the same, trace elements of the solvents used to separate the THC from the "goop-of-cannabinoids" could be present. Its IUPAC name is 6,6-dimethyl-2-methylenebicyclo[3.1.1]heptane and is also known as 2(10)-Pinene; Nopinene; Pseudopinene. Alternatively, the cooling step may take place for longer than 10 minutes, longer than 30 minutes, longer than about an hour, longer than about two hours, longer than about three hours, longer than about four hours, longer than about six hours, longer than about eight hours, longer than about 12 hours, longer than about 18 hours, or about twenty four hours or longer. Nucleation determines how quickly new crystal seeds are formed in the container. To discard the impurities represents a loss of 10% of the total extracted THCa or less. Glass beads were added to the beaker before putting it into an undisturbed deep freeze (75 C.). In the cooling step, the temperature of the solvent extract or co-solvents should be maintained in such a way that the mixture is chilled but the solvent remains fluid, allowing impurities to condense and settle to the bottom of the container. c) removing the precipitate from the cooled solvent extract to yield a solvent extract filtrate; d) allowing THCa to crystallize from the solvent extract filtrate; and, Methods for Obtaining Purified Cannabis Extracts and THCA Crystals, Application filed by Clare J. Dibble, Isaac B.

The retentate turned brown upon the solvent evaporation, is believed to be lignin, lecithin, and/ or other undesirable, high molecular weight materials that were extracted by the solvent. WiLLBiLLy, inventor of the notorious blue sapphire THCa crystals and founder of WiLLBiLLy Productions, joins us to discuss specific SOPs for hydrocarbon extraction and the finishing techniques that it takes to create all the various craft concentrates this extraction style can produce. The Benefit of Rosin for THCa . Your extract will come out as an off yellow powder. The description of the various embodiments has been presented for purposes of illustration and description, but is not intended to be exhaustive or limiting of the invention to the form disclosed. If THCa is present in the initial filtrate, chilling the initial filtrate a second time after removing the initial sediment results in precipitated THCa and a residual filtrate relatively lower in THC and replete with any other cannabinoids or terpenes present in the original plant extract. Others choose to dab the product in order to experience a high, while some consume it in powder form in pill capsules for easy ingestion. TetrahydrocannabivarinTHCV is structurally similar to THC, but acts an antagonist to the CB1 & CB2 receptors in the body. In one example of the crystallization step, a container (such as a beaker) containing the solvent extract filtrate is allowed to sit in a cooler containing dry ice for between about 12 hours and several days. In one embodiment, the solvent extract filtrate is cooled to allow for crystallization of the THCa. When THCA is heated up past approximately 220 degrees Fahrenheit, it is converted to THC. Wait until the solution reaches 45 C and all the oil has dissolved. Alternatively methods for cooling the solvent extract may also be used, such as storing in a cold environment such as in a refrigerator or freezer, or by use of liquid nitrogen. The crystals were harvested by filtering solvent and extract and capturing the retentate as well as removing crystals by scraping them from the glass beads through a sieve with a metal spatula. These higher weight impurities can comprise, for example, such materials common to plants such as lignin, lignans, pigments, gums, lignocellulosic material, and lecithin. Cannabis Diamonds Are Non-Intoxicating. The present invention is directed toward overcoming one or more of the problems discussed above. Crystallization of THC-A with acetone This tek is to explore other possible routes of isolation of carboxylic THC, using acetone, instead of a traditional non-polar solvent like butane, hexane, pentane, etc. including but not limited to those related to solvent storage and fire marshal approval. The residual filtrate was found to contain cannabinoids and terpenes extracted from the original bud or trim, and THC and THCa that did not crystallize during the course of the run. In addition, because the end product has not been decarboxylated, it will not give you a high as long as it is not heated. . How are the Diamonds Made? It would be preferable to have purified forms of certain cannabinoids. Delta1-Tetrahydrocannabinolic acid (THCA) synthase is a novel oxidoreductase that catalyzes the biosynthesis of the psychoactive compound THCA in Cannabis sativa (Mexican . Crystallization should optionally be terminated before or when extracted oils begin to condense and foul the pure THCa. Many modifications and variations will be apparent to those of ordinary skill in the art. A cannabinoid useful for the present invention also includes cannabinol (CBN). A cannabinol useful for the present invention also includes tetrahydrocannabivarin (THCv) having a propyl side chain. Crystallization is a widely used technique in solid-liquid separation processes. Optionally, any product should have solvent thoroughly removed. All references cited herein are incorporated in their entirety by reference. It's the main reason why smoking a doobie gets you so high. In the cooling step, the temperature of the solvent extract filtrate should be maintained in such a way that the mixture is chilled but the solvent remains fluid, allowing THCa to crystallize and settle to the bottom of the container.
