An exemplary cannabichromene (CBC) is shown below: CBC, like THC and CBD, results from CBCa. In one embodiment, the crystallization step is encouraged and/or enhanced by increasing surface area. During chromatography, more chemicals are added to the mix to remove any unwanted compounds, and then the solution is once again put through the rotary or reactionary vessel to separate the THCA from the unwanted solvents and compounds. 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. You will most likely find higher levels of THCA in fresh flowers and from the living plant itself. Terpenes are a diverse group of organic hydrocarbons derived from 5-carbon isoprene units and are produced by a wide variety of plants. The methods of the present invention are also optionally useful to obtain a higher purity of terpene(s). The crystallization model described in 2 . As an example of the removal step, after precipitate has formed (on the bottom of the beaker in this example), the solvent extract is filtered through a vacuum assisted Buchner funnel using 12.5 cm diameter 101 fast filter paper and coffee filter and, if possible, taking care not to disturb the cake on the bottom of the beaker. THCA crystals (or THCA crystallines) are a powerful cannabis extract because of the high cannabinoid concentration, whether you use it as it is or smoke it as THC to obtain the psychoactive effects. A cannabinoid useful for the present invention also includes cannabinol (CBN). 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. Therefore, in one embodiment, the cannabis is dried. It's the main reason why smoking a doobie gets you so high. Visits to all company locations by advance appointment, please call. The filtrate was returned to a clean beaker and put back in the cooler on top of the dry ice for 3 hours and filtered again in a Buchner funnel with a coffee filter and slow quantitative filter. Applying those techniques to full spectrum extracts, or Live Resin, is the key to learning how to crystallize THC-A, or its decarboxylated and activated derivative, THC. The present invention is directed toward overcoming one or more of the problems discussed above. Wash using a pipette: used for small amount of crystals to be washed. Optionally, sedimentation (precipitation) can be repeated until the filtrate is optically clear. Which morphology dominates seems to be influenced by the process conditions and the quality of the starting material. The products made by the processes of the instant invention may be incorporated into any product or formulation, such as, for example, those products or formulations that are typically known to incorporate a cannabinoid. A cannabinol useful for the present invention also includes tetrahydrocannabivarin (THCv) having a propyl side chain. this bud has little things that look like crystals. The Growth factor dominates Nucleation in the equilibrium that exists between the two, and the conditions favor the formation of few, but large, crystals. 9.4.14.4 The Cotton Candy Extraction Technique; 9.5 Formulation and Application Expand child menu. All percentages and amounts in the present application, if not otherwise defined, are to be defined as weight percents (w/w). THCA is THC acid, the precursor to THC, the most abundant and intoxicating cannabinoid found in cannabis. 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. Gums include complex polysaccharides. Its widely regarded as the most potent form of marijuana, as it contains ~99.96% THCA. The balance of the cannabis resin generally contains other cannabinoids, terpenoids and a significant amount of other materials that originated in the plant that are not known to have therapeutic value. THCA crystalline is cannabis which has been refined until it is in the form of crystals. So basically you're seeing crystallization on a very small scale. That's fine, high terp oils tend to sugar. When exposed to heat, non-intoxicating THCA converts to intoxicating THC and produces that classic cannabis high. Five Facts You Need to Know About Cannabinoid Crystals. THCa crystals can power both the most radical dabs and the most approachable topicals. Crystallization is used in the chemistry laboratory as a purification technique for solids. Caryophyllene is known to be one of the compounds that contribute to the spiciness of black pepper. THCA (Tetrahydrocannabinol Acid) is the non-psychoactive precursor to THC. Bulk solids can be retained by a mesh screen, or any other known methods for filtration or separation between liquids and solids may be used. Exemplary cannabinoids useful for the present invention include cannabinols. For example, the beaker can be cooled another 1-3 hours and filtered again in a Buchner funnel with a coffee filter and slow quantitative filter. Following the cooling step, the precipitate is removed and a higher quality filtrate is obtained which contains higher levels of purity of cannabinoids and/or terpenes than the starting solvent extract. You can easily incorporate THCA crystals into a variety of food and drink, as it is flavorless. Is it possible for this process to cause a slight increase. Edit: THC is an oil; it is not crystalline. The developing crystals ideally form with high purity, while impurities remain in the . Values in parentheses are for the highest resolution shell. 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.

Racemic limonene is known as dipentene. Various modifications and additions can be made to the embodiments discussed without departing from the scope of the invention. No. The precipitate can be removed from the cooled solvent extract by any methods known in the art. It also helps reduce nausea, suppress muscle spasms, relieve pain, and stimulate appetite. The marijuana industry has grown exponentially in the past few decades. Biological sources produce one enantiomerthe principal industrial sourcecitrus fruit, contains D-limonene ((+)-limonene), which is the (R)-enantiomer (CAS number 5989-27-5, EINECS number 227-813-5). The scope of the present invention is limited only by the scope of the following claims. According to Mark of Covert Extracts to make mechanically separated THCA, "you need wax rosin in order to make mechanically separated THCA." From there, he says, "to separate the THCA from.

It is time to clear the smoke and demystify the hottest new cannabis concentrate on the market. Methods to increase surface area for crystallization are known in the art, such as glass beads, which are optionally added prior to the crystallization. Crystallization should optionally be terminated before or when extracted oils begin to condense and foul the pure THCa. 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. A plant that comprises at least one cannabinoid includes. Cannabinoids; Cannabidiol (CBD) Tetrahydrocannabinol (THC) Engineers have devised an extraction method that creates an extract that 99.96% pure. These steps include performing a solvent extraction of the plant to yield a solvent extract, cooling the solvent extract, removing the precipitate from the cooled solvent extract to yield a solvent extract filtrate; allowing THCa to crystallize from the solvent extract filtrate; and collecting the crystallized THCa. We have several different solutions based on your desired throughput capacity The invention also encompasses THCa obtained by the methods of the invention. 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. In one embodiment, the solvent extract is cooled to allow for precipitation of the higher molecular weight impurities. This step separates all those unwanted compounds from the THCA. 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. Optionally, the crystallization step may be repeated as many times as desired. Its IUPAC name is 3,7-dimethylocta-1,6-dien-3-ol. THCA diamonds are crystalline structures composed of pure THCA that result from a couple of different extraction methods, including "diamond mining" (more on that below) and the isolation of refined oil. CBC has been shown to inhibit the growth of cancerous tumors due to its interaction with anadamide, a human endocannabinoid. These factors can be thought of as putting a crystallization pressure on the dissolved compound, and they affect crystallizations by influencing whether Growth or Nucleation becomes the more important factor. As pressure increases in the jar, so does the BP of everything in the jar. 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. For those who need a high concentration, this is a great option to get the most for your money. Decarboxylation converts most of the acid into THC or CBD. Make sure the vessel condenser is cooled to -20 C. Convenient formulations include tablets, capsules, oils, gels, lozenges, troches, hard candies, nutritional bars, nutritional drinks, metered sprays, creams, suppositories, transdermal patches, among others. The residual filtrate may be combined with other materials and/or formed into products or formulations as described herein. 2. Regardless of how they are sold, diamonds will always be somewhat pure THCA products, whether they come with terp sauce or are sold alone as isolated THCA. That being said, if the product is heated, it becomes THC (not THCA), and it will give you a high. Isolates are nothing new. Regulatory compliance is always subject to local codes and regulations, 62/188,965 entitled Methods for Obtaining Purified Cannabis Extracts and THCA Crystals, filed Jul. 9-Tetrahydrocannabinolic acid A (THCA) is the most abundant compound of the cannabinoid fraction (presenting up to 95% of the cannabinoids in fresh, dried marihuana) of drug-type cannabis and the non-psychoactive biogenetic precursor of THC. In one example of the present invention, a container (such as a beaker) containing a butane solvent extract is allowed to sit directly on dry ice in a cooler for 1-4 hours. The RV 100 is for processing labs looking for a professional, durable solution for crystallization, winterization and decarboxylation. The residual filtrate can also be incorporated into finished products of their own, but retain some of the characteristics of the original material instead of being quality independent from the source materials, like the crystallized THCa. Pure THC crystals are one of the newest and most exciting trends in extraction technology. THCa is the non-activated, non-psychotropic acid form of THC. Methods for Obtaining Purified Cannabis Extracts and THCA Crystals. Lemon Voodoo Pheno. THCa is a known anti-inflammatory and provides many of the same benefits of THC but without psychotropic side effects. THCA and CBDA crystals can be heated through a variety of ways including vaporization, dabbing, or cooking. The trend of supersaturation generation during the process has a direct and significant role on crystal characteristics such as size, morphology, and purity. NOTICE OF APPEAL FILED, Free format text: These are referred to as extractives, referencing the relative ease with which they can be separated from the lignocellulose that composes the structure of the plant. Occasionally crystals will not form, even though the saturation point has been reached. THCa, the acid precursor to THC, was crystallized out of solution using the filtered solvent extract. The present inventor also found methods to crystallize THCa from, for example, extracted bud and higher-quality trim. The mother liquor can be subjected to another cooling step to test if crystals will continue to form. The driving force in crystal formation is supersaturation. Insert a pipette with square tip into the bottom of the test tube (rounded bottom), and remove the liquid, leaving the washed solids behind. The inventor has found that following the steps of the invention, 95+% pure THCa is readily crystallized from solution in quantities greater than 50% of the total extracted THCa. Unless otherwise indicated, all numbers used herein to express quantities, dimensions, and so forth used should be understood as being modified in all instances by the term about. In this application, the use of the singular includes the plural unless specifically stated otherwise, and use of the terms and and or means and/or unless otherwise indicated. Turn on stirring and turn on the heating bath and set to 45 C. The products made by the processes of the instant invention, e.g., crystallized THCa, solvent extract filtrate, or residual filtrate, for example, may be used in the acid form, or converted to the neutral forms by methods known in the art. 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. 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. In the case that relatively pure THCa is desired, the material may be retained in its acid form by processing fresh or recently dried materials, not exposing the material or extracts to heat or UV light, and/or maintaining any inert atmosphere that reducing the probability of oxidation reactions, as is known in the art. This pure THCa converts to THC when vaped and creates a clear and highly cerebral effect, or remains non-psychoactive . What is THCA Crystalline? Support: support@precisionextraction.com. Afterward, pentane is used to remove the smallest bits of non-THC or non-CBD material and then roto-vaped for the last time. THCA is the natural root form of THC. The present invention includes a method for obtaining a higher purity cannabinoid solvent extract from a plant which comprises cannabinoids and/or terpenes. -Myrcene is the name for the structural isomer 2-methyl-6-methylene-1,7-octadiene, which is not found in nature and is little used. Applying those techniques to full spectrum extracts, or Live Resin, is the key to learning how to crystallize THC-A, or its decarboxylated and activated derivative, THC. 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 addition, because the end product has not been decarboxylated, it will not give you a high as long as it is not heated. These steps are discussed hereinbelow. 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. Its important to note that these terpenes and cannabinoids produce the entourage effect, which means they contribute to the efficacy of the marijuana ingestion. The beaker containing the extract was allowed to sit directly on dry ice in a Pelican ProGear Elite Marine Deluxe Coolers cooler for 4 hours at approximately 70 C. Precipitate was observed on the bottom of the beaker. THCA crystals are incredibly potent. Concentrates especially have become increasingly popular over . Crystallization is a widely used technique in solid-liquid separation processes. If vaporized, this filtrate leaves no residue or a light waxy white residue, but no carbonized black residuals. The crystallization step can be performed by methods as known in the art. 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. Precipitation In one embodiment, the present invention includes a step of a solvent extraction of the plant which comprises cannabinoids. The following examples are provided for illustrative purposes only and are not intended to limit the scope of the invention. Alternatively, 80 to 200 g biomass containing cannabis is placed into a 2 inch diameter stainless steel column between 12 and 30 inches in length. 6, 2015, and the disclosure is hereby incorporated by reference herein in its entirety. Optionally, any product should have solvent thoroughly removed. And, because the product contains such a high concentration of THC, it will give you a powerful high in a small amount of product. In much of the chemical industry, recrystallization is used to achieve very high purity on a large scale without complex equipment. 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. An impure solid is completely dissolved in a minimal amount of hot, boiling solvent, and the hot solution is allowed to slowly cool. CBD and THCA diamonds are made by removing the crystalline structures from the runny terp sauce. THCa is the non-activated, non-psychotropic acid form of THC. The solvent extract filtrate typically contains a higher percentage of cannabinoid(s) and/or terpenes than the initial solvent extract. Dried cannabis material (bud, trim, or fan leaves, milled) was obtained. Basically, the THCA molecule is a pseudo-polymorph, meaning it is able to change and crystallise into different forms under certain conditions of pressure, temperatures, and depending on the interactions between the solvents (in this case the various terpenes), the solutes, (the cannabinoids) and any impurities present (for example plant fats, Table 1 below shows the fate of initial and extracted solids and THC as a function of dry weight in a typical butane extraction contrasted with the products of the methods disclosed herein (Table 2).
