To create sauce, the extracted THCA diamonds are then recombined with the concentrate. The cannabis plant is the primary source of cannabinoids Like all terrestrial plants, lignocellulose gives the plant its structure. In particular, the extract may contain lignin, lignans, gums, pigments, and lecithin. 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. Cannabinoids may also occur as their pharmaceutically acceptable salts. In another embodiment, the terpene/terpenoid includes citral. 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. The extract was collected in a beaker and placed on dry ice in a cooler. In other words, all THC was once THCA. [2] The effect that this undercooling has on the type of crystals that are formed depends in part on how far below the freezing point the solution is driven down (T), and in part by how fast that cooling temperature is applied and transferred to the solution (T/t). While various aspects and features of certain embodiments have been summarized above, the following detailed description illustrates a few embodiments in further detail to enable one of skill in the art to practice such embodiments. -Pinene is a major constituent in turpentine. This solution still contains a variety of unwanted compounds that can be removed through a process called chromatography. Regulatory compliance is always subject to local codes and regulations, In one embodiment, the crystallization step is encouraged and/or enhanced by increasing surface area. To make THCA crystalline, you start with a cannabis extract. 9.5.1 Holy Anointing Oil; 9.5.2 Graywolf's EZ CBD Topical; 9.5.3 . 9. Description: A live concentrate with a thin liquid consistency studded by medium to large THCa crystals that are coated in terpenes to enhance the product's color, flavor, and potential benef. An impure solid is completely dissolved in a minimal amount of hot, boiling solvent, and the hot solution is allowed to slowly cool. 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. . Moreover, the use of the term including, as well as other forms, such as includes and included, should be considered non-exclusive. The Benefit of Rosin for THCa . For those who need a high concentration, this is a great option to get the most for your money. The sky's the limit when it comes to concentrates. However, these techniques either tend to be difficult to scale and make continuous, or tend to degrade the molecules of interest. 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. As an example of a device to facilitate cooling the solvent extract on dry ice, Pelican ProGear Elite Marine Deluxe Coolers work especially well for maintaining low temperatures when filled with dry ice. Acetone tends to be fairly volatile at room temp, and can be removed via vacuum and heat, over time, in a vacuum oven. NOTICE OF APPEAL FILED, Free format text: The described examples are provided for illustrative purposes and are not intended to limit the scope of the invention. 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. The methods of the invention result in obtaining a solvent extract filtrate which has a higher purity of the at least one cannabinoid. We have several different solutions based on your desired throughput capacity The SKU Options of Short Path vs. THC-A Crystalline Hash is the holy grail of cannabis potency. 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. The solvent extract, either used as collected, or adjusted in volume or type of solvent as discussed above, is then used in the additional step(s) of the method. In addition, because the end product has not been decarboxylated, it will not give you a high as long as it is not heated. The cooler is optionally between about 40 C. and 70 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.

It is also time and labor-intensive. The crystallized THCa may be used in the acid form, or converted to the neutral form by methods known in the art. Alternatively, the solvent may be removed from the filtrate and the filtrate re-solubilized in a different solvent or solvents for the crystallization step. Caryophyllene is notable for having a rare cyclobutane ring. 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. When dried and/or heated, THCA decarboxylates and turns into THC. Make sure the vessel condenser is cooled to -20 C. In another embodiment, the terpene/terpenoid includes -Pinene. Alternatively, the solvent may be removed from the extract and the extract re-solubilized in a different solvent. C1D1 compliant PSI Certified - 50 State Compliant RV 100 Reactionary Vessel Suitable for Cannabis & Hemp These steps are discussed hereinbelow. When the process is complete, crystal looks like, well, small crystals. Delta1-Tetrahydrocannabinolic acid (THCA) synthase is a novel oxidoreductase that catalyzes the biosynthesis of the psychoactive compound THCA in Cannabis sativa (Mexican . It is the second most abundant natural polymer in the world, surpassed only by cellulose. Ed Rosenthal, author of Beyond Buds, has recently explored these products in a potent online expose. The Growth factor dominates Nucleation in the equilibrium that exists between the two, and the conditions favor the formation of few, but large, crystals. For example, to obtain crystals of THCa, the solvent extract filtrate may be cooled to a temperature of about 75 C. for a time period of between . Generally, to perform the solvent extraction step, the solvent is passed over hand harvested or milled plant materials in order to extract concentrated fractions. Wash using a pipette: used for small amount of crystals to be washed. 62/188,965 entitled Methods for Obtaining Purified Cannabis Extracts and THCA Crystals, filed Jul. Its IUPAC name is (1S,5S)-2,6,6-Trimethylbicyclo[3.1.1]hept-2-ene (()--Pinene). Cons This process requires expensive, special equipment and knowledge of cannabis extraction methods. Afterward, pentane is used to remove the smallest bits of non-THC or non-CBD material and then roto-vaped for the last time. That being said, if the product is heated, it becomes THC (not THCA), and it will give you a high. Pure THC crystals are one of the newest and most exciting trends in extraction technology. The precipitate can be removed from the cooled solvent extract by any methods known in the art. The Two-Way Relationship Between Cannabis and its Dibble, Clare J. and Cole, Isaac B. THC crystals, more accurately known as THCA crystalline, isn't a product for everyone. Typically in cannabis extracts, such a carrier solvent is typically removed immediately following an extraction process. In another embodiment, the terpene/terpenoid includes -Pinene. 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. If vaporized, this filtrate leaves no residue or a light waxy white residue, but no carbonized black residuals. THCa not only has anti-proliferative abilities that are crucial in helping inhibit the growth of cancerous cells, but also, it has anti-spasmodic abilities that helps subdue muscle spasms and therefore has potential use among epileptic patients. With potencies pushing 99.9 percent - it's not hard to see why. How are the Diamonds Made? Phone: 855-420-0020 THCA is the acidic form of delta-9 THC, the most prominent intoxicating compound in cannabis. It turns acidic compounds like tetrahydrocannabinolic acid (THCA) into THC, along with a variety of other cannabinoids. Crude extracts from cannabis plants are often used by patients suffering from diseases and disorders, such crude products are less suitable for use in pharmaceutical formulations. Like x 2. The developing crystals ideally form with high purity, while impurities remain in the . After collecting the crystals, the butane and extract mixture were returned to the deep freeze to collect additional crystals. A solvent extraction is performed on the optionally dried plant material, followed by a step of removing high molecular weight impurities by a cooling step. To achieve their desired taste preferences, many people combine THCA crystalline with terpenes. It is also known as 4-isopropenyl-1-methylcyclohexenep-Menth-1,8-dieneRacemic: DL-limonene; dipentene. Nucleation determines how quickly new crystal seeds are formed in the container. you can get high-potency (>72%) THCA through "low and slow''subcritical CO2 extraction. 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. 1. For example, the precipitate can be removed by filtration, or by transferring the supernatant to a clean vessel. Lignin, as a structural polymer, would not typically be extracted with polar solvents such as water, but may be extracted with non-polar solvents used to extract resins. Concentrates especially have become increasingly popular over . Without them present, you still get the benefits of the THCA; you just dont get the added benefits from the terpenes. When you see keef weed crystals on your herbal bud, you are witnessing what a pure marijuana crystal is . In this embodiment, the filtrate is returned to a clean beaker and the cooling step is repeated, followed by the step of removing the precipitate. The term plant includes a plant or plant part such as bark, wood, leaves, stems, roots, flowers, fruits, seeds, berries or parts thereof). Its IUPAC name is 6,6-dimethyl-2-methylenebicyclo[3.1.1]heptane and is also known as 2(10)-Pinene; Nopinene; Pseudopinene. The present inventor has found that if yellow oil is present with the crystals, the separation from the other terpenes has ceased to be effective. In the example illustrated in Table 2, the filtrate THCa concentration has increased from 75% to 77%. Crystalline THCA is a product of growing popularity due to its potential to reach extremely high potencies. A cannabinol useful for the present invention also includes tetrahydrocannabivarin (THCv) having a propyl side chain. The solvent extract filtrate, following this step, may be optionally dried by methods known in the art to remove the solvent. 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. Additional usages include use in edibles, and so these crystals are very flexible. 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. Produced and stored inside of the trichomes on cannabis flowers and leaves, THCA is far more abundant in . After two filterings, the solvent extracts were optically clear. 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. Free format text: This residual filtrate contained cannabinoids and terpenes extracted from the original bud or trim, and THC and THCa that did not crystallize during the course of the run. One of the main benefits is its high concentration of THCAover 99%. 600 mL of cooled 99+% pure n-butane or (or 95% n-butane with 4.1+% iso-butane) (for example, 10 C. or colder) is allowed to pass over the column. The crystallization model described in 2 . So the better the isolation, the higher the THCa content, the lower the terpene content (the part with flavor). All references cited herein are incorporated in their entirety by reference. The trend of supersaturation generation during the process has a direct and significant role on crystal characteristics such as size, morphology, and purity. The filtrate, crystallized THCa, and residual filtrate remaining after crystallization of THCa can be used as starting materials for products that include cannabinoids and/or terpenes. The ratio of solvent to dry weight of plant matter extract can be adjusted by adding more of the same solvent, a different solvent, or removing some proportion of solvent. 3.6A: Single Solvent Crystallization. Methods for Obtaining Purified Cannabis Extracts and THCA Crystals. Sauce is usually dabbed at low temperatures using a glass rig. It resembles coarse sugar in its appearance. Alternatively, the solvent extract filtrate can have the ratio of solvent to dry weight of filtrate adjusted by adding more of the same solvent, a different solvent (co-solvent), or removing some proportion of solvent. In another embodiment, the terpene/terpenoid includes linalool. Most people when they here pure crystal, they think of the pure crystal dust location in World of Warcraft. In general, a crude extract of cannabis can be made via solvent extraction. Myrcene, or -myrcene.

In much of the chemical industry, recrystallization is used to achieve very high purity on a large scale without complex equipment. Various modifications and additions can be made to the embodiments discussed without departing from the scope of the invention. The extract was filtered through a vacuum assisted Buchner funnel using 12.5 cm diameter 101 fast filter paper and coffee filter taking care not to disturb the cake on the bottom of the beaker. Limonene is a chiral molecule. There are several different ways to go about extracting isolates, which utilize chemical processes and a myriad of other techniques. Its widely regarded as the most potent form of marijuana, as it contains ~99.96% THCA. The solvent extract filtrate can be collected and used in the crystallization step without any further modification. The Spiritual Cannabinoid Guide. Lineage: Double Afghan Chunk x Marie Laveau. You can easily incorporate THCA crystals into a variety of food and drink, as it is flavorless. While all natural product precursors exhibit inherent variation, it is desirable to obtain a consistent product from any part of the plant that contains that product within a single harvest and from different harvests. When you consume the product, you get an extremely concentrated amount of THCA, but you also lose out on the terpenes and cannabinoids that are naturally present in the marijuana plant. We cover how to produce quality hydrocarbon crude, and how . When repeatedly purified using the rosin technique, THCA . In another embodiment, the terpene/terpenoid includes caryophyllene, also known as -caryophyllene. Currently, THCA diamonds are the strongest form of cannabis on the market and truly pack a punch. 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. If it's 95%, that's very little of anything else THCA is one type of chemical present in the cannabis plant. It is usually found as a mixture with isocaryophyllene (the cis double bond isomer) and -humulene, a ring-opened isomer. In one embodiment, the invention includes tetrahydrocannabinols, including the most commonly known cannabinoid, tetrahydrocannabinol (THC). The solvent may include a short chain hydrocarbon, such as, for example, butane; carbon dioxide, an alcohol, or a terpene. The dried solvent extract filtrate can then be used as desired, as a typical oil, shatter or wax that has not undergone a separation process. 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. The clinical usefulness of the cannabinoids, including . Lignocellulosic material is composed of carbohydrate polymers such as cellulose and hemicellulose, crosslinked to an aromatic polymer (lignin). "A mix of THC and THCA doesn't crystallize." For THCA, the process of crystallization takes at least two weeks, sometimes a month, but such patience is rewarded. The answer is a resounding yes, but you'll need to add heat first. 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. As you hone your rosin-making abilities, you can venture into more advanced techniques like jar tech which involves carefully manipulating temperature inside of a sealed jar to induce THCA crystallization and create "diamonds" and other novel rosin forms. Limonene is a colorless liquid hydrocarbon classified as a cyclic terpene. If not you can throw some pre-existing THCA crystals into your solution. It's fine. 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. In one embodiment, the method includes a step of performing a solvent extraction of the plant to obtain a solvent extract. The method then comprises cooling the solvent extract to allow the THCa to crystallize from the solvent extract according to the methods disclosed in the present invention, and collecting the crystallized THCa. THCA crystalline can be incorporated into food using a carrier oil, such as olive oil or coconut oil. Crystals formed in between 12 hours and several days. Two flash chromatography systems that can be used independently from each other were developed to In many instances, administration in conjunction with the subject products enhances the efficacy of such agents. What is CBN, and Is It the Next Big Thing? 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. Exemplary cannabinoids useful for the present invention include cannabinols. The method includes the steps of performing a solvent extraction of the plant to yield a solvent extract, cooling the solvent extract; and removing the precipitate from the cooled solvent extract to yield a solvent extract filtrate. THCA crystals are an interesting product! Lignin is commonly understood as a complex polymer of aromatic alcohols and is a component of the cell walls of plants. So basically you're seeing crystallization on a very small scale. 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. Finally, this last step is being repeated once again using a dissolvent to purify it to 99.997%. Crystals of THCA synthase. THCa is the non-activated, non-psychotropic acid form of THC. Its IUPAC name is 4,11,11-trimethyl-8-methylene-bicyclo[7.2.0]undec-4-ene. The embodiments described and shown in the figures were chosen and described in order to explain the principles of the invention, the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

The extract to be purified can be from any vegetation, but this method is particularly suited to cannabis. Then, cannabis extract is mixed with acetic acid and hexane. The methods of the invention also include a method for obtaining crystallized THCa, which comprises obtaining a filtrate by the methods disclosed herein, or obtaining a solvent extract, and allowing crystallization of the THCa to occur. In one example, crystals may be obtained 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. Which morphology dominates seems to be influenced by the process conditions and the quality of the starting material. Scroll down to see the most popular usage methods. Some crystals may have terpenes to improve the marijuana concentrate's flavor and efficacy. In another embodiment, the terpene/terpenoid includes myrcene. Make sure enough solvent has evaporated before you do this or you'll just dissolve a good diamond. 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. Lets dive into the process of making THCA crystalline, as well as some of the benefits and drawbacks of the product. Many people prefer this, as they get all the benefits of THC without the psychoactive effects. In a well ventilated area, two 300 mL cans of 10 C. 99+% pure n-butane were poured into the top of the column, about 5-10 minutes. 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). In addition, because there are no terpenes, THCA crystalline does not have a strong taste. This method includes the steps of performing a solvent extraction of the plant to yield a solvent extract; a step of cooling the solvent extract; and a step of removing the precipitate from the cooled solvent extract to yield a solvent extract filtrate, wherein the solvent extract filtrate has a higher purity of the at least one cannabinoid. 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. To much pressure and nothing can gas off as the BP of your terps, cannabinoids, and gas gets to high. Dried cannabis material (bud, trim, or fan leaves, milled) was obtained. While psychoactive, THCV lends itself to a shorter, psychedelic, clear-headed effect which is shorter lasting that THC. solvent should be used for the recrystallization, and a MINIMUM of ICE-COLD solvent should be used for the rinse. Plant pigments include chlorophyl and other carotenoids that absorb light to catalyze photosynthesis. [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. If a recrystallization solution has been allowed to cool and crystals have not formed, it may be due to a condition known as supersaturation. THCa, the acid precursor to THC, was crystallized out of solution using the filtered solvent extract. When growing crystals, there are two concurrent processes that are kept in balance. This process is not intended for removal of entrained solids, but can handle small amounts of material that may inadvertently be included in the mixture. 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 target compound of interest, is dissolved in a specific solvent to form a solution. It's often called an "isolate," particularly when the CBD in cannabis is the cannabinoid that's left. The compositions may be combined with a pharmaceutically acceptable excipient such as gelatin, oil(s), and/or other pharmaceutically active agent(s).

Extraction solvents for use in the methods of the present invention include non-polar solvents such as short chain hydrocarbons (including, for example, propane, butane, hexane, and the like), alcohols such as ethanol or methanol, and liquid and/or supercritical carbon dioxide, steam, and terpenes. And, because the product contains such a high concentration of THC, it will give you a powerful high in a small amount of product. ), 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 . We cover the five most fascinating tidbits about CBD and THCA diamonds, from their laborious production to sky-high potency. Heating for 5 minutes at a temperature of 200-210 C. will accomplish decarboxylation. 50 g plant matter was added to a 1.5 inch diameter aluminum column 12 inches in length, supported by a stand with a screen secured on the bottom and rubber stopper with a center hole containing a nozzle on the top. Fast-Acting Nano-Based Products Are Boring. In other embodiments, the plant material has been subject to a decarboxylation step and the cannabinoids are present as their neutral forms. Essentially, crystal is a cannabis concentrate that's been processed so that the only compound it contains is a single cannabinoid like THC or CBD. No. This application claims priority to pending U.S. The liquid that flows from the packed bed can be collected in a beaker below the screen end of the tube. CBD can occur in up to 40% of the cannabinoid extracts from cannabis. 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. In another embodiment, the cannabis is frozen. Also called 9-tetrahydrocannabinolic acid, or THCA, this cannabinoid is the natural acidic precursor of THC (the psychoactive cannabinoid that drives many of cannabis' effects). The link below has bit of general info about THCA. See also. In one embodiment, the solvent extract is cooled to allow for precipitation of the higher molecular weight impurities. The non-structural chemical components of plant cells are much more highly variable from plant to plant and within different parts of a plant.
