The process starts with a cannabis extract. The present inventor has found that after two filterings, the solvent and extract are typically significantly more pure. 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. The cooling step may take place for between about 1 minute and 24 hours, between about 10 minutes and about 18 hours, between about 30 minutes and about 12 hours, between about one hour and about 8 hours, between about 2 hours and about four hours. -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. With potencies pushing 99.9 percent - it's not hard to see why. At small to moderate values of (T) and/or (T/t), the pressure to crystallize can be thought of as being small. The Benefit of Rosin for THCa . 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. So you can't have both, cannot have a super high THCa without low terpene. Decarboxylation converts most of the acid into THC or CBD. We have several different solutions based on your desired throughput capacity 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. A cannabinoid useful for the present invention also includes cannabinol (CBN). To make THCA crystalline, you start with a cannabis extract. CBD and THCA diamonds are made by removing the crystalline structures from the runny terp sauce. Cannabinoids are the class of chemicals that make the cannabis plant unique, but terpenoids, sugars, fatty acids, flavonoids, other hydrocarbons, nitrogenous compounds, and amino acids have also been identified in cannabis plants. ), 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 . Crystals of THCa can be harvested by methods known in the art. For example, while the embodiments described above refer to particular features, the scope of this invention also included embodiments having different combination of features and embodiments that do not include all of the above described features. The Spiritual Cannabinoid Guide. If it's 95%, that's very little of anything else After two filterings, the solvent extracts were optically clear. Dried cannabis material (bud, trim, or fan leaves, milled) was obtained. From a medical standpoint, THCA is a good choice in which you can still use to serve as a stress and pain-relieving remedy without giving the stoned sensation as the THC. For the consumer, this advantage is apparent. 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. When you have an isolate product like this, it's THCa that's been, you know, isolated. As he points out, Diamond Mining, or Jar Tech, is really a derivative of the basic organic chemistry concept called Recrystallization. How to Make THCa Crystals in a Mason Jar | THCa Crystallization Technique - YouTube Home Shorts Subscriptions Library History How to Make THCa Crystals in a Mason Jar | THCa. Its widely regarded as the most potent form of marijuana, as it contains ~99.96% THCA. 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. Without being bound by theory, the present inventor believes that the high molecular weight impurities to be lignin, lecithin, and/or other undesirable, high molecular weight materials that were extracted by the solvent. In some embodiments, the high molecular weight impurities present in the solvent extract turn dark when exposed to air. Glass beads were added to the beaker before putting it into an undisturbed deep freeze (75 C.). This process can reduce the number of plant pigments and waxes in the end product but . It will not get you high, instead require heat to turn into a THC molecule which is why you smoke or vape. It turns acidic compounds like tetrahydrocannabinolic acid (THCA) into THC, along with a variety of other cannabinoids. The target compound of interest, is dissolved in a specific solvent to form a solution. Shea, Thomas and Hammer, Julia E. Kinetics of cooling- and decompression-induced crystallization in hydrous mafic-intermediate magmas. THCA crystalline is a newer, extremely potent extract on the market. This application claims priority to pending U.S. What is CBN, and Is It the Next Big Thing? Alternatively, the solvent may be removed from the filtrate and the filtrate re-solubilized in a different solvent or solvents for the crystallization step. Afterward, pentane is used to remove the smallest bits of non-THC or non-CBD material and then roto-vaped for the last time. Its IUPAC name is 7-methyl-3-methylene-1,6-octadiene. Lignin is a constituent of the cell walls of almost all dry land plant cell walls. The non-structural chemical components of plant cells are much more highly variable from plant to plant and within different parts of a plant. It is time to clear the smoke and demystify the hottest new cannabis concentrate on the market. The scale bar is 0.1 mm in length. The plant which comprises at least one cannabinoid optionally further comprises at least one terpene and/or terpenoid. Add 1 part pentane to 2 parts CBD oil (some oils require slightly more or less pentane) in the jacketed vessel. Thus, the solvent extract filtrate, either used as collected, or adjusted in volume or type of solvent as discussed above, is then optionally used in the crystallization step. The results, white crystals testing at 99.97% cannabinoid. Turn on stirring and turn on the heating bath and set to 45 C. When you see keef weed crystals on your herbal bud, you are witnessing what a pure marijuana crystal is . 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. CBD can occur in up to 40% of the cannabinoid extracts from cannabis. THCA crystals are an interesting product! 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 more optically clear the solvent is, the better the separation has gone. 2. Humulene, also known as -humulene or -caryophyllene, is a naturally occurring monocyclic sesquiterpene (C. Other exemplary terpenes/terpenoids include menthol, eucalyptol, borneol, pulegone, sabinene, terpineol and thymol. 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. 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. 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. US Patent number US20170008870A1. However, the sky's the limit. The most potent stereoisomer occurs naturally as . This pure THCa converts to THC when vaped and creates a clear and highly cerebral effect, or remains non-psychoactive . In other embodiments, the plant material has been subject to a decarboxylation step and the cannabinoids are present as their neutral forms. The compositions may be combined with a pharmaceutically acceptable excipient such as gelatin, oil(s), and/or other pharmaceutically active agent(s). 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. Its IUPAC name is 4,11,11-trimethyl-8-methylene-bicyclo[7.2.0]undec-4-ene. The cannabis plant is the primary source of cannabinoids Like all terrestrial plants, lignocellulose gives the plant its structure. The present invention is directed toward overcoming one or more of the problems discussed above. Lineage: Double Afghan Chunk x Marie Laveau. All references cited herein are incorporated in their entirety by reference. In one embodiment, the terpene/terpenoid includes limonene. THCA and CBDA crystals can be heated through a variety of ways including vaporization, dabbing, or cooking. Various modifications and additions can be made to the embodiments discussed without departing from the scope of the invention. You can easily incorporate THCA crystals into a variety of food and drink, as it is flavorless. 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 time, you will squeeze THCA crystals from the bag, hardening near instantly, as they remain on your screen. Caryophyllene is notable for having a rare cyclobutane ring. And while this is certainly a benefit for some, its important to recognize that its potency could be a drawback, especially for an inexperienced user. One of the main benefits is its high concentration of THCAover 99%. When exposed to heat, non-intoxicating THCA converts to intoxicating THC and produces that classic cannabis high. If not you can throw some pre-existing THCA crystals into your solution. An impure solid is completely dissolved in a minimal amount of hot, boiling solvent, and the hot solution is allowed to slowly cool. Your extract will come out as an off yellow powder. The future of Botanical Extraction Market. 9. What Is THCA (pure THC crystals) and CBD Crystalline? Optionally, THCa may be precipitated directly from the extract making the filtrate lower in (THC+THCa) but replete with cannabinoids and terpenes from the plant. The second step requires the puck to be pressed once again at a higher temperature of 250F or higher. While some cannabinoids are removed with this sediment, their concentration is lower than the concentration in the original extract, leaving a filtrate enriched in at least one cannabinoid. The scope of the present invention is limited only by the scope of the following claims. The solvent extract filtrate, following this step, may be optionally dried by methods known in the art to remove the solvent. Two morphologies of crystals were observed, sheet and ball crystals. Plant lignans are polyphenolic substances derived from phenylalanine via dimerization of substituted cinnamic alcohols, known as monolignols. It also recommends against smoking, since heating will change THCA into THC through decarboxylation. The principle cannabinoids present in herbal cannabis are cannabinoid acids . The present invention also includes a method for obtaining crystallized THCa from a plant which comprises at least one cannabinoid, such as THCa, directly from the solvent extract. FINAL REJECTION MAILED, Free format text: Table 1 Data-collection and reduction statistics. The SKU Options of Short Path vs. After collecting the crystals, the butane and extract mixture were returned to the deep freeze to collect additional crystals. Email: info@precisionextraction.com a) performing a solvent extraction of the plant to yield a solvent extract; c) 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. [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. In the example illustrated in Table 2, the filtrate THCa concentration has increased from 75% to 77%. 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. Edit: THC is an oil; it is not crystalline. The developing crystals ideally form with high purity, while impurities remain in the . 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. The below table shows yields from each step of the process. But THC does more than just take you on a nice trip. solvent should be used for the recrystallization, and a MINIMUM of ICE-COLD solvent should be used for the rinse. 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. And, because the product contains such a high concentration of THC, it will give you a powerful high in a small amount of product. Growth is the term that defines the rate at which individual crystals that are formed become larger. 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. To discard the impurities represents a loss of 10% of the total extracted THCa or less. 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. When the process is complete, crystal looks like, well, small crystals. The residual filtrate, following crystallization of THCa, is relatively depleted in THCa, but will contain other cannabinoids and terpenes. THCA crystals are incredibly potent. THC-A Crystalline Hash is the holy grail of cannabis potency. The solvent extract filtrate typically contains a higher percentage of cannabinoid(s) and/or terpenes than the initial solvent extract. In one embodiment, 200 g or more of extracted plant matter is processed and 25 g or more product (THCa) is obtained. As used herein, the expression tetrahydrocannabinol or THCwhere not otherwise specifiedis to encompass any isomers thereof, in particular double bond isomers. Its IUPAC name is (1S,5S)-2,6,6-Trimethylbicyclo[3.1.1]hept-2-ene (()--Pinene). The following examples are provided for illustrative purposes only and are not intended to limit the scope of the invention. Indeed, in California, cannabis flowers currently make up just over half of the market (55% in the 2nd quarter of 2017. These steps are discussed hereinbelow. As pressure increases in the jar, so does the BP of everything in the jar. 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. Cannabinoids may also occur as their pharmaceutically acceptable salts. Its important to note that these terpenes and cannabinoids produce the entourage effect, which means they contribute to the efficacy of the marijuana ingestion. Crystallization is preferably carried out in highly non-polar solvents, such as hydrocarbons such as butane, oils such as vegetable oils and coconut oil or terpenes. When THCA is heated up past approximately 220 degrees Fahrenheit, it is converted to THC. These techniques are for you to further explore and expand your understanding of forming THCA diamonds. THCA is the acidic form of delta-9 THC, the most prominent intoxicating compound in cannabis. While psychoactive, THCV lends itself to a shorter, psychedelic, clear-headed effect which is shorter lasting that 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. The cannabinols have the following general structure: The cannabinoids include cannabinoids which have a carboxylic acid substituent, also known as cannabinoid acids, such as tetrahydrocannabinolic acid (THCa) which has a carboxylic acid at R. Decarboxylation of the cannabinoid acids to the corresponding phenols occurs over time, upon heating, or under alkaline conditions. Crystals formed in between 12 hours and several days. 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. 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. THCA crystalline is an isolated product, meaning as long as you take the same dose you should get a reasonably consistent experience. The present invention provides for the purity of the crystallized THCa to be at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% pure (w/w). This mixture will be put back in the rotary evaporator and mixed with quite some methanol which purifies it even more. 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. The described examples are provided for illustrative purposes and are not intended to limit the scope of the invention. Wash using a pipette: used for small amount of crystals to be washed. The crystallization step can be performed by methods as known in the art. By this point, the THCA molecules have chemically bonded to one another, forming a crystalline structure. Its IUPAC name is 3,7-dimethylocta-1,6-dien-3-ol. The products may be advantageously combined and/or used in combination with other therapeutic or prophylactic agents, such as one or more cannabinoids and/or terpenes.
