The present invention includes a method for obtaining a higher purity cannabinoid solvent extract from a plant which comprises cannabinoids and/or terpenes. Currently, THCA diamonds are the strongest form of cannabis on the market and truly pack a punch. It is ideal for those suffering from glaucoma, inflammation, and insomnia. Phone: 855-420-0020 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. 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. 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. All percentages and amounts in the present application, if not otherwise defined, are to be defined as weight percents (w/w). In one embodiment, the terpene/terpenoid includes limonene. The described examples are provided for illustrative purposes and are not intended to limit the scope of the invention. Methods to increase surface area for crystallization are known in the art, such as glass beads, which are optionally added prior to the crystallization. These higher weight impurities can comprise, for example, such materials common to plants such as lignin, lignans, pigments, gums, lignocellulosic material, and lecithin. That extract is then combined with acetic acid and hexane, which serve as solvents and dissolve away the plant compounds, such as terpenes, fats, lipids, and other cannabinoids. This application claims priority to pending U.S. In general, a crude extract of cannabis can be made via solvent extraction. THCA and CBDA crystals can be heated through a variety of ways including vaporization, dabbing, or cooking. That extract is then combined with acetic acid and hexane, which serve as solvents and dissolve away the plant compounds, such as terpenes, fats, lipids, and other cannabinoids. 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. Its neutral taste, sugar-like appearance, and non-psychoactive properties (as long as not heated) make it appealing for many medicinal cannabis users. Five Facts You Need to Know About Cannabinoid Crystals. An exemplary cannabichromene (CBC) is shown below: CBC, like THC and CBD, results from CBCa. 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. Then, cannabis extract is mixed with acetic acid and hexane. When the process is complete, crystal looks like, well, small crystals. so thc cant be oil because it has crystals buds seeds stems flower..roots . The scope of the present invention is limited only by the scope of the following claims. Two morphologies of crystals were observed, sheet and ball crystals. by floating layers of particulate material, Heating or cooling mechanisms specially adapted for settling tanks, Fractional crystallisation; Fractionating or rectifying columns, ABANDONED -- FAILURE TO RESPOND TO AN OFFICE ACTION, High on Fire: Making Butane Hash Oil" online "https://www.celebstoner.com/blogs/doug-mcvay/2013/02/01/high-on-fire-butane-blazes-burning/, Methods for the Analysis of Cannabinoids in Biological Materials: a Review, Yields according to the instant invention, Methods for Extraction and Isolation of Isoprenoid and Terpene Compounds from Biological Extracts, Phytochemical extraction system and methods to extractphytochemicals from plants including plants of the familycannabaceae sensu stricto, Processes for the isolation of a cannabinoid extract and product from cannabis plant material, Crystal purification in a glass or metal container, Processes for solvent extraction of cannabinoids, terpenes and flavonoids from biomass, Aqueous Leaching Method to Produce Microcrystalline Powder, Resinous compound crystallization using non-polar solvent sequence, Rapid botanical oil distillation device utilizing microwave agent, Purification of Cannabinoids From Crude Cannabis Oil, Solid compositions of cocrystals of cannabinoids, Method for purifying crystals using solvent vapors, Continuous crystallization of cannabinoids in a stirred-tank reactor, Apparatus for purifying crystals using solvent vapors, Optimizing volatile entourages in dry flowering plant mixtures, Systems and methods for cannabis extraction, Method of converting delta9-THC to delta10-THC and the purification of the delta10-THC by crystallization, Compound extraction from plant based material utilizing terepene saturant, Methods of purifying cannabinoids from plant material, Extraction of pharmaceutically active components from plant materials, Pharmaceutical composition and method of manufacturing, Methods for extraction and isolation of isoprenoid and terpene compounds from biological extracts, Phytochemical extraction system and methods to extract phytochemicals from plants including plants of the family Cannabaceae sensu stricto, Processes for the isolation of a cannabinoid extract and product from Cannabis plant material, Aqueous leaching method to produce microcrystalline powder, Purification of cannabinoids from crude cannabis oil, Cannabis extracts and methods of preparing and using same, Cannabidiol isolate from industrial-hemp and use thereof in pharmaceutical and/or cosmetic preparations, Process for the production of an extract containing tetrahydrocannabinol and cannabidiol from cannabis plant material and cannabis extracts, Cannabis plant isolate comprising .delta.9-tetrahydrocannabinol and a method for preparing such an isolate, Compositions comprising cannabinoids for treatment of nausea, vomiting, emesis, motion sickness or like conditions, Isolation of herbal and cannabinoid medicinal extracts, Novel eucalyptus extract, preparation method thereof and therapeutic use thereof, Method of isolating tetrahydrocannabinol from cannabis sp and uses thereof, Process and apparatus for multi-phase extraction of active substances from biomass, Methods for increasing coumarin and scopoletin contents in Artemisia Capillaris, and the method for extraction of coumarin and scopoletin having increased contents, Method of extracting high concentration cannabinoid oil from hemp seed, The Effect of Drying on Chemical Composition and Antioxidant activity ofCymbopogon citratus and Cymbopogon schoenanthus (L.) spring (proximus) Growing in Sudan, Determination of the Optimum Extraction Conditions of Phytoflavonoids and Their Idetification for two Medicinal Herbs, Chemical Characterization of Marhabaib (Cymbopgon) Leaves, Spikes and their Essential Oil, A method of extraction for plants belonging to the cannabaceae family, PHYTOCHEMICAL SCREENING AND CHEMICAL ANALYSIS OF CLOVES (SYZYGIUM AROMATICUM) FLOWER BUDS, A method for extracting and concentrating polyphenol from grape branch, Information on status: application discontinuation. By using pressure, motion, and heat, the solvent is evaporated, leaving behind 9 tetrahydrocannabinolic acid. In practice, because THCA spontaneously decarboxylates to form THC, no real sample of purified THCA will be completely free of THC. In the example illustrated in Table 2, the filtrate THCa concentration has increased from 75% to 77%. Indeed, in California, cannabis flowers currently make up just over half of the market (55% in the 2nd quarter of 2017. Therefore, in one embodiment, the cannabis is dried. 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. Its widely regarded as the most potent form of marijuana, as it contains ~99.96% THCA. In one embodiment, the present invention includes a step of a solvent extraction of the plant which comprises cannabinoids. This is the story of delta 10-tetrahydrocannabinol (10-THC) and its mysterious formation and crystallization following distillation. The next part of the process utilizes machinery, such as a rotary vessel or reactionary vessel. But THC does more than just take you on a nice trip. Afterward, pentane is used to remove the smallest bits of non-THC or non-CBD material and then roto-vaped for the last time. 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 about 12 hours and three days to obtain crystals of THCa of greater than about 95% purity. In one embodiment, the crystallization step is encouraged and/or enhanced by increasing surface area. This method may further optionally include the step of crystallizing the THCa from the solvent extract filtrate. 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. All references cited herein are incorporated in their entirety by reference. Acetone tends to be fairly volatile at room temp, and can be removed via vacuum and heat, over time, in a vacuum oven. THCV also holds anti-convulsive properties useful for treating epilepsy. 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. Where the starting plant material is freshly harvested or wet, the plant material may be subjected to a drying step to remove excess moisture or a freezing step to immobilize moisture in the plant. Glass beads were added to the beaker before putting it into an undisturbed deep freeze (75 C.). In this step, the solvent extract filtrate can be treated to allow the THCa to crystallize out of solution. 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 there are no terpenes, THCA crystalline does not have a strong taste. 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. 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%. In another embodiment, the terpene/terpenoid includes linalool. In the case where no THCa is present in the initial extract, such as hemp or a plant other than a species of cannabis, the resulting filtrate is not subjected to a secondary separation step. Crystals formed in between 12 hours and several days. 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. What Happens If You Mix Cannabis With Psilocybin? this bud has little things that look like crystals. The solvent may include a short chain hydrocarbon, such as, for example, butane; carbon dioxide, an alcohol, or a terpene. 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. 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. Alternatively, the cooling step may take place for longer than one hour longer than about ten hours, longer than about 18 hours, longer than about 24 hours, longer than about 36 hours, longer than about 48 hours, longer than about 72 hours, longer than about 96 hours, longer than about 120 hours, or about 168 hours or longer. The Growth factor dominates Nucleation in the equilibrium that exists between the two, and the conditions favor the formation of few, but large, crystals. THCa is the non-activated, non-psychotropic acid form of THC. Give it more time without disturbing it and it will sugar up. 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 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. 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. Terpenes are a diverse group of organic hydrocarbons derived from 5-carbon isoprene units and are produced by a wide variety of plants. Without them present, you still get the benefits of the THCA; you just dont get the added benefits from the terpenes. Winterizing will clean up your fats to give you a somewhat crystalline product at over 80% THCA. 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. CBD does not display the psychoactive effects of , A cannabinoid useful for the present invention also includes cannabichromene type, or. 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. In one embodiment, the solvent extract is cooled to allow for precipitation of the higher molecular weight impurities. 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. Post chromatography, the crystals are dissolved in methanol and then filtered and then roto-vaped to remove the methanol. Its IUPAC name is (1S,5S)-2,6,6-Trimethylbicyclo[3.1.1]hept-2-ene (()--Pinene). 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. What Is THCA (pure THC crystals) and CBD Crystalline? When you see keef weed crystals on your herbal bud, you are witnessing what a pure marijuana crystal is . 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 present inventor has found that if yellow oil is present with the crystals, the separation from the other terpenes has ceased to be effective. The crystalline substance being isolated in this technique is THCA (with the carboxylic acid still attached). CBD can occur in up to 40% of the cannabinoid extracts from cannabis. 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. Citral, or 3,7-dimethyl-2,6-octadienal or lemonal, is either a pair, or a mixture of terpenoids with the molecular formula C, In another embodiment, the terpene/terpenoid includes humulene. The preferred crystallization container material is glass. Occasionally crystals will not form, even though the saturation point has been reached. 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. With potencies pushing 99.9 percent - it's not hard to see why. FINAL REJECTION MAILED, Free format text: Pinene is found in conifer, pine and orange. The following examples are provided for illustrative purposes only and are not intended to limit the scope of the invention. The solvent extract filtrate can be collected and used in the crystallization step without any further modification. 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. That's fine, high terp oils tend to sugar. One of the main benefits is its high concentration of THCAover 99%. 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. The end product itself has many benefits, especially for those looking to solely reap the benefits of THCA without any extra compounds present. 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. Additional usages include use in edibles, and so these crystals are very flexible. The methods of the present invention are also optionally useful to obtain a higher purity of terpene(s). The developing crystals ideally form with high purity, while impurities remain in the . Terpene Content: B-Myrcene, D-Limonene, B-Caryophyllene. The present invention is directed toward overcoming one or more of the problems discussed above. . 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. The target compound of interest, is dissolved in a specific solvent to form a solution. As used herein, the expression tetrahydrocannabinol or THCwhere not otherwise specifiedis to encompass any isomers thereof, in particular double bond isomers. For those who need a high concentration, this is a great option to get the most for your money. The present inventor also found methods to crystallize THCa from, for example, extracted bud and higher-quality trim. Alternatively, the solvent may be removed from the extract and the extract re-solubilized in a different solvent. TetrahydrocannabivarinTHCV is structurally similar to THC, but acts an antagonist to the CB1 & CB2 receptors in the body. 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. 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. The below table shows yields from each step of the process. 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. In another embodiment, the terpene/terpenoid includes myrcene. Racemic limonene is known as dipentene. The alternatives are to do ethanol extraction at an ambient temperature or in highly cool conditions.

It is usually found as a mixture with isocaryophyllene (the cis double bond isomer) and -humulene, a ring-opened isomer. Optionally, the crystallization may be performed under pressure or vacuum. To achieve their desired taste preferences, many people combine THCA crystalline with terpenes. While a variety of extraction techniques have become commonplace in cannabis, a secondary separation step is rarely employed. 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. A cannabinoid useful for the present invention also includes a cannabidiol type. 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. Concentrates especially have become increasingly popular over . We cover the five most fascinating tidbits about CBD and THCA diamonds, from their laborious production to sky-high potency. The plant may be cannabis or hemp, and the cannabinoid may be tetrahydrocannabinolic acid (THCa). The sky's the limit when it comes to concentrates. The most potent stereoisomer occurs naturally as . Delta-8 THC has the same number of atoms as delta-9, but their arrangements differ, and this . The solvent extract may comprise tetrahydrocannabinol, cannabidiol, and the carboxylic acids thereof from cannabis plant material. 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. Structures are shown in Fig. Limonene is a chiral molecule. Cannabis Diamonds Are Non-Intoxicating. Growth is the term that defines the rate at which individual crystals that are formed become larger. When growing crystals, there are two concurrent processes that are kept in balance. 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. Crystals of THCA synthase. As these gas off into our jar head space, the content (%) of THCa very slowly increases allowing crystallization to occur, as the gas and terpene % decreases. 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. dabsRosin on February 14, 2021 at 7:36 am THC is a crystal . It is also known as 4-isopropenyl-1-methylcyclohexenep-Menth-1,8-dieneRacemic: DL-limonene; dipentene. At small to moderate values of (T) and/or (T/t), the pressure to crystallize can be thought of as being small. Generally, the solvent extraction step can be carried out by methods that are known in the art. 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. 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. [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). THCa crystals can power both the most radical dabs and the most approachable topicals. Due to its small quantity in the cannabis plant, CBC works best in conjunction with CBD and THC. . Optionally, the plant material comprises dried bud, trim, or fan leaves, which are optionally milled. 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.
