The methods of the present invention are also optionally useful to obtain a higher purity of terpene(s). NOTICE OF APPEAL FILED, Free format text: The second step requires the puck to be pressed once again at a higher temperature of 250F or higher. In one embodiment, 200 g or more of extracted plant matter is processed and 25 g or more product (THCa) is obtained. Figure 3.1: Various crystals. It will not get you high, instead require heat to turn into a THC molecule which is why you smoke or vape. The developing crystals ideally form with high purity, while impurities remain in the . The compositions may be combined with a pharmaceutically acceptable excipient such as gelatin, oil(s), and/or other pharmaceutically active agent(s). You can easily incorporate THCA crystals into a variety of food and drink, as it is flavorless. The balance of the THC and THCa remains in the solvent with the rest of the plant extract in the residual filtrate, which is enriched in cannabinoids and terpenes relative to the original plant extract. Like x 2. Therefore, in one embodiment, the cannabis is dried. So the better the isolation, the higher the THCa content, the lower the terpene content (the part with flavor). The solvent extract may comprise tetrahydrocannabinol, cannabidiol, and the carboxylic acids thereof from cannabis plant material. 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. While a variety of extraction techniques have become commonplace in cannabis, a secondary separation step is rarely employed. The Spiritual Cannabinoid Guide.

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). 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 other words, all THC was once THCA. 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. All references cited herein are incorporated in their entirety by reference. The crystallization model described in 2 . The present inventor has found two morphologies of crystals, sheet and ball crystals. THCA is the acidic form of delta-9 THC, the most prominent intoxicating compound in cannabis. Racemic limonene is known as dipentene. What Is THCA (pure THC crystals) and CBD Crystalline? Lignin is commonly understood as a complex polymer of aromatic alcohols and is a component of the cell walls of plants. you can get high-potency (>72%) THCA through "low and slow''subcritical CO2 extraction. 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. 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. The link below has bit of general info about THCA. The aforementioned doses of THCA are 10-100 times lower. The more common D-isomer possesses a strong smell of oranges and a bitter taste. Dried cannabis material (bud, trim, or fan leaves, milled) was obtained. Turn on stirring and turn on the heating bath and set to 45 C. In one embodiment, the terpene/terpenoid includes limonene. Its important to note that these terpenes and cannabinoids produce the entourage effect, which means they contribute to the efficacy of the marijuana ingestion. 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. We have several different solutions based on your desired throughput capacity ), 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 . 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. 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. 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. 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. * Actual amount of material per run and recovery times on any Precision extraction Additional usages include use in edibles, and so these crystals are very flexible. 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. The scope of the present invention is limited only by the scope of the following claims. The clinical usefulness of the cannabinoids, including . When THCA is heated up past approximately 220 degrees Fahrenheit, it is converted to THC. Plant pigments include chlorophyl and other carotenoids that absorb light to catalyze photosynthesis. The driving force in crystal formation is supersaturation. 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. With potencies pushing 99.9 percent - it's not hard to see why. In one embodiment, the invention includes tetrahydrocannabinols, including the most commonly known cannabinoid, tetrahydrocannabinol (THC). THCA slowly decarboxylates during storage and fermentation. 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. Abstract and Figures. 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. The SKU Options of Short Path vs. The RV 100 is a multi-use reactionary vessel designed specifically for the cannabis and hemp industries. For example, the precipitate can be removed by filtration, or by transferring the supernatant to a clean vessel. If it's 95%, that's very little of anything else 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. Glass beads were added to the beaker before putting it into an undisturbed deep freeze (75 C.). [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). The Growth factor dominates Nucleation in the equilibrium that exists between the two, and the conditions favor the formation of few, but large, crystals. 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. 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. 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. AKA THC crystals or THC diamonds are a marijuana concentrate that is in a solid form. 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. Crystals formed in between 12 hours and several days. The plant which comprises at least one cannabinoid optionally further comprises at least one terpene and/or terpenoid. In one embodiment, the present invention discloses a method for obtaining a higher purity cannabinoid solvent extract from a plant which comprises at least one cannabinoid. 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. 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. These techniques essentially separate THCA from other constituents found in cannabis. 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. The crystallization step can be performed by methods as known in the art. In general, a crude extract of cannabis can be made via solvent extraction. Cannabinoids may also occur as their pharmaceutically acceptable salts. 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. The target compound of interest, is dissolved in a specific solvent to form a solution. The crystallized THCa may be used in the acid form, or converted to the neutral form by methods known in the art. The residual filtrate, following crystallization of THCa, is relatively depleted in THCa, but will contain other cannabinoids and terpenes. It is usually found as a mixture with isocaryophyllene (the cis double bond isomer) and -humulene, a ring-opened isomer. Can Cannabinoids Interact With Other Drugs? 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. To create sauce, the extracted THCA diamonds are then recombined with the concentrate. The alternatives are to do ethanol extraction at an ambient temperature or in highly cool conditions. 6, 2015, and the disclosure is hereby incorporated by reference herein in its entirety. 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. The end product itself has many benefits, especially for those looking to solely reap the benefits of THCA without any extra compounds present. 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. When repeatedly purified using the rosin technique, THCA . In many instances, administration in conjunction with the subject products enhances the efficacy of such agents. Terpene Content: B-Myrcene, D-Limonene, B-Caryophyllene. Then it will go trough filter again and put back in the rotary evaporator to the methonal from your THCA extract. The plant may be cannabis or hemp, and the cannabinoid may be tetrahydrocannabinolic acid (THCa). Here's how they do it. When growing crystals, there are two concurrent processes that are kept in balance. Convenient formulations include tablets, capsules, oils, gels, lozenges, troches, hard candies, nutritional bars, nutritional drinks, metered sprays, creams, suppositories, transdermal patches, among others. 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. When the process is complete, crystal looks like, well, small crystals. Interested in learning how to optimize your THCa crystallization techniques? 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.

This process can reduce the number of plant pigments and waxes in the end product but . These steps are discussed hereinbelow. Methods to increase surface area for crystallization are known in the art, such as glass beads, which are optionally added prior to the crystallization. We cover how to produce quality hydrocarbon crude, and how . 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. 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. Generally, the solvent extraction step can be carried out by methods that are known in the art. Wait until the solution reaches 45 C and all the oil has dissolved. By using pressure, motion, and heat, the solvent is evaporated, leaving behind 9 tetrahydrocannabinolic acid.

That being said, if the product is heated, it becomes THC (not THCA), and it will give you a high. The present inventor has found that after two filterings, the solvent and extract are typically significantly more pure. 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. 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. In much of the chemical industry, recrystallization is used to achieve very high purity on a large scale without complex equipment. The advantage of using them lies in their near 100 percent THC content. 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. It also recommends against smoking, since heating will change THCA into THC through decarboxylation. It's fine. In another embodiment, the terpene/terpenoid includes linalool. When dried and/or heated, THCA decarboxylates and turns into THC. 2468 Industrial Row Dr | Troy, MI 48084. The crystallization pictured in this section shows purification of a roughly 1 \: \text {g} sample of old \ce {N} -bromosuccinimide (NBS), which was found in its reagent bottle . To achieve their desired taste preferences, many people combine THCA crystalline with terpenes. The present invention includes a method for obtaining a higher purity cannabinoid solvent extract from a plant which comprises cannabinoids and/or terpenes. 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. Myrcene, or -myrcene. THC whose full scientific name is delta 9 tetrahydrocannabinol is the primary psychoactive ingredient in marijuana. 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. Disclosed herein are methods for improving the purification of plant extracts via removal of undesirable impurities and, in the case of cannabis extracts, subsequent selective isolation of tetrahydrocannabinolic acid (THCa) from other cannabinoids and terpenes. 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. 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. THCa, the acid precursor to THC, was crystallized out of solution using the filtered solvent extract. Optionally, any product should have solvent thoroughly removed. 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. In another embodiment, the cannabis is frozen. 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. In one embodiment, the solvent extract filtrate is cooled to allow for crystallization of the 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. 1. Its IUPAC name is (1S,5S)-2,6,6-Trimethylbicyclo[3.1.1]hept-2-ene (()--Pinene). However, these techniques either tend to be difficult to scale and make continuous, or tend to degrade the molecules of interest. 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. It's the same way they make thca crystals, they add a shit ton of limonene, wait for crystals to form, pour out remaining solution and chunk out the crystals.
