    When the supercritical CO 2 is pumped into the system, the mixture travels up the column and begins to separate the mixture. After the separation column, there are three collection vessels. As with the initial extraction, CBD, Δ 8 THC, and Δ 9 THC are separated out by precipitation. The precipitation occurs from dropping the P and T in steps from high to low.

    Pure THC and CBD Extractions, Using CO2 and Chromatography

    This patent utilizes purification in the process – this is how CBD, Δ8 THC, and Δ9 THC are separated from each other. As described above, chromatography is the mechanism of separating molecules. This can be done by columns packed with silica, and other packing materials. In chemistry, the packing materials are called purification media.

    Abattis Bioceuticals has announced the successful completion of experiments utilizing column chromatography for cannabinoid hrpalmoilmachine experiments assessed the feasibility of applying the technology for the extraction of CBD, THC and THCA from industrial hemp and cannabis.

    Pure CBD Isolation is hard, but heres a simple step-by-step

    Now that I think about it, it would be simple to isolate CBD with preparative (or adapted analytical) TLC. If you use hexane as the mobile phase and silica plates as the stationary, you can see the two bands, THC being just below CBD. You can then scrape out the CBD band, soak the CBD band in some solvent and evap.

    Those fractions (THC, CBD, and Terpenes) can then be recombined for a recipe, or signature oil which can be used for concentrates (edibles) or vape pens. The new technique is called Flash Chromatography.

    CBD Isolation from Hemp - hrpalmoilmachine

    Crystallisation is a key step in CBD isolation. After chromatography is used to refine CBD to very high levels, removing THC, terpenes and other impurities, the CBD is further purified and collected in solid form by crystallising it from the extract. This is typically done with strong solvents which help remove the THC which stays liquid.

    Flash Chromatography in Cannabis Purification | Terpenes and

    Reversed-phase chromatography, in general, is used when cannabis compounds with very different effects and applications, like THC and CBD, have travelled through the silica stationary phase with roughly the same speed and, as a result, haven’t separated enough in the column. When it comes to CBD concentrates which are intended to be non-intoxicating, even a small amount of THC is enough to compromise the final product.

    How can I rapidly remediate THC from CBD in my hemp extract

    How can I rapidly remediate THC from CBD in my hemp extract using flash column chromatography? Tetrahydrocannabinol, aka THC, is a hallucinogen found in cannabis and, to a lesser degree, in hemp. Though THC is legal in some locations in the US and Canada, there is a growing market for its non-hallucinogenic cousin, cannabidiol (CBD), which has purported medical benefits.

    Part 1: Potency Testing. Separating out the THC and CBD from the diverse soup of compounds contained in your marijuana is essentially like looking for a few needles in a big haystack. Chromatography is the chemist’s way of sorting out that haystack. In the cannabis world, potency is tested by liquid chromatography or gas chromatography.

    Figure 1. Structures of THC and CBD. To get an idea on how complex a real extract is I first tried reversed-phase flash chromatography using a 12 g C18 cartridge (Biotage® SNAP Ultra C18) and a Biotage® Isolera system. As these compounds are quite hydrophobic I chose a mobile phase gradient high in organic solvent (MeOH). The gradient started at 80% methanol in water and ended at 90% methanol.
