Amazing stuff. Apparently we are on Cannabinoid no 182. We will never stop learning about this fascinating plant and her compounds. #knowingisgrowing
182 and counting. Two scientists found an unusual cannabinoid in hemp for the first time. The study is a preprint, but the two authors used a selective method of separating compounds called flash chromatography. Doing so allegedly prevented the loss of water during analysis. Dr. E. Michael Thurman and Imma Ferrer found a form of CBD with a double-bond missing from the methylene group between the eighth and ninth position. The compound instead contains an additional hydroxyl (OH) group, which means this is a hydrated variant of CBD. [Remember: Hydration ≠ Hydrogenation] The authors identified the compound as epiCBD-hydrate. Although, it’s difficult to tell how the compound would affect humans without biological tests. CBD, as a molecule, contains two major portions: The limonene half and the olivetol piece. The ‘limonene half’ of CBD is responsible for quinone formation and the eventual purple color formation. This newly identified form of hydrated CBD has an olivetol piece and an a-terpineol half. The team used flash chromatography to find the compound in hemp cultivars from Boulder, Colorado. They employed liquid chromatography coupled to quadrupole time- of-flight mass spectrometry (LC/Q-TOF-MS) to analyze the exact mass of the compound. The authors also used tandem mass spectrometry and NMR to identify epiannabidiol-hydrate in hemp. As far I understand - normal procedures induce enough heat to break the bond holding onto the +OH group, which leaves behind a hydrogen atom with an extra electron (H-). | [OH + H = H2O] The freed electron moves into the molecule. The position of the rearranged ion essentially destroys the original cannabinoid (epiCBD-hydrate) and forms a different isomer of CBD. The paper noted that they found other isomers and COOH analogues in various hemp products. Did hydration simply occur in the experiment, given the use of water in the mobile phase? Or does this preprint document the authentic discovery of a hydrated cannabinoid from multiple hemp samples? I am not a chemist or engineer myself, so please leave a comment if you have better insight >>>
