Extraction of plant products with supercritical glycerin

By Scott Jenkins |

Construction is underway of a prototype system designed to extract natural bioactive product compounds from plants using supercritical glycerin as the extraction solvent. The initial target for the process is to extract cannabidiol (CBD), tetrahydrocannabinol (THC) and other active compounds from Cannabis sativa plants. “Most processes using supercritical fluids — such as carbon dioxide — to extract plant products end up with highly viscous products that are difficult to work with,” explains inventor Demetri Hopkins. “The glycerin concentrates generated from this system can be used directly in a range of products, and allow standardized concentrations of the target compounds.” The intellectual property behind Hopkins’ glycerin extraction technology has been exclusively licensed to incubator platform ECO Innovation Group Inc. (Van Nuys, Calif.; www.ecoig.com), and the prototype is being fabricated by high-pressure equipment specialist Fluitron Inc. (Ivyland, Pa.; www.fluitron.com). While glycerin (propane-1,2,3-triol) is used as the supercritical extraction solvent, the process depends on a set of proprietary co-factors required to maintain glycerin in a supercritical state, and that promote the efficient dissolution…
