Cannabidiol Phytocannabinoid Extraction

Introduction Cannabis sativa L. or marijuana, is a flowering plant that has been used for millennia for food, drugs (both legal and illegal), textile (hemp), and religious purposes. Selective breeding has resulted in numerous C. sativa strains (cultivars) with different properties. For example, hemp strains are fibrous and low in cannabinoids, while medicinal strains are highly flowering and contain both phytonutrients and phytochemicals. Bioactive compounds can be extracted from oils or as aqueous phases from seeds, flowers, leaves, and stems using traditional techniques such as cold-pressing and solvent extraction or by contemporary procedures like ultrasound. Supercritical fluid extraction with carbon dioxide (SFE-CO2) is another technology used in industry to extract p...
