Extraction of indol alkaloids and alkaloid fractions by supercritical fluids consists of simplified purification with reduction of the use of organic solvents in medicines production
NOVELTY – The extraction of indol alkaloids and alkaloid fractions by supercritical fluids comprises controlled production of enriched foodstuffs, medicines and therapeutics based on vegetable matter. It reduces the use of organic solvents and the complexity of product purification, and increases e.g. anti-tumor and anti-inflammatory activity. USE – In industrial chemistry.
Main Application Field
B04 (Natural products and polymers. Including testing of body fluids (other than blood typing or cell counting), pharmaceuticals or veterinary compounds of unknown structure, testing of microorganisms for pathogenicity, testing of chemicals for mutagenicity or human toxicity and fermentative production of DNA or RNA. General compositions.); B02 (Fused ring heterocyclics.); D13 (Other foodstuffs and treatment – including preservation of food, milk, milk products, butter substitutes, edible oils and fats, non-alcoholic beverages, artificial sweeteners, food additives and animal feed (A23B-L).); J01 (Separation – including evaporation, crystallisation, solvent extraction, chromatography, dialysis, osmosis including drying gases and/or vapours, and separation of solids from gases, liquids and other solids. Isotope separation, filter materials (including molecular sieves for separation), and centrifuges (except where used for analysis) (B01D, B03, B04, B07B).)
