Method for extraction and purification in multiple active substances and dyes from solid matrix as leaves, roots, seeds, involves using supercritial carbon dioxide and seeds of urucum for extracting via supercritial technology

NOVELTY – The method involves using supercritial carbon dioxide and seeds of urucum for extracting through supercritial technology and fractionation or purification, where extractor and fractioning unit are in series, and a nontoxic and inert solvent is used. The method has no contact with oxygen to avoid degradation of carotenoids and extraction is made at certain temperatures. USE – Method for extraction and purification in multiple active substances and dyes from solid matrix as leaves, roots, seeds. ADVANTAGE – The method ensures low-cost and does not generate waste of organic solvent.

Main Application Field

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).)
