| titleOfInvention | The method of lawsone is prepared from Lawsonia inermis |
| abstract | The invention discloses a kind of method preparing lawsone from Lawsonia inermis, step is: 1, with the powder of Lawsonia inermis plant for raw material, add extraction reagent, after mixing, soak, then supersound extraction; Centrifugal or/and solids removed by filtration residue, obtain extracting solution; Extracting solution pH is regulated to be neutral; 2, extracting solution joins in macroporous adsorption resin chromatography post, makes lawsone be adsorbed in macroporous adsorbent resin; 3, the impurity on macroporous adsorbent resin is removed; S4, with lawsone under 50 ~ 80% aqueous ethanolic solution eluting solvent wash-outs; After S5, removing ethanol, lyophilize obtains lawsone powder.The present invention adopts supersound extraction, macroporous adsorbent resin separation and purification, decompression and solvent recovery and Freeze Drying Technique, by controlling every processing condition, obtains high yield pulp1, highly purified lawsone dried powder product.This invention flow process is simple, workable, pollutes little, is applicable to suitability for industrialized production. |
