| titleOfInvention | Extraction of alkaloids from opium |
| abstract | Dissolving opium in a solvent, heating the dissolved opium solution, cooling the dissolved opium solution, adjusting the pH of the dissolved opium solution with at least one first weak acid, filtering the dissolved opium solution and filtering the filtrate Then extracting and purifying at least one alkaloid from opium, comprising separating and purifying at least one alkaloid from the filtrate. Preferably, this includes the further step of cooling the opium solution after adjusting the pH of the dissolved opium solution with at least one first acid. Preferred methods for separation and purification of at least one alkaloid in the filtrate include the use of preparative liquid chromatography, however, solvent extraction and filtration can also be used. |
