Abstract
A method for extracting at least one alkaloid from opium that includes 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 to recover a filtrate; and then separating and purifying at least one alkaloid in the filtrate. Preferably, this includes an additional step of chilling the opium solution after adjusting the pH of the dissolved opium solution with at least one first acid. The preferred method for separating and purifying at least one alkaloid in the filtrate includes utilizing preparative liquid chromatography, however, solvent extraction and filtration can also be utilized.
