VERFAHREN ZUR ISOLIERUNG VON MUTTERKORNALKALOIDEN AUS KULTURSUSPENSIONEN. |
摘要 |
A process for isolating ergot alkaloids from culture suspensions, in which after mechanical filtration, the residue is dried in a fluidized drying bed and the alkaloids are extracted with an aprotic organic solvent, reextracted with a weakly acidic aqueous solution which is subsequently made basic, and finally extracted with a water-immiscible organic solvent, from which the alkaloids are isolated in a conventional manner. In certain instances, the culture suspension is stirred with an adsorbent clay to entrain the water-soluble alkaloids. |
