| titleOfInvention | A method of obtaining thebaine from the roots of Papaver bracteatum |
| abstract | The object of the invention is to provide thebain innlarge amounts for codeine synthesis.nIt is an object of the present invention to provide an inexpensiventhe way of obtaining thebaine from the roots of Papavernbracteatum. According to the invention, it is extractednundried comminuted root material.nThis is made possible by the amount of thebainencontained in the roots of Papaver bracteatum,nwhich remain after maturing of plants innor after harvest, during storagenpractically does not change without drying.nThe extraction is carried out with aqueous acidsnand organic solvents miscible withnwater. Thebain is extracted from this extractnin a known manner. In particular, the following is suitablena variant of the invention where it is groundnthe root material is extracted with hydrochloric acidnand simultaneously treated with chloroform. |
