| titleOfInvention | Process for obtaining laxative compounds from senna drugs |
| abstract | The present invention provides a process for obtaining laxative compounds from senna drug, wherein n (a) the senna drug is extracted with aqueous methanol by countercurrent percolation and the extract concentrated at a temperature of ≦50° C. until the methanol has been completely removed from the extract; n (b) the extract obtained is purified by continuous liquid-liquid extraction with an organic solvent; n (c) the refined material (raffinate) obtained is transferred to a crystallization apparatus, acidified, while stirring, to a pH of 1.5 to 2.0, seeded with sennoside crystals, left to crystallize while stirring and the crystalline crude sennoside obtained separated off; n (d) whereafter, the crude sennoside are, if desired, recrystallized and optionally converted with a pharmacologically compatible base into a pharmacologically compatible salt. |
