| titleOfInvention | PROCEDURE FOR THE PURIFICATION AND STABILIZATION OF STREPTOMICINE |
| abstract | The present invention relates to a process for the purification and stabilization of streptomycin, which consists in that 100 volumes of streptomycin solution, which has been discolored with bromine and charcoal water according to known procedures, is passed through a ion-exchange resin chromatography column type Amberlite IR 45 or IR 93SF to obtain a pH of 5.8 ... 6.3 and then treat at room temperature with 1 ... 10 parts by weight of one of the stabilizing substances chosen from the sodium EDTA in admixture with sodium metabisulphite, boric acid or sodium citrate in a ratio of 1 ... 10: 1, sodium salt of EDTA as such, sodium bisulfite or rangalite, and finally nipagin stability preservatives: nipasol in a weight ratio of 3: 1 and in an amount of 1: 1 to 20 parts by weight. |
