Method for purification of acarbose |
| abstract |
The present invention relates to a novel process for the preparation of acarbose. Said process comprises the steps of: 1) acidifying a fermentation broth containing an acarbose; 2) removing particulates from the fermentation broth; 3) adsorbing the acarbose on a cation-exchanger in the presence of an anion of a weak acid; 4) eluting the acarbose from the cation-exchanger with at least one of hydrochloric acid and the weak acid; 5) precipitating the acarbose with a solvent; and 6) separating the acarbose. |
