| titleOfInvention | The method for preparing indigo and indirubin by using fresh leaves of maltose |
| abstract | The invention discloses a method for preparing indigo and indirubin by using the fresh leaves of the blue horse blue. Yuhong purification; (5) chromatographic column separation and purification. The present invention does not add lime to let it settle, but directly replaces it with adsorption resin. The adsorption effect is better than that of calcium carbonate; the process flow is simplified, the removal of impurities by calcium carbonate is omitted, and it can be directly eluted and purified by column; the resin can be recycled and reused, and the purity of the obtained indirubin and indigo yield is higher than that of the conventional process. |
