| titleOfInvention | Technological method for extracting 1-deoxynojirimycin from mulberry leaf |
| abstract | The invention relates to a technological method for extracting 1-deoxynojirimycin from mulberry leaves, which is a technological method for extracting and separating 1-deoxynojirimycin with content being more than 70 percent from mulberry leaves. The technological method comprises the following steps of: conducting water extraction and alcohol precipitation on mulberry leaves, removing impurities by using macroporous resin, enabling mulberry leaf alkaloid to be enriched by cations, conducting gradient elution through silica gel column chromatography, and conducting vacuum drying to finally obtain the 1-deoxynojirimycin product. The technological method provided by the invention has the advantages that the technological process is simple, the obtained product does not contain residual organic solvent, the fillers for silica gel column chromatography are low in cost and can be repetitively used, the cost is reduced, special equipment is not needed in the entire technological process, the operation is simple and feasible to conduct and the technological method is very suitable for industrial production. |
