| titleOfInvention | The preparation method of astragalus root total saponin extract |
| abstract | The present invention provides a kind of preparation method of improved astragalus root total saponin extract, including carries out water of alcohol precipitation twice to the Aqueous extracts of the Radix Astragali and sink, and reuses macroporous resin adsorption three times, astragalus root total saponin extract is produced after concentration.Because astragalus root total saponin content is relatively low, and medicinal material contains a large amount of glucides, extracts separation relatively difficult.The present invention can significantly reduce invalid impurity content, remain the active ingredient of medicine, drastically increase sample purity, and then improve the recovery rate of saponin(e, astragalus root total saponin content is up to 98~100% in astragalus root total saponin extract made from this method, is a kind of extraction separation method of effective astragalus root total saponin. |
