| titleOfInvention | Method for preparing indigo naturalis |
| abstract | The invention provides a method for preparing indigo naturalis, comprising the following steps of: a, placing leaves or stem leaves of strobilanthus (acanthaceae), indigo (polygonaceae) or woad (crucifer) into water with the pH value of 3.5-7 at the temperature of 25-60 DEG C, the mass ratio of water to the fresh leaves is 8-15, soaking for 24-48 hours, and filtering and removing leaf slag to obtain filtrate; b, introducing air into the filtrate for 0-30min, adding alkaline to regulate the pH value to be 9-10.5, introducing the air for 30-240min, adding lime milk, stirring to be uniform and standing, filtering to obtain precipitate, drying to obtain crude indigo, and refining the crude indigo to finally obtain the indigo naturalis. In the crude indigo prepared by adopting the method provided by the invention, contents of indigo blue and indirubin are higher, and product quality is good. |
