Embodiment 1

[0060] 1. Take the fresh leaves of the Acanthaceae plant, after being selected and rinsed in a cleaning tank to remove impurities and silt, put them in 30°C water, where the water volume: fresh leaf mass (L: kg) is 15, soak for 60 hours, filter to remove the leaf residue, and obtain the filtrate.

[0061] 2. Pass compressed air (at a pressure of 0.6Mpa) into the filtrate for 40 minutes, and remove the generated foam while passing the air.

[0062] 3. Add milk of lime and stir to beat indigo. The milk of lime is made by adding water with quicklime by conventional methods in the field. The amount of quicklime is 0.5% of the mass of fresh leaves. Leave it to stand and filter to obtain rough indigo. The rough indigo is then sprayed with water and dried at 50°C. , smashed into Qingdai.

Embodiment 2

[0067] 1. Take the fresh leaves of the Acanthaceae plant, after being selected and rinsed in a cleaning tank to remove impurities and silt, put them in 30°C water, where the water volume: fresh leaf mass (L: kg) is 15, soak for 60 hours, filter to remove the leaf residue, and obtain the filtrate.

[0068] 2. Pass compressed air (at a pressure of 0.6Mpa) into the filtrate for 40 minutes without removing the foam.

[0069] 3. Add milk of lime and stir to beat indigo. The milk of lime is made by adding water with quicklime by conventional methods in the field. The amount of quicklime is 0.5% of the mass of fresh leaves. Leave it to stand and filter to obtain rough indigo. The rough indigo is then sprayed with water and dried at 50°C. , smashed into Qingdai.

Embodiment 3

[0071] 1. Take the fresh leaves of the Acanthaceae plant, after being selected and rinsed in a cleaning tank to remove impurities and silt, put them in 30°C water, where the water volume: fresh leaf mass (L: kg) is 15, soak for 60 hours, filter to remove the leaf residue, and obtain the filtrate.

[0072] 2. Pass compressed air (at a pressure of 0.6Mpa) into the filtrate for 40 minutes, and remove the generated foam while passing the air.

[0073] 3. Add lime milk and stir to beat indigo. Lime milk is made by adding quicklime and water using conventional methods in the field. The amount of quicklime is 1.0% of the fresh leaf mass. Leave it to stand and filter to obtain rough indigo. The rough indigo is flown in water and dried at 50°C. , smashed into Qingdai.

Abstract

The invention relates to a processing method of baphicacanthus cusia/ polygonum tinctorium/ isatis indigotica stem/leaf processed substances. The method comprises the following steps: taking plant tissue of at least one of baphicacanthus cusia, polygonum tinctorium and isatis indigotica, performing soaking in water, and performing filtering to obtain a first filtrate, wherein the plant tissue comprises stems and/or leaves; performing one or combination of heating, ultrasonic treatment and compressed air introduction on the first filtrate to obtain a second filtrate; and adding lime milk or an alkaline solution into the second filtrate, performing the treatment of making ripe indigo seedlings into finished products of indigo, performing standing and solid-liquid separation treatment to obtain crude indigo, and enabling the crude indigo to be subjected to refining of powder and water, drying and smashing to obtain baphicacanthus cusia/ polygonum tinctorium/ isatis indigotica stem/leaf processed substances. According to the processing method, the lime dosage in processing of the baphicacanthus cusia/ polygonum tinctorium/ isatis indigotica stem/leaf processed substances is remarkably reduced, the total ash content of the prepared baphicacanthus cusia/ polygonum tinctorium/ isatis indigotica stem/leaf processed substances is remarkably reduced, and the pH value of a sample water layer is close to neutral.

Description

technical field [0001] The invention relates to the technical field of processing and processing of traditional Chinese medicines, in particular to a method for processing Qingdai. Background technique [0002] Indigo Daisy is the dry powder or pellet obtained by processing the leaves or stems of Baphicacanthus cusia (Nees) Bremek., Polygonum tinctorium Ait., or Isatis indigotica Fort. lumps or granules. It has the effects of clearing heat and detoxifying, cooling blood and eliminating spots, purging fire and relieving convulsions; it is mostly used as a medicinal raw material for warming toxins and spots, vomiting blood heat, coughing up blood in chest pain, aphtha, mumps, sore throat, and convulsions in children. [0003] The traditional processing of Qingdai mainly includes three steps: soaking the stems and leaves of raw plants, beating indigo, and refining with water. For specific steps, see figure 1 . The processing process is mainly to convert precursors such as in...
