[0049] Example 2 Preparation method of Indigo Naturalis of the present invention

[0050] (1) Take the crude indigo, put the crude indigo into the batching tank, add 20 times the amount of water, stir to form a uniform suspension slurry, and then put it in the primary sedimentation tank for coarse sedimentation for 5 minutes; pump the suspension into a first-stage spin filter In the purifier (flow rate is 2 cubic meters / hour), the mixed spinning liquid slowly rises through the 40-mesh filter membrane, and the suspension passing through the filter membrane enters the secondary rotary filter purifier through the overflow port, and the suspension continues to pass 80 mesh filter membrane, the suspension purified by the two-stage rotary filtration purifier, enters the first-stage sedimentation separation tank through the overflow; the suspension of the impermeable filter membrane, at a frequency of 30-40 minutes / time Drain into the waste pool.

[0051] (2) The suspension purified by t...

[0054] 1. Investigation of the dilution ratio and feed flow rate of crude indigo

[0055] Taking the standard under "Indigo Naturalis" in the 2010 edition of the Pharmacopoeia as an indicator, the dilution ratio and feed flow rate of crude indigo were investigated. The results are shown in Table 1.

[0056] Table 1

[0057]

[0058] It can be seen from the above table that when diluted 5 or 10 times, the production speed is faster and the finished product yield is higher, but the content of indigo and indirubin is low, which does not meet the pharmacopoeia standards; when the dilution is 15-30 times, The material flow rate is 1.5-2.5 cubic meters per hour, and the contents of indigo and indirubin are in line with the pharmacopoeia standards. When the dilution factor is more than 25 times, the production speed is slower. Therefore, the dilution factor should be preferably 15-25 When t...

Abstract

The invention provides an indigo with a high content of indirubin, and a preparation method and corresponding processing apparatus of the indigo. The indigo processing apparatus and the indigo preparation method provided by the invention can change the content of the indirubin in a product by adjusting the aperture of a filter membrane, so as to satisfy different quality requirements of the product, the operation is simple, the affects of environment and weather are avoided; the preparation method is directly applied for the standardized industrial production without operation based on the experience of a professional, and the quality of the product is stable and controllable. At the same time, the quality of the medical material is greatly improved besides the assurance of the large-scale production; the content of the main anticancer active component indirubin in the indigo is 12-25 times of that in the pharmacopeias standard; and a novel choice is provided to the medical use of the indigo and the separation, the purification and the research of the effective component.

Description

technical field [0001] The invention relates to Qingdai and its preparation method and processing equipment, belonging to the field of medicine. Background technique [0002] Indigo Daisy is the dry powder or mass obtained by processing the leaves or stems and leaves of Baphicacanthus cusia (Nees) Bremek., Polygonum tinctorium Ait., or Isatis indigotica Fort. piece. Indigo Daisy is mild in taste and cold in nature. It has the effects of clearing away heat and detoxification, cooling blood, and relieving convulsions. It is often used for febrile toxins in seasonal diseases, vomiting and hemoptysis. In recent years, it has been used for bleeding caused by bronchiectasis. Indigo and indirubin are the main components of Qingdai, among which indirubin has good anti-tumor activity, and has obvious inhibitory effect on chronic myeloid leukemia, but has no obvious inhibitory effect on bone marrow. [0003] Traditional indigo naturalis processing procedures mainly include raw mater...
