preparation example Construction

[0021] The present invention provides a kind of preparation method of coptis powder with high alkaloid content, the preparation method of the product of the present invention is:

[0022] Fresh Coptis chinensis is cleaned and sorted, dried and sliced, fibrous roots removed, soaked in jujube water, and then freeze-dried and crushed to obtain Coptis chinensis powder. The details are as follows:

[0023] Cleaning: Quickly wash away impurities such as surface sediment with clean water.

[0024] Sorting: graded according to the size of fresh Coptis chinensis, based on the maximum circumference of Coptis chinensis, the maximum circumference ≥ 16cm is the high grade, 8≤ the maximum circumference < 16cm is the middle grade, and the maximum circumference < 8cm is the small grade .

[0025] Drying: Put the large, medium and small fresh Coptis chinensis into the steam interlayer oven respectively, and dry them for 8-11 hours, 12-16 hours, 17-26 hours to 60% to 90% dry at a temperature o...

Embodiment 1

[0046] Take 30kg of fresh Coptis chinensis, wash it with water; divide it into large, medium and small grades according to the maximum circumference of Coptis chinensis; put them in a steam interlayer oven at a temperature of 80°C, and dry them until they are 70% dry; use a roller slicer to cut Coptis chinensis into 6mm Use a drum machine to rotate the Coptis chinensis slices to remove impurities such as fibrous roots and silt; according to the weight ratio, jujube: coptis = 1:5, jujube: water = 1:150, weigh drinking water and jujube, and boil for 2 hours , concentrated into a concentrated solution with a solid content of 10%; added to Coptis chinensis, infiltrated until the jujube liquid was sucked dry; the infiltrated Coptis chinensis was vacuum freeze-dried in stages to obtain freeze-dried Coptis chinensis, and pre-frozen for the first time Stage -30°C, 4h; second stage -50°C, 3h; third stage -60°C, 2h; vacuum drying first stage -10°C, vacuum 0.3MPa, 5h; second stage 5°C, va...

Embodiment 2

[0048] Take 30kg of fresh Coptis chinensis, wash it with water; divide it into large, medium and small grades according to the maximum circumference of Coptis chinensis; put them into steam interlayer ovens at a temperature of 70°C, and dry them until they are 80% dry; use a flaker to cut Coptis chinensis into 5mm pieces Use a drum machine to rotate the Coptis chinensis slices to remove impurities such as fibrous roots and silt; according to the weight ratio of jujube: Coptidis=1:3, jujube: water=1:100, take drinking water and jujube, boil for 1.5 hours, concentrate It is a concentrated solution with a solid content of 15%; add it to Coptis chinensis slices, soak until the jujube liquid is sucked dry; the subsequent steps are the same as in Example 1.

Abstract

The invention relates to the technical field of traditional Chinese medicines, in particular to a preparation method of high-content coptis chinensis powder. Coptis chinensis powder is prepared by sorting, drying, slicing and fibrous root removing of coptis chinensis, soaking with jujube water, pre-freezing and vacuum drying, and crushing. The rhizoma coptidis powder obtained by the preparation method provided by the invention overcomes the problems of high ash content, more scorched parts, low alkaloid content and the like of rhizoma coptidis powder obtained by a traditional process, and the obtained rhizoma coptidis powder is high in alkaloid content, high in yield and good in taste.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicines, in particular to a preparation method of high-content Coptis chinensis powder. Background technique [0002] Coptis chinensis, a traditional Chinese medicine, is the rhizome of Coptis chinensis, Coptis triangularis or Yunlian, a perennial herb of the family Ranunculaceae. The above three kinds are called Weilian, Yalian and Yunlian respectively. Coptis chinensis is cultivated in multiple lines and is produced in the central and southern provinces of my country. Sichuan and Yunnan have the largest yields. They are excavated in autumn, fibrous roots and silt are removed, and dried. Coptis chinensis is very bitter, but it has a very wide range of application value, and its medicinal value is also very high. It is a kind of cold medicinal material, which has the effect of clearing away heat and dampness, detoxifying and treating sores. According to modern pharmacological resear...
