Rhizoma coptidis piece processing and comprehensive utilizing method

Abstract

The invention belongs to the technical field of traditional Chinese medicine processing and particularly relates to a rhizoma coptidis piece processing method. Mainly a new choice is provided for rhizoma coptidis piece processing. The method includes the following steps of harvesting, crude cleansing, dewatering, refined cleansing, slicing, drying and screening, and rhizoma coptidis decoction pieces are obtained, and leftovers obtained during cutting of the rhizoma coptidis pieces are comprehensively utilized. The method can be used for processing rhizoma coptidis pieces and rhizoma coptidis on the producing area, the method is high in industrialization degree, energy is saved, and the content of total alkaloids in the obtained rhizoma coptidis decoction pieces is higher than that of total alkaloids in rhizoma coptidis decoction pieces obtained through a traditional method by 10% or above.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine processing, and in particular relates to the production and comprehensive utilization technology of Coptis chinensis tablets. Background technique [0002] Coptis chinensis is bitter in taste, cold in nature, and has the functions of purging fire, detoxifying, clearing away heat, and drying dampness. For dysphoria, confusion, upset and insomnia, hot and humid fullness, vomiting, abdominal pain and diarrhea, conjunctival congestion and swelling, sore tongue, eczema, burns, vomiting blood, epistaxis, etc. Coptis chinensis was first recorded in "Shen Nong's Materia Medica", which clearly stated that the efficacy of Coptidis chinensis is "improving eyesight, clearing the intestines" and treating "abdominal pain, diarrhea" and gynecological diseases. Since "Shen Nong's Materia Medica", Chinese medicine monographs of all dynasties have specialized discussions: In the late Eastern H...

AI Technical Summary

Problems solved by technology

The main problems of the traditional Coptis chinensis production process: ①, Coptis chinensis is dried twice, energy consumption is very high; ②, when Coptis chinensis is soaked in water again, because the active ingredient of Coptis chinensis Coptidis alkaloids is water-soluble components, it will inevitably lead to the loss of active ingredients. Therefore, the alkaloid content of the decoction pieces obtained by traditional techniques is about 10% lower than that of Tonglian ("Chinese Pharmacopoeia" 2010 edition); ③. It is easy to "drop slag" (fragments), and the yield of Coptis chinensis is low. If the watering time is too long, the loss of alkaloids will be greater; ④, during the drying process of Coptis chinensis, cracks will appear in the internal dehydration, and the cracks will appear when slicing after watering again Will not close, resulting in cracks in the middle of Coptis chinensis, and the color deepens, affecting the appearance

The main disadvantages of this process are: ①. Before the raw material of Coptis chinensis is dried, the fibrous root is "soft" and cannot "knock off" the fibrous root, so it must be dried; "Through", there is a pair of contradictions, care about one and lose the other

②. Coptidis decoction pieces are processed with “cleaning with water” and “moisturizing”. How to control the loss of active ingredients and ensure moistening is difficult to master. Therefore, the loss of active ingredients is inevitable, but the difference is the amount of loss

This method utilizes the characteristic that the active ingredients of Coptidis fresh products do not lose when washed, and removes sediment by washing, which is innovative, but there are still deficiencies: ① Coptis chinensis has a large number of fibrous roots. It is very difficult to remove the silt, and washing to remove the silt requires labor and equipment, which increases investment and cost; ②After the fresh Coptis chinensis is cleaned and processed, when it is directly sliced, because the fresh Coptis chinensis contains a lot of water (70-90%), the slicer It is necessary to press the fresh Coptis chinensis first, and then cut it with a blade. When pressing, it is easy to squeeze out the Coptis chinensis juice, resulting in the loss of some active ingredients; ③The water content of fresh Coptis chinensis after cleaning is high, and it is easy to slip when directly sliced, which affects the work of the slicer Efficiency etc.
