Medicine material specification dividing and production place processing method of Rheum tanguticum Maxim. ex Regel

Abstract

The invention relates to a medicine material specification dividing and production place processing method of Rheum tanguticum Maxim. ex Regel. The medicine material specification dividing and production place processing method comprises the following steps of: carrying out Rheum tanguticum Maxim. ex Regel medicine material specification classification, slicing, drying and the like. The rank division method to which the invention relates is simple and accurate, different ranks of medicine materials have an obvious quality and ingredient content difference, and the rank division method can be used for guiding enterprises to purchase different specifications of Rheum tanguticum Maxim. ex Regel on the market according to requirements. The Rheum tanguticum Maxim. ex Regel optimized by the invention has a simple and reasonable processing method and a clear parameter and is convenient in practical production, the content of the relevant medicinal components of the Rheum tanguticum Maxim. ex Regel can be effectively improved, and technical support is provided for normalized production of Rheum tanguticum Maxim. ex Regel medicine material decoction pieces.

Description

technical field [0001] The invention belongs to the field of commodity specification classification of Chinese medicinal materials and processing of Chinese medicinal materials, and relates to a method for classification of medicinal material specifications of Tangut rhubarb and processing methods of origin. [0002] technical background [0003] Rheum tanguticum Maxim.ex Regel is a plant of the genus Rhubarb in the family Polygonaceae. Its growth environment is mostly high altitude and cold climate areas, and it is mostly planted in Gansu, Qinghai, Sichuan and other places. Tangut rhubarb, rhubarb palmatum and medicinal rhubarb are the basic plants of rhubarb, a traditional Chinese medicine. The long-term practice of traditional Chinese medicine and modern clinical experiments have proved that Tangut rhubarb has the functions of purging accumulation, clearing heat and purging fire, cooling blood and detoxifying, removing blood stasis and dredging menstruation, promoting damp...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many and confusing ways to classify the specifications of different medicinal materials of Rhubarb Tangut on the market, and at the same time, there is no strong basis (only the "Chinese Pharmacopoeia" 2020) stipulates that the diameter of the medicinal materials should not be less than 3cm), so different parts and different specifications of medicinal materials are often mixed, resulting in the same The content of batches of medicinal materials is uneven, and the quality uniformity is difficult to guarantee

[0005] In order to reduce the drying time of the medicinal materials during processing, the Tangut rhubarb is usually sliced ​​thinner, which is not conducive to the accumulation of medicinal ingredients; when the medicinal materials are dried, the drying temperature is mostly based on the experience of the farmers or workers Depending on the situation, the lack of scientific basis is also not conducive to the accumulation of medicinal ingredients, and ultimately makes it difficult for companies to meet the content requirements of relevant departments when selling or exporting Tangut rhubarb in the market, and the products lack competitiveness.
