AI Technical Summary

Problems solved by technology

Relatively sensitive to temperature, poor thermal stability
Therefore, if the traditional decocting method is adopted, on the one hand, it is easy to destroy its active ingredients, and on the other hand, the incomplete decoction of the ingredients will cause the loss of active ingredients.
The preparation of Duyiwei into Duyiwei superfine powder is beneficial to improve the utilization rate of active ingredients, but at the same time, due to the increase of the specific surface area of ​​the powder, it has the disadvantages of easy moisture absorption, oxidation, deterioration, etc.

Abstract

The invention relates to the technical field of Chinese herbal preparations, specifically to a wall-broken Lamiophlomis rotata preparation. The wall-broken Lamiophlomis rotata preparation is prepared by crushing Lamiophlomis rotata into ultrafine powder, then carrying out ethanol-water wet granulation, carrying out extrusion forming at a certain rotating speed and then carrying out drying. The prepared wall-broken Lamiophlomis rotata preparation has high bioavailability, good stability and good disintegration performance.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine, and more specifically, to a unique wall-breaking preparation. Background technique [0002] Ultrafine pulverization technology is a new technology developed rapidly in recent years. Most of the active ingredients in Chinese herbal medicines are distributed in the cells. Conventional decoction pieces can only release part of the active ingredients, and the utilization rate of active ingredients is 10-30%. However, using the wall-breaking crushing technology, such as crushing Chinese herbal medicine pieces to 300 mesh About 86.7% of the cell wall breaking rate will increase the dissolution of the active ingredients in the medicinal materials, greatly enhance its efficacy, and the utilization rate of the active ingredients will be above 90%, so as to reduce the amount of medicinal materials used and protect the medicinal materials resources. The quality increases the efficacy. However, ...
