Problems solved by technology

Using the traditional decoction method, it is easy to destroy its heat-sensitive components. On the other hand, the decoction of the active ingredients is not complete, resulting in the loss of active ingredients.
The preparation of astragalus into superfine powder of astragalus is beneficial to improve the utilization rate of active ingredients, but at the same time, due to the increase of powder specific surface area, it has the disadvantages of easy moisture absorption, oxidation, deterioration, etc.

Abstract

The invention relates to the technical field of Chinese medicine preparations, and in particular relates to an astragalus wall-broken preparation. The astragalus wall-broken preparation is prepared as follows: crushing astragalus into super-fine powder, then granulating by use of an ethanol-water wet method, extruding for forming at a certain rotating speed and drying, and the prepared astragalus wall-broken preparation is high in bioavailability, strong in stability, and good in disintegration.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine, in particular to a wall-broken preparation of Astragalus membranaceus. 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 of the drug increases eff...
