Traditional Chinese medicine hemsley rockvine root processing method capable of keeping pharmaceutical-effect active ingredient

Abstract

The invention discloses a traditional Chinese medicine hemsley rockvine root processing method capable of keeping a pharmaceutical-effect active ingredient. The traditional Chinese medicine hemsley rockvine root processing method comprises the following steps: selecting fresh hemsley rockvine roots and washing; preliminarily drying the washed hemsley rockvine roots at a temperature being 55-75 DEGC under a nitrogen-gas atmosphere, removing water left after washing on the surface, and taking out after cooling; cutting off bad parts, and cutting the residual parts into slices with thicknesses being 1.5-3.5 mm; primarily drying hemsley rockvine root slices at a temperature being 60-70 DEG C, preliminarily drying for 15-25 minutes under nitrogen-gas atmosphere, and taking out after cooling; putting the preliminarily dried hemsley rockvine root slices into a drying and refrigerating room to refrigerate to 3-7 DEG C; adopting a quick freezing technology for freezing the refrigerated hemsleyrockvine root slices to a temperature being -25 DEG C to -125 DEG C within 3-35 minutes, blowing dried non-oxidative gas to the surfaces of frozen hemsley rockvine root slices, and further drying until moisture content is 1.4-2.9%. The drying technology, the freeze-drying technology and the gas-flow drying technology are comprehensively applied, and the atmosphere, the temperature and the time are controlled in each step, so that the retention effect of the traditional Chinese medicine active ingredient is greatly improved in a drying process.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine processing, in particular to a processing method of traditional Chinese medicine trefoil that retains medicinal active ingredients. Background technique [0002] Clover is the root or whole plant of Cliff Cliff vine in the family Vitis genus, also known as golden thread hanging gourd, silk thread hanging golden bell, three-leaf flat rattan, stone mouse, small flat rattan, stone monkey, soil classics Pills, three-leaf pairs, one-grain beads, etc., are mainly produced in Jiangsu, Zhejiang, Jiangxi, Fujian, Taiwan, Guangdong, Guangxi, Hubei, Hunan and other places. Its medicinal records were first seen in "Compendium of Materia Medica", which is called "Sanyegan climbing vine, bitter, pungent, cool in nature, clearing heat and cooling blood, promoting blood circulation and expelling wind". Clover is recorded in "National Chinese Herbal Medicine Compilation", "Chinese Medicine Chronicles",...

AI Technical Summary

Problems solved by technology

This process improves the retention of medicinal active ingredients to a certain extent by rationally configuring parameters such as time, temperature, and pressure of vacuum freezing. However, a large amount of medicinal active ingredients are still lost during the drying process.

In addition, the large investment and high energy consumption of vacuum freeze-drying equipment lead to high production costs and limit the application of the technology to a certain extent.

[0008] One of the common usages of the traditional Chinese medicine Clover is decocted with water, but in the process of decocting with water, a large amount of active ingredients are either lost due to evaporation, or destroyed due to high temperature, oxidation and other reasons. 3-5% of the medicinal active ingredients are decocted in water, and a large amount of medicinal active ingredients are wasted

Another method is to make oral preparations, but the most critical steps of pulverization and wall breaking in the preparation process need to be manually ground, which has poor wall breaking effect and high cost; and the drug effect may be caused by excessive local temperature during the grinding process. Active ingredient lost or destroyed
