Problems solved by technology

[0002] At present, when the insect repellent Vernonia injection is manufactured, the medicinal materials are prepared by using the percolation process, but the current percolation process only soaks the medicinal materials during work, and it is easy to cause the medicinal materials to percolate incompletely during the percolation process. Causes waste of medicinal materials and affects the use efficiency of medicinal materials

Embodiment Construction

[0014] In order to deepen the understanding of the present invention, the present invention will be described in further detail below with reference to the embodiments, which are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0015] The present embodiment provides a percolation process for anthelmintic Vernonia injection, and the percolation process steps are as follows:

[0016] Step 1: Weigh the crushed medicinal materials, and mix the medicinal materials for later use;

[0017] Step 2: Put the medicinal materials into the bucket, add ethanol to immerse the medicinal materials and let them stand;

[0018] Step 3: Place the medicinal materials after standing in the percolation tank, place pressing plates on the bottom and top of the percolation tank, clamp and compress the medicinal materials through the pressing plates, add ethanol for the second time, immerse the medicinal materials, and let ...

Abstract

The invention provides a percolation technology for a parasite-expelling Vernonia esculenta Hemsl. Injection. The percolation technology comprises the following steps: 1, weighing a crushed medicinalmaterial, and mixing the medicinal material for later use; 2, placing the medicinal material in a container barrel, adding ethanol to immerse the medicinal material, and standing the medicinal material and the ethanol; 3, placing the standed medicinal material in a percolation pot, placing compacting plates at the bottom and the top of the percolation pot, clamping and compacting the medicinal material with the compacting plates, adding ethanol again to immerse the medicinal material, and standing the medicinal material and the ethanol; 4, percolating the medicinal material through the percolation pot, and recovering the obtained percolate; and 5, filtering the percolate to remove impurities, and heating the filtered percolate. The percolation technology adopts the weighing, immersion, percolation, recovery and heating processes to obtain the parasite-expelling Vernonia esculenta Hemsl. Injection, and the ethanol is supplemented into the percolation pot during the percolation in orderto fully percolate the medicinal material, so the percolation efficiency of the medicinal material is improved, and the working time of the percolation technology is shortened, thereby the productioncost is reduced.

Description

technical field [0001] The invention relates to the field of preparation of traditional Chinese medicine injections, in particular to a percolation process of an anthelmintic Vernonia injection. Background technique [0002] At present, in the manufacture of Vernonia vernonia injection, the percolation process is used to prepare the medicinal materials. However, the current percolation process only soaks the medicinal materials during operation, which is prone to unfinished percolation of the medicinal materials during the percolation process. It causes waste of medicinal materials and affects the efficiency of medicinal materials. Therefore, it is particularly important to solve the problem of insufficient utilization of medicinal materials in the percolation process of Vernonia vulgare injection. SUMMARY OF THE INVENTION [0003] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a percolation process of...
