Percolation technology for parasite-expelling Vernonia esculenta Hemsl. injection

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...

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
