Method for processing poecilobdella manillensis lesson

Abstract

The invention discloses a method for processing a poecilobdella manillensis lesson, comprising the following specific steps: washing and drying the poecilobdella manillensis lesson, adding water in 2-5% of the poecilobdella manillensis lesson by weight, and freezing at a temperature of -20 DEG C for 3 h-5 h till the poecilobdella manillensis lesson is frozen to obtain a material a; using a beaterto evenly beat the material a into pulp to obtain a material b; placing the material b in a freeze-drying tray, freeze-drying at a gradient at a temperature of -50-45 DEG C for 40 h-60 h, and conducting condensation and dehydration to obtain a freeze-dried oecilobdella manillensis lesson powder c; and crushing the freeze-dried oecilobdella manillensis lesson powder c at a low temperature and sieving to obtain the oecilobdella manillensis lesson processed from the target. The invention solves the problem of antithrombin activity reduction at a high temperature, while the blood is retained in the body of the oecilobdella manillensis lesson, so as to avoid the problem of antithrombin activity reduction due to drainage of the blood in the body of oecilobdella manillensis lesson, which may retain the active ingredients in the oecilobdella manillensis lesson to the utmost extent. The processing is simple and convenient, the production conditions is easy to control, the product quality is well controllable, and the processing is suitable for large-scale production and promotion.

Description

technical field [0001] The invention belongs to the technical field of medicinal material processing, and in particular relates to a processing method of Hirudo phenantha. Background technique [0002] Poecilobdella manillensis (Poecilobdella manillensis) is a blood-sucking leech, commonly known as Phnom Penh leech. It is the dried whole body of Poecilobdella manillensis, a species of Hirudidae. . There are records in "Famous Doctors", "Shen Nong's Materia Medica Collection", "Materia Medica", "Tang Materia Medica", "Compendium of Materia Medica" and other herbal medicines. "Tang Materia Medica" states, "There are leeches and grass leeches. The big ones are about a foot long, and those with blood in the abdomen are better to dry." [0003] Hirudo phenaridis is mainly distributed in Guangxi, Guangdong, Hainan, Fujian and other provinces, and lives by sucking the blood of vertebrates such as humans, livestock, and frogs in the natural environment. Hirudo phenanthrene has si...

Problems solved by technology

If the living body of Hirudo phenanthae is directly scalded to death, the antithrombin activity in the body will be reduced due to high temperature; if the blood stored in the body of Hirudo phenanthae after death is not drained, the activity of antithrombin will also be reduced; If it is dried at low temperature and powdered at room temperature, the antithrombin activity will also be reduced

[0007] In summary, the disadvantages of the processing method of Hirudo phenatus in the prior art are: during the processing such as scalding to death, storing blood, drying and pulverizing, the active ingredient, i.e. hirudin, is greatly reduced, which directly affects the quality of Hirudo phenatus.
