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 antithromb...

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.

Example Embodiment

[0030] Example 1
[0031] Wash the philippines leeches with flowing purified water by spraying, wash and dry, then add 2% water of the philippines leeches by weight, and then freeze them at a temperature of -20°C for 3h until freezing to obtain material a; use material a The beating machine is homogenized to form a slurry to obtain material b; the material b is placed in a freeze-drying tray, and the temperature is -50℃~45℃ for gradient freeze-drying, after condensation and dehydration, Philippine leeches freeze-dried powder c is obtained; The dry powder c was pulverized at 10° C. at low temperature and passed through a 50-mesh sieve to obtain the target processed Philippine bull leech. The gradient temperature stage of gradient freeze-drying consists of 12 temperature stages, specifically -50℃~-40℃ temperature stage 5h, -40℃~-35℃ temperature stage 3h, -35℃~-20℃ temperature stage 6h, -20 ℃~-15℃ temperature stage 3h, -15℃~-5℃ temperature stage 3h, -5℃~0℃ temperature stage 3h, 0℃~8℃ temperature stage 6h, 8℃~15℃ temperature stage 6h, 15℃ ~25℃ temperature stage 3h, 25℃~30℃ temperature stage 3h, 30℃~35℃ temperature stage 3h, 35℃~45℃ temperature stage 5h.
