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.
