Embodiment 1

[0024] The preparation method of this leech whole powder comprises the steps:

[0025] A. Cleaning and disinfection: wash 100kg of fresh Hirudo phenanthae with clear water to remove impurities, immerse in 50ppm chlorine dioxide aqueous solution for disinfection for 3-5min, drain and set aside;

[0026] B, beating: adding 200kg sterile water to beating together with the bilruta phenanthrene gained in step A, for subsequent use;

[0027] C. Enzymolysis: Pour the slurry obtained in step B into an enzymolysis container, add 1 kg of chitinase and 0.3 kg of collagenase, and hydrolyze it for 1 hour at a pH value of 4.0 and a temperature of 35 to 40° C. to phenanthrene The body of the leech was melted, and the temperature was raised to 90°C to inactivate the enzyme for 10 minutes;

[0028] D. To remove peculiar smell: After cooling, add 200kg of milk powder and stir evenly;

[0029] E. Drying: Use 2mol / L NaOH solution to adjust the pH value to 7, pre-cool at -20 for 240min, and then...

Embodiment 2

[0032] The preparation method of this leech whole powder comprises the steps:

[0033] A. Cleaning and disinfection: Rinse 100kg of fresh Hirudo phenanthae with clear water to remove impurities, immerse in 100ppm chlorine dioxide aqueous solution for disinfection for 3-5 minutes, and drain for later use;

[0034] B, beating: adding 200kg sterile water to beating together with the bilruta phenanthrene gained in step A, for subsequent use;

[0035] C. Enzymolysis: Pour the slurry obtained in step B into an enzymolysis container, add 1 kg of chitinase and 0.6 kg of collagenase, and hydrolyze for 2 hours at a pH value of 5.0 and a temperature of 35 to 40°C until the phenanthrene The body of the leech was melted, and the temperature was raised to 90°C to inactivate the enzyme for 10 minutes;

[0036] D. To remove peculiar smell: After cooling, add 100kg milk powder and 1kg mogroside and stir evenly;

[0037] E. Drying: Use 2mol / L NaOH solution to adjust the pH value to 7, pre-coo...

Abstract

The invention discloses a preparation method of leech whole powder and relates to the technical field of medicine. The preparation method of the leech whole powder comprises the following steps: cleaning and disinfecting fresh poecilobdella manillensis, pulping, performing enzymolysis, removing peculiar smell, drying and the like. The extraction rate of hirudin of the obtained leech whole powder reaches up to 100 percent; meanwhile, the leech whole powder contains other active components of various tissues and saliva of the leeches and is conducive to improve the anti-coagulant activity of thehirudin; the leech whole powder can have flavors of milk flavor, fruit flavor or flower fragrance, has good taste and does not have peculiar smell.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a preparation method of whole leech powder. Background technique [0002] Phnom Penh leech, Poecilobdellamanillensis, a leech family animal, is a medicinal material used by Zhuang doctors in Guangxi. Its common names are leeches, leeches, horse turtles, and water hemp sticks. (Amenorrhoea), Bainong (sore carbuncle), Mabang (stroke), twist image (sprain and contusion) and other diseases. According to literature records, this product mainly contains natural hirudin and histamine-like compounds, among which hirudin has the functions of anticoagulation, fibrinolysis, inhibition of platelet aggregation, reduction of whole blood viscosity, reduction of blood fat, and reduction of thrombus. [0003] Natural hirudin is a single-chain small-molecule acidic single-chain polypeptide with 65 or 66 amino acid residues and no glycosylation extracted from the secretion of leech salivary gland...
