Embodiment 1

[0018] The present embodiment provides a kind of preparation method of Houttuynia cordata injection for animals, it comprises the following steps:

[0019] S1. Purification: Wash the fresh Houttuynia cordata, remove the sediment, impurities and corrupted and defective Houttuynia cordata, transfer it to the medicine cutting room after filtering the water, and chop it for later use. It is best to use potable or purified water for elutriation.

[0020] S2. Soaking: Stir 2000 parts by weight of fresh Houttuynia cordata purified by S1 with a mixer to obtain Houttuynia cordata paste.

[0021] S3. Distillation: transfer the Houttuynia cordata paste prepared in S2 to the extraction tank, inject 2 times the weight of fresh Houttuynia cordata into pure water to soak it all, cover the top cover, and turn on the interlayer steam heating after soaking for 2 hours , The internal vacuum of the extraction tank is 0.2MPa. After heating to boiling, turn on the condensed water to keep the medic...

Abstract

The invention discloses a preparation method of a heartleaf houttuynia herb injection for livestock. Fresh heartleaf houttuynia herbs are used as raw materials of the heartleaf houttuynia herb injection for livestock. The preparation method comprises the steps of cleaning the heartleaf houttuynia herbs, crushing and stirring 2000 parts by weight of the heartleaf houttuynia herbs to obtain heartleaf houttuynia herb paste, adding pure water, performing soaking, sequentially performing distillation, second-time redistillation and third-time redistillation through a negative pressure distillationtechnique to obtain 1000ml of distillate, adding sodium chloride, benzyl alcohol and polysorbate-80, performing uniform mixing, performing filtration, performing encapsulation and performing sterilization so as to obtain the heartleaf houttuynia herb injection. The preparation method is simple in production technology and low in distillation temperature, the defects that effective components are oxidized because heartleaf houttuynia herb injection produced from fresh heartleaf houttuynia herbs is long in time consumption and high in distillation temperature in the prior art can be overcome, and the production cost of products is effectively reduced.

Description

technical field [0001] The invention relates to a preparation method of Houttuynia cordata injection for animals, in particular to a method for preparing Houttuynia cordata injection for animals using fresh whole herb of Houttuynia cordata. Background technique [0002] Houttuynia cordata is a herbal medicine included in the Chinese Pharmacopoeia. It belongs to the wild herb of the genus Houttuynia officinalis. The whole herb is used as medicine, tastes pungent, cold in nature, and returns to the lung meridian. It has the effects of clearing away heat and detoxification, reducing swelling and treating sores, diuresis and dehumidification, clearing away heat and stopping dysentery, invigorating the stomach and eliminating food. Accumulated heat, etc. Houttuynia cordata injection is obtained by distillation from a single fresh whole herb of Houttuynia cordata. It has strong antibacterial effect on hemolytic streptococcus, staphylococcus aureus, catarrhal coccus, pneumococcu...
