Pure Chinese medicine anti-avian influenza air disinfectant and its preparation method

Abstract

The invention relates to a Chinese medicinal preparation used as air disinfectant, more particularly to a herbal air disinfectant for controlling avian influenza and a preparation method thereof. The herbal air disinfectant for controlling avian influenza is prepared from the following materials in weight ratio: 1-10 parts of Hypericum perforatum, 1-10 parts of Scutellaria baicalensis, 1-10 partsof Isatis indigotica root, 1-10 parts of Lonicera japonica flower, 1-10 parts of Pogostemon cablin and 1-10 parts of Eupatorium fortunei. The air disinfectant is produced by the following steps: mixing the above herbal materials, decocting in water for 1-3 times (boiling for 2-3 hours for each time), collecting volatile oils and decoctions, mixing the decoctions, standing overnight, collecting supernatant, filtering, concentrating, precipitating with ethanol, removing ethanol, diluting with water, stirring, standing, collecting supernatant, filtering, adding the volatile oils, adjusting the concentration of drug liquid to 4-10% of the raw materials, stirring and packaging. According to the technical proposal mentioned above, the air disinfectant has no irritation and toxicity, can efficiently kill various pathogenic microorganisms, particularly avian influenza virus, and is used for the prevention and treatment of avian influenza.

Description

technical field [0001] The invention relates to a traditional Chinese medicine air disinfectant, in particular to a traditional Chinese medicine air disinfectant against bird flu and a preparation method thereof.

Problems solved by technology

However, each has certain defects, such as toxicity, irritation, metal corrosion, and poor lasting effect; many of them constitute pollutants themselves, which affect human health to varying degrees, and are not suitable for human environments; all personnel must leave the field during disinfection, and operate The system must have protective measures; after disinfection, the odor cannot be eliminated quickly, and long-term use will cause the danger of accumulated poisoning to the human body, etc.
