Problems solved by technology

Viruses are microorganisms parasitic in the living cells of the host. Any drug that can inhibit or kill the virus is also toxic to the host cell, which brings great difficulties to the development of antiviral drugs
In the prevention and treatment of avian influenza, there is still no ideal chemotherapy drug

Embodiment Construction

[0049] Referring to Figure 1, the preparation method is as follows:

[0050] (1) Get 1 ton of bamboo block or bamboo chips, pulverize, and dry to a moisture content of 15%;

[0051] (2) Place in a retort and heat to 180°C, conduct retort for 6 hours, and collect retort liquid;

[0052] (3) Naturally precipitate the collected dry distillation liquid for 15 days, filter, then distill under reduced pressure at 60° C. and 300 Pa vacuum for 3 hours, and collect the distillate;

[0053] (4) In the collected distillate, add ethanol in the ratio of distillate: ethanol = 4: 1 by weight, and react in the reactor for 3 hours at 160° C. and 1.2 atmospheric pressure, and separate layers , remove the generated ethyl acetate to obtain refined bamboo vinegar, add 1.0% by weight sodium bicarbonate as a stabilizer to obtain the final product, and fill it as a finished product.

[0054] The added stabilizer can also be one or more of 0.3-1.5% sodium bicarbonate, 0.5-2% sodium carbonate, and 0.2-...

Abstract

The invention relates to a bamboo vinegar extraction used for effectively removing avian and poultry influenza virus from environment such as air and soil, and for preventing avian and poultry influenza virus in eliminating environment of human and avian cross-infection and a preparation method thereof. The preparation method is divided into the steps that: the bamboo is crushed and is naturally dried or dried in other way to lead the bamboo moisture content to be 10-15 percent; then the bamboo is heated in a dry distillation reactor to raise the temperature to 150-200 DEG C for 5-7 hours to collect the bamboo vinegar liquid; the collected bamboo vinegar, after natural setting for 7-49 days, is filtrated, thereafter, the distillate liquid is collected after decompression distillation for 2-5 hours; the collected distillate liquid is added with ethanol and put into a reactor vessel for 2-4 hours under temperature of 150-180 DEG C and atmospheric pressure of 1.1-1.4; fine bamboo vinegar liquid is made by layered and removed of generated ethyl acetate. At last the final product is obtained by added with stabilizer. The invention has the advantages of convenient use, nature and environment protective and can effectively eliminate the avian and poultry influenza virus in environment.

Description

technical field [0001] The invention relates to an environmental disinfectant product and a preparation method thereof, in particular to an extract of bamboo vinegar solution for eliminating avian influenza virus in the environment which can effectively eliminate air, soil and other environments, and prevent human and poultry cross-infection. Preparation. Background technique [0002] Avian influenza is an acute and highly fatal infectious disease of poultry caused by type A avian influenza virus. Poultry such as chickens, turkeys, ducks, and quails, as well as wild birds, waterfowl, and seabirds can be infected, but chickens and turkeys are the main ones. Pigs, cats, monkeys and other animals and humans can also be infected. [0003] Avian influenza first occurred in Italy in 1878, and was historically known as fowl plague or true fowl plague. For more than 100 years, bird flu has continuously attacked the poultry industry in the whole world and directly threatened human...
