Embodiment 1

[0075] Take 1Kg of the coarse powder of Eupatorium adenophorum above ground, extract three times at room temperature, 24 hours each time, the amount of ethanol is 8L, 6L and 6L respectively, combine the filtrate, recover the solvent under reduced pressure until dry, and obtain the extract of Eupatorium adenophorum. The rate is 5.0%, and the total flavonoid content is 21.3%.

Embodiment 2

[0077] Get Eupatorium adenophorum 30-40cm near top stem and leaf coarse powder (toxin composition dehydroeuplenone content is 0.39%) 100g, spray 0.5% liquid compound microorganism (main bacterial classification is Lactobacillus plantarum, Bacillus subtilis, Bacillus licheniformis, Lactobacillus acidophilus) airtight treatment after detoxification agent detoxification agent for three days, dry to obtain Eupatorium adenophorum detoxification herb powder (toxin component dehydroeuplenone content is reduced to 0.011%), methanol ultrasonic extraction under room temperature three times, Each time 30 minutes, the amount of methanol used three times is 300mL, the filtrates are combined, and the solvent is recovered under reduced pressure to dryness to obtain the extract of Eupatorium adenophorum with a yield of 7.3% and a total flavonoid content of 19.8%.

Embodiment 3

[0079] Take 200g of the aerial part of Eupatorium adenophorum in the flowering stage, add distilled water, heat and reflux extraction three times, each time for 2 hours, the amount of distilled water is 1.6L, 1.2L and 1.2L respectively, combine the filtrate, recover the solvent under reduced pressure to a small volume, freeze-dry , to obtain the extract of Eupatorium adenophorum with a yield of 14.6% and a total flavonoid content of 25.5%.

Abstract

The invention relates to application of eupatorium adenophorum spreng or a eupatorium adenophorum spreng extract in preparation of a veterinary medicine for treating respiratory system diseases or preparation of a medicine for enhancing the immunity. The treatment on the respiratory system diseases comprises inflammation diminishing, cough relieving, phlegm elimination and flu or infectious bronchitis treatment. The invention further relates to application of the eupatorium adenophorum spreng or the extract thereof in preparation of a feed additive for livestock. The application realizes effective development and utilization of the eupatorium adenophorum spreng, turns the harm into a benefit, and has great economic and social significance.

Description

technical field [0001] The invention relates to the application of the plant Eupatorium adenophorum, in particular to the application of the plant Eupatorium adenophorum or its extract in the preparation of veterinary medicine or health-care feed additive. Background technique [0002] Eupatorium adenophorum Spreng belongs to Compositae. It is a perennial, clustered evergreen semi-shrub, commonly known as airplane grass and devil's grass. Originally produced in Mexico, South America, it was introduced into Yunnan, my country from Myanmar and Thailand in the 1940s, and began to cause weeds in my country in the 1970s. At present, Eupatorium adenophorum has been widely distributed in Yunnan, Sichuan, and Guizhou, and its biomass is huge in the hardest-hit areas, but so far there is no effective control system. Effective development and utilization of Eupatorium adenophorum, turning harm into benefit, has great economic and social significance. [0003] In recent years, Sichua...
