Problems solved by technology

Influenza A (H1N1) is a major infectious disease that affects the national economy and people's livelihood in my country. So far, there is no specific and effective treatment
[0005] The applicant found in the research that the raw materials for the preparation of anti-hepatitis B virus (referred to as HBV virus) drugs and anti-influenza virus (referred to as A-H1N1 virus) drugs are relatively scarce and the drug efficacy is not ideal
Willow Orchid plants mainly contain polyphenols, flavonoids, triterpene acids, tannin compounds and other chemical components. Relevant research on anti-hepatitis B and anti-influenza A

Embodiment 1

[0024] Embodiments 1 to 3 are specific implementations of effective parts of willow orchid and its preparation method and application of the present invention, wherein embodiment 1 is the best embodiment.

[0025] Example 1

[0026] The preparation method comprises the steps of: pulverizing the whole willow orchid herb, ultrasonically extracting with an ethanol solution with a concentration of 75% to 85% by volume for 0.5 to 1 hour, and then filtering to obtain an ultrasonic extract and a filter residue, adding 75% to the filter residue by volume Reflux extraction with 85% ethanol solution 3 times, 0.5-1 hour each time, filter to obtain the reflux extract, combine the ultrasonic extraction and reflux extract, concentrate and dry to obtain the extract; add distilled water to disperse the extract to obtain the extract dispersion, Then use petroleum ether, ethyl acetate and n-butanol as solvents to extract the extract dispersion, take the ethyl acetate extract and the n-butanol e...

Embodiment 2

[0028] The preparation method comprises the following steps: pulverizing the whole willow orchid, ultrasonically extracting with an ethanol solution with a volume percentage concentration of 85% to 95% for 2 to 3 hours, then filtering to obtain an ultrasonic extraction solution and filter residue, and adding 85% to volume percentage concentration of Reflux extraction with 95% ethanol solution 3 times, each time for 1-1.5 hours, filter to obtain reflux extract, combine ultrasonic extraction and reflux extract, concentrate and dry to obtain extract; add distilled water to disperse extract to obtain extract dispersion, Then use petroleum ether, ethyl acetate and n-butanol as solvents to extract the extract dispersion, take the ethyl acetate extract and the n-butanol extract to evaporate the solvent respectively, and obtain the ethyl acetate part and the n-butanol part of the willow flower ; Concentrate and dry the remaining extract dispersion after extraction to obtain the aqueous...

Embodiment 3

[0030] The preparation method comprises the steps of: pulverizing the whole willow orchid herb, ultrasonically extracting with an ethanol solution with a concentration of 65% to 75% by volume for 1.5 to 2 hours, and then filtering to obtain an ultrasonic extract and a filter residue, adding 65% to 75% by volume concentration to the filter residue Reflux extraction with 75% ethanol solution twice, each time for 1.5-2 hours, filter to obtain the reflux extract, combine the ultrasonic extraction and reflux extract, concentrate and dry to obtain the extract; disperse the extract with distilled water to obtain the extract dispersion, Then use petroleum ether, ethyl acetate and n-butanol as solvents to extract the extract dispersion, take the ethyl acetate extract and the n-butanol extract to evaporate the solvent respectively, and obtain the ethyl acetate part and the n-butanol part of the willow flower .

Abstract

The invention discloses the effective parts of willow herb and the preparing method and application thereof. The invention belongs to the technical field of plant extract. The method comprises of the steps of selecting the mixture of one or two extracts from the ethyl acetate part and normal butyl alcohol part of willow herb at any weight ratio. Crushing the willow herb and adding 65%-95% (volume) ethanol solution for extraction, concentrating and drying the extracting solution to obtain the extract; adding distilled water for dispersion to obtain extract dispersion, then respectively using petroleum ether, ethyl acetate and normal butyl alcohol as the solvent to extract the extract dispersion, making the solvent volatilize to obtain the ethyl acetate part and normal butyl alcohol part of willow herb. Effective parts of willow herb can be used to prepare anti-HBV, anti-H1N1 A virus drugs, with good effect to resist hepatitis B and influenza A virus.

Description

technical field [0001] The invention relates to effective parts of willow orchid and its preparation method and application, and belongs to the technical field of plant extracts. Background technique [0002] Willow ( Epilobium angustifolium L.) is a perennial stout herbaceous plant of the Onagraceae family (Onagraceae), which is a traditional medicinal plant in Tibetan medicine. It is mainly born in forest margins, under forests and wet grasslands of river valleys at an altitude of 2800-4250 meters. Distributed in the southwest, northwest, north and northeast of China. It is widely distributed in the northern temperate zone, and it is also found in North America, Europe to Japan, Asia Minor to the Himalayas and other places. The whole herb of Willow Orchid is bitter in taste, non-toxic, and has the functions of reducing swelling and diuresis, producing breast milk, and moistening the intestines. Indications of insufficient milk, qi deficiency and edema. Geer Gesang Ta...
