Embodiment 1

[0026] Preparation method: Take the coarse powder of the round leaves of Shanxiang, use 50% ethanol as the extractant, soak it for 24 hours, then carry out percolation at a speed of 7ml / kg / min, collect 11 times the percolation liquid of the medicinal material, recover the ethanol, and depressurize Concentrate to a thick paste or dry to obtain the ethanol percolation extract of Shanxiang round leaves.

Embodiment 2

[0028] Preparation method: take the round leaf powder of Shanxiang, use 60% ethanol as the extractant, soak for 48 hours, percolate at a speed of 2ml / kg / min, collect 9 times the amount of percolation liquid of medicinal materials, recover ethanol, and depressurize Concentrate to a thick paste or dry to obtain the ethanol percolation extract of Shanxiang round leaves.

Embodiment 3

[0030] Preparation method: take the coarse powder of the round leaves of Shanxiang, use 65% ethanol as the extractant, soak for 48 hours, and percolate at a speed of 5ml / kg / min, collect 8 times the percolation liquid of the medicinal material, recover the ethanol, and depressurize Concentrate to a thick paste or dry to obtain the ethanol percolation extract of Shanxiang round leaves.

Abstract

The invention relates to a turpinia arguta seen leaf ethanol diacolation extract, which is used for preparing medicines for preventing and curing flu complications including kidney failure. The extract is obtained by means of extracting turpinia arguta seen in an ethanol diacolation manner. The ethanol diacolation extracting method includes steps of taking turpinia arguta seen leaf coarse powder; using 25-90% of ethanol as extractant; performing diacolation at the speed ranging from 1ml / kg / minute to 18ml / kg / minute after steeping for 12 hours to 72 hours; collecting diacolation liquid with volume 4-9 times of that of medicines; recycling the ethanol; and decompressing and concentrating the diacolation liquid to obtain thick paste or drying the diacolation liquid to obtain the turpinia arguta seen leaf ethanol diacolation extract.

Description

technical field [0001] The present invention relates to an ethanol percolation extract of Cymbidium saponifolium and its preparation method and application. Background technique [0002] At present, influenza virus is becoming more and more serious, and influenza virus is closely related to respiratory diseases and systemic diseases caused by it. my country is one of the countries with high incidence of influenza. Not only has a large population, but also living habits are conducive to the transmission of influenza virus. The average number of episodes ranged from 0.3 to 0.7, and 2 to 4 in key groups. Influenza poses a serious threat to human beings, especially the emerging strains of influenza virus, which not only cause secondary infections of other microorganisms, but also directly lead to organ damage and allergic reactions leading to death. But there is no effective method and treatment means for treating influenza virus and its disease (influenza) at present, such as t...
