Abstract

The invention relates to an application a turpinia formosana Nakai leaf ethanol backflow extract used for preparing the medicament for preparing and treating influenza and complications, wherein the complications indicate the injury of the spleen or/and lung injury, and the turpinia formosana Nakai leaf ethanol backflow extract is prepared by adding ethanol into turpinia formosana Nakai leaf, and extracting. The specific extraction method is as follows: taking the turpinia formosana Nakai leaf, adding 40%-85% of ethanol with the volume being 5-13 times that of the turpinia formosana Nakai leaf, extracting for 2-3 times in a backflow manner for 1-2.5 hours each time, and filtering; and merging filtrates, reducing the pressure, and concentrating the filtrate to be a thick paste, or drying to obtain the turpinia formosana Nakai leaf ethanol backflow extract.

Description

technical field [0001] The present invention relates to an ethanol reflux extract of syringa rotundum 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 treating the...
