Abstract

The present invention relates to uses of a turpinia ternate leaf ethanol reflux extract in preparation of drugs for neuraminidase inhibition, wherein the turpinia ternate leaf ethanol reflux extract is prepared by adding ethanol to turpinia ternate leaves and carrying out extraction. The concrete extraction method comprises: taking turpinia ternate leaves; adding 40-85% ethanol in a Turpinia arguta/ethanol (W/V) ratio of 1:5-13) to carry out reflux extraction 2-3 times, wherein each reflux extraction is performed for 1-2.5 hours; filtering; mixing the obtained filtrates; and carrying out reduced pressure concentration to obtain a thick paste or drying to obtain the turpinia ternate leaf ethanol reflux 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...
