Embodiment 1

[0072] This example discloses the use of supercritical CO 2 The extraction method prepares the Ainaxiang extract, specifically:

[0073] Take an appropriate amount of coarse powder of Ainaxiang (Blumea balsamifera (L.) DC.) and place in CO 2 In the supercritical extraction device, 95% ethanol is used as an entrainer, and its consumption is 6 times that of the raw material (volume / mass, when the mass is g, the volume is mL).

[0074] The extraction temperature is 45.0°C and the extraction pressure is 22.0MPa; the temperature of the first separation tank is 50.0°C and the pressure is 6MPa; the temperature of the second separation tank is 50.0°C and the pressure is 5MPa; the extraction time is 120min. The obtained product is evaporated to ethanol, and the extract of Ai Naxiang is obtained, and its total flavonoid content is 28wt%.

Embodiment 2

[0076] This example discloses that the present invention adopts the cold soaking method to prepare the extract of Ai Naxiang (B. balsamifera (L.) DC.) raw material coarse powder, and add 95% according to the ratio of material to liquid: 1:20 ethanol, cold soaked for 48 hours, filtered, collected the filtrate, and evaporated the ethanol to obtain the Ainaxiang extract, whose total flavonoid content was 24wt%.

Embodiment 3

[0078] This example discloses that the present invention adopts the ultrasonic extraction method to prepare Ai Naxiang extract, specifically: take an appropriate amount of Ai Naxiang (Blumea balsamifera (L.) DC.) raw material, extract twice, and add 20 times the amount of 95% each time Ethanol, sonicated at room temperature for 60 minutes and then filtered, the filtrate was collected, and the ethanol was evaporated to obtain the extract of Ai Naxiang, whose total flavonoid content was 19wt%.

Abstract

The invention belongs to the technical field of medicines, and particularly relates to a blumea balsamifera extract with an anti-influenza virus effect and a preparation method of the blumea balsamifera extract. The blumea balsamifera extract is an ethanol extract of blumea balsamifera, and the mass percentage content of total flavonoids in the extract is greater than or equal to 18.56% and less than or equal to 38.48%. According to the preparation method of the blumea balsamifera extract, blumea balsamifera is taken as a raw material, 50-95% ethanol is taken as a solvent, and the blumea balsamifera extract is extracted by adopting a supercritical CO2 extraction method, a cold soaking method, an ultrasonic extraction method, a cold soaking and ultrasonic extraction method, a percolation method and a reflux method. The invention unexpectedly discovers that the blumea balsamifera ethanol extract has the effect of resisting multiple influenza viruses. Experiments show that the blumea balsamifera ethanol extract has a good inhibition effect on influenza A virus and influenza B virus.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to an extract of Ainaxiang with anti-influenza virus effect and a preparation method thereof. Background technique [0002] Ainaxiang is the leaves and twigs of Ainaxiang in the family Asteraceae. It has the functions of expelling wind and dampness. It has a long history of medicine in minority areas such as Li, Miao, and Zhuang. It is an important folk medicine. At the same time, Ainaxiang is also one of the important sources of obtaining Ai tablets. [0003] Ainaxiang is rich in volatile oil components, and the utilization of this drug in the prior art is also mostly based on volatile oil components. For example, the application number is 200810044799.9 patent "extracted by Zingiber officinalis and Ainaxiang, containing 1,8-cineole and ainaxiang oily composition and its use", which discloses the The oily substance extracted from Heinaxiang, and its application in o...
