Embodiment 1

[0024] Take 100g of Achyranthes bidentata medicinal material, pulverize and add 15 times the amount of ethanol and ether mixed solution for reflux extraction (the volume ratio of ethanol and ether is 1:9) for 30 minutes, recover ethanol and ether, filter to obtain medicinal residue, add medicinal residue Extract with 10 times water, decoct for 30 minutes, collect the filtrate after filtration, concentrate to a relative density of 1.15 (80°C) under the conditions of a temperature of 80°C and a vacuum of 0.06MPa, and add the same volume of a mixed solution of chloroform and n-butanol (The volume ratio of chloroform and n-butanol is 5:1), the white flocculent precipitate is removed, and the water layer is concentrated to a relative density of 1.23 (80°C) under the conditions of a temperature of 80°C and a vacuum of 0.06MPa. Knee extract 21g.

Embodiment 2

[0026] Take 100g of Achyranthes bidentata medicinal material, crush it and add 10 times the amount of ethanol and ether to reflux extraction (the volume ratio of ethanol and ether is 1:9) for 40 minutes, recover the ethanol and ether, filter to obtain the medicinal residue, add the medicinal residue Extract with 20 times water, decoct for 20 minutes, filter, collect the filtrate, concentrate to a relative density of 1.12 (80°C) under the conditions of a temperature of 70°C and a vacuum of 0.06MPa, and add the same volume of a mixed solution of chloroform and n-butanol (The volume ratio of chloroform and n-butanol is 5:1), the white flocculent precipitate is removed, and the water layer is concentrated to a relative density of 1.20 (80°C) at a temperature of 80°C and a vacuum of 0.06MPa to obtain a soil cow Knee extract 23g.

Embodiment 3

[0028] Take 100g of Achyranthes bidentata medicinal material, pulverize, add 30 times the amount of ethanol and ether mixed solution to reflux extraction (the volume ratio of ethanol and ether is 1:9) for 20 minutes, recover ethanol and ether, filter to obtain medicinal residue, add medicinal residue Extract with 40 times water, decoct for 40 minutes, filter, collect the filtrate, concentrate to a relative density of 1.13 (80°C) under the conditions of a temperature of 80°C and a vacuum of 0.06MPa, add the same volume of a mixed solution of chloroform and n-butanol (The volume ratio of chloroform and n-butanol is 5:1), the white flocculent precipitate is removed, and the water layer is concentrated to a relative density of 1.22 (80°C) at a temperature of 80°C and a vacuum degree of 0.04MPa to obtain a soil cow Knee extract 19g.

Abstract

The invention relates to the technical field of medicines, in particular to an extraction method for an achyranthes aspera extract. The achyranthes aspera extract obtained through the extraction method can be used for preparing a medicine for treating alcoholic hepatitis. The achyranthes aspera extract provided by the invention can effectively treat alcoholic hepatitis.

Description

Technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to an extraction method of Achyranthes bidentata extract. Background technique [0002] Alcoholic hepatitis is a liver disease caused by long-term heavy drinking. Severe alcoholism can induce extensive liver cell necrosis and even liver failure. The disease is one of the common liver diseases in my country. Seriously endanger people's health. Alcoholic hepatitis is also a clinical type of alcoholic liver disease. It is a group of clinicopathological syndromes caused by massive necrosis of liver cells in a short period of time. It can occur with or without cirrhosis, mainly manifested by elevated serum ALT and AST. And serum total bilirubin was significantly increased, which may be accompanied by fever and increased peripheral blood neutrophils. Severe alcoholic hepatitis refers to the manifestations of liver failure in patients with alcoholic hepatitis, such as blood coagu...
