Abstract

The invention belongs to the technical field of traditional Chinese medicine extraction, and particularly to an ainsliaea fragrans champ extract, an extraction method and an application thereof. The ainsliaea fragrans champ extract is an ethyl acetate extract or / and a methanol extract of ainsliaea fragrans champ, and is prepared by using the following method: crushing the whole grass of ainsliaea fragrans champ, adding ethyl acetate, carrying out heating reflux extraction 2-3 times, filtering, respectively mixing the filter residues and the filtrates obtained from the two extractions, carrying out concentration drying on the filtrate to obtain the ethyl acetate extract, carrying out heating reflux extraction 2-3 times on the filter residue with methanol, filtering, mixing the filtrates obtained from the two extractions, carrying out concentration drying on the filtrate to obtain the methanol extract. The ainsliaea fragrans champ extract has anti-oxidation activity and liver protection activity.

Description

[0001] technical field [0002] The invention belongs to the technical field of extracting traditional Chinese medicines, and in particular relates to an extract of apricot and rabbit ear wind, an extracting method and application thereof. Background technique [0003] The liver is the central station of metabolism in the body and the largest and most important detoxification organ in the human body. It can maintain blood sugar concentration through glycogen synthesis, decomposition, and heterogenesis. The bile acids produced by the liver can promote the digestion and absorption of lipids and synthesize most of the plasma. protein; liver also stores fat-soluble vitamins A, D, E, K and B vitamins 12 , can swallow or swallow bacteria in the blood, aging and damaged red blood cells, viruses, antigens and denatured protein bodies, etc., purify the blood, remove the toxicity of ammonia and have hematopoietic functions. Once the liver is damaged, it often leads to various ser...
