Problems solved by technology

Chinese patent CN101785793A discloses that Antrodia Antrodia Capsules (the contents of which are solid-cultured Antrodia Antrodia extracts) from Shansheng Biotechnology Co., Ltd. can alleviate chronic hepatitis induced by carbon tetrachloride. In this finding, no statement is made about the method of Antrodia Antrodia extraction and the capsules used. Fingerprint, also unknown main components
Due to the scarcity of medicinal materials, the research and reports on the hepatoprotective pharmacological activity of wild and basswood-cultured Antrodia camphorata fruiting bodies are limited. understudied
Although the research on the hepatoprotective effect of Antrodia camphorata has received extensive attention, the chemical components with pharmacological activity and their mechanism of action have not yet been fully elucidated.

Embodiment 1

[0033] Embodiment 1, the separation and purification of triterpenoid Antcin K in Antrodia camphorata

[0034] 1. Experimental materials and methods.

[0035] All chemical reagents mentioned in this method were purchased from Beijing Chemical Plant.

[0036] First take 500 g of dried Antrodia camphorata fruiting body cultured on a plate and pulverize into coarse powder, divide into two batches, and use 6L 95% ethanol to reflux extract each batch for 6 times, each time for 3 hours; combine the extracts and rotary steam under reduced pressure to obtain about 200 g of total extract; After the total extract was suspended in 4 L of water, it was extracted 5 times with 4 L of petroleum ether successively, and the aqueous phase was extracted 5 times with ethyl acetate; the combined extract was evaporated to dryness to obtain about 132 g of the ethyl acetate layer.

[0037] About 130g of the extract from the ethyl acetate layer was separated through a silica gel column (200-300 mesh, Qi...

Abstract

The invention discloses a triterpenoid AntcinK and liver-protecting activity and application thereof. The triterpenoid AntcinK is extracted from wild, basswood-cultured and / or plate-cultured antrodia camphorate sporocarps, multiple activity screenings prove that the triterpenoid has the outstanding activity of protecting acute hepatitis liver damage caused by CCl4 and the activity of protecting abnormal lipid accumulation induced by alcohol. The compound has the remarkable preventing and treating effect on acute hepatitis, liver damage and alcoholic fatty liver and can be widely applied to liver protecting drugs and health-care products.

Description

technical field [0001] The invention relates to an extraction and separation method of antrodia antrodia triterpenoid Antcin K, and a new drug application of the compound as a liver-protecting drug, in particular to its application in protecting acute liver damage caused by acute hepatitis and protecting alcoholic fatty liver. Background technique [0002] Antrodia camphorata (Antrodia camphorata, Antrodia cinnamomea), also known as antrodia camphorata, camphor mushroom, camphor mushroom, camphor mushroom, blood ganoderma, camphor mushroom, red Antrodia camphorata, camphor fungus, red camphor sol, etc., is a kind of A rare fungus that parasitizes camphor trees unique to Taiwan, China. Antrodia cintrodia was first reported in 1990. At present, it is generally believed that Antrodia cintrodia belongs to the kingdom Fungi, Basidiomycota, Homobasidiomyeetes, Aphyllophorales, Polyporaeeae, and Thylobacteria Genus (Antrodia). It has been widely used as an anti-cancer, liver prot...
