Embodiment 1 3

[0025] The preparation of embodiment 1 triterpene saponin compound

[0026] Weigh 80 kg of licorice slices, add 10 times the amount of 95% ethanol to heat and reflux to extract twice, each time for 2 hours, filter, add 10 times the amount of 50% ethanol to the dregs and repeat the extraction twice, filter, combine the extracts and decompress Concentrate until there is no alcohol smell; add appropriate amount of water to the extract to form a suspension, extract the suspension with petroleum ether and ethyl acetate; prepare the extraction residue with an aqueous solution to a certain concentration, elute through D101 macroporous resin, and first use 5 column volumes were eluted with pure water with a pH of 1-2, and then 5 column volumes were eluted with 10% ethanol with a pH of 1-2, and finally eluted with 50% ethanol with a pH of 1-2, and 50% ethanol The total licorice saponin extract was obtained by dehydration and drying (yield 4.2kg).

Embodiment 3

[0069] Example 3 Cytotoxicity test

[0070] Human hepatocyte L02 cell line was cultured in DMEM medium containing 10% (volume fraction) inactivated standard fetal bovine serum, 100 U / mL penicillin, and 100 μg / mL streptomycin at 37°C, 5% CO 2, cultivated in an incubator with saturated humidity, and passaged once every 2-3 days. Cells in logarithmic growth phase were used in the experiments. Cells in the logarithmic growth phase were taken, and after trypsinization, the cell suspension was prepared with DMEM medium containing 10% fetal bovine serum, and the cell concentration was about 1×10 5 1 / ml, inoculated in a 96-well culture plate, 180 μL per well; take the saponin compound uralsaponinI prepared in Example 1 of the present invention, respectively set 2 μM, 5 μM, 10 μM, 20 μM, 50 μM, 100 μM 6 concentrations, and then add them to each well 20 μL dimethyl sulfoxide, set 4 duplicate wells for each group, set at 37°C, 5% CO 2 After culturing in the incubator for 72 hours, add...

Abstract

The invention discloses a novel triterpenoid saponin compound with a liver protection effect. By systematically and deeply studying chemical components of liquorice, a new triterpenoid saponin compound is separated from licorice through wave spectrum and mass spectrometric data analysis. The pharmacological experimental study represents that the triterpenoid saponin compound disclosed by the invention is capable of obviously reducing CCl4 induced liver injury model mice, ethanol induced liver injury model mice, D-galactosamine induced liver injury model mice serum ALT (alanine aminotransferase), AST (aspartate amino transferase) activity and liver tissue MDA (methylene dioxyamphetamine) content and enhancing liver SOD (superoxide dismutase) activity, and the compound has an obvious protection effect on the liver injury; the toxicity test study represents that the triterpenoid saponin compound with the liver protection effect, which is disclosed by the invention, has no obvious toxicity, and can be hopefully developed as a novel medicine or healthcare product with liver protection effect.

Description

technical field [0001] The invention relates to a compound, in particular to a new triterpene saponin compound with hepatoprotective effect extracted from traditional Chinese medicine licorice and its application in the preparation of hepatoprotective medicine or health care product, belonging to the technical field of medicine. Background technique [0002] The liver is one of the most important organs in the human body, and liver disease is a relatively common clinical disease. Therefore, liver disease has always been one of the key research objects of medical science. Liver injury is a pathological state with outstanding characteristics shared by many liver diseases, which seriously threatens human health. Various harmful factors such as drugs, viruses, alcohol, organisms, etc. may cause liver function to be damaged to varying degrees, thereby reducing liver detoxification, excretion function, reserve and regeneration capacity, reducing liver blood flow, and aggravating ...
