Embodiment 1

[0029] The preparation method of the new compound in embodiment 1, the little flower Qingfengteng

[0030] (1) Take the dried herb, add 12 times the concentration of 70% ethanol, reflux and extract three times for 3 hours, 2 hours, and 2 hours respectively, filter, combine the extracts, and concentrate under reduced pressure until there is no alcohol smell , get the extract;

[0031] (2) Take the extract of step (1) and add ethanol to make the alcohol content 20%, remove the insoluble matter by centrifugation, and obtain the supernatant.

[0032] (3) Get the supernatant that step (2) obtains and absorb through HP-20 type macroporous resin column (medicinal material: resin=1:2 adsorption), first use 30% ethanol-water eluting 5 column volumes, obtain stream Fraction 1; Fraction 2 was obtained by eluting with 50% ethanol-water for another 5 column volumes, concentrating and drying. Fraction 2 was subjected to 200-300 mesh silica gel column chromatography, and the mixture of dic...

Abstract

The invention belongs to the technical filed of medicine, and discloses a compound in sabia parviflora and a preparation method and an application thereof. The compound is 2-methyl-2-hydroxymethyl-5,6-dihydroxy-7-(3-methyl-3-hydroxy-1-butenyl)-1H-indene-1-ketone-3-O-glucoside. The preparation method of the compound is simple, and obtain the pure compound through separation. The experiment shows that the compound can obviously reduce the hepatocyte triacylglycerol content and caspase3 activity due to aliphatic acid, increases the MDA content, reduces hepatocyte apoptosis rate, and can be usedfor preventing non-alcoholic fatty liver damage. The invention provides the application of the compound in preparation of medicines for treating non-alcoholic fatty liver damage.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a compound in Qingfengteng and its preparation method and application, especially the application in the preparation of medicine for treating non-alcoholic fatty liver injury. Background technique [0002] Nonalcoholic fatty liver disease (NAFLD), also known as nonalcoholic fatty liver disease and pseudoalcoholic liver disease, is a clinicopathological syndrome with liver histological changes similar to alcoholic liver disease but without a history of excessive drinking. Changes with the progression of the disease showed simple fatty liver, steatohepatitis, fatty liver fibrosis and liver cirrhosis. With the global prevalence of obesity and related metabolic syndrome, non-alcoholic fatty liver disease has become an important cause of chronic liver disease in developed countries such as Europe and the United States and in wealthy areas of my country. The prevalence of ...
