Embodiment 1

[0026] Embodiment 1: extract and isolate C from hairy chicory 15 h 18 o 5 English name 11B, the method of 13-Dihydrolacurin, proceed as follows:

[0027] a, the chicory root is dried in the air, and the moisture content is 1%, and the dried chicory root is taken, soaked for 36h with 3 times the amount of 60%% ethanol;

[0028] b. Adopt the percolation method, the ratio of chicory root and 60% ethanol is 1:10, flow rate: 1ml / min, and collect the percolation liquid;

[0029] c. The percolate is filtered once with a mesh with a pore size of 0.1 mm, and the filtrates are combined;

[0030] d. Use a vacuum distillation device, at a pressure of 1×10 -3 kPa, temperature: at 30°C, distill off ethanol to obtain a thick extract of 0.1g / ml;

[0031] e. Mix the thick extract and water at a ratio of 1:2 to obtain a mixed solution, extract with ethyl acetate equal to the volume of the mixed solution, separate the ethyl acetate layer, and distill and concentrate at a pressure of 0.1 MPa...

Embodiment 2

[0043] Embodiment 2: extract and isolate C from hairy chicory 15 h 18 o 5 English name 11B, the method of 13-Dihydrolacurin, proceed as follows:

Abstract

The invention relates to a method for separating and extracting C15H18O5 from Cichorium glandulosum Boiss.et Hout and use of C15H18O5 the English name of which is 11B, 13-Dihydrolacurin. The method is characterized by comprising the following steps: soaking the root of Cichorium glandulosum Boiss.et Hout by ethanol; collecting the percolate by a percolation method; obtaining a thick extract by a reduced pressure distillation device; passing the extract through a silicagel column, an octadecylsilyl column and a Sephadex LH-20 column; eluting; and drying the eluant by the reduced pressure distillation device to obtain dry powder which is the monomer C15H18O5, the English name of which is 11B, 13-Dihydrolacurin. The compound has the effect of preventing anti-hepatic fibrosis, namely, the compound inhibits activating and proliferating effect of hepatic stellate cells, so that the C15H18O5 with the English name of 11B, 13-Dihydrolacurin can be used as a lead compound for preventing anti-hepatic fibrosis.

Description

technical field [0001] The invention relates to a method for extracting C 15 h 18 o 5 , the English name is 11β, the method of 13-Dihydrolacurin and the use of the compound. Background technique [0002] Chicory root is the root of Cichorium glandulosum Boiss, alias chicory, French chicory, blue lettuce, etc., and the scientific name CichoriumintybusL is a 2-year-old or perennial perennial plant of the genus Cichorium in the family Asteraceae. Its young leaves, leaf balls or roots Edible or medicinal. It is native to the Mediterranean, Central Asia and North Africa, and is widely cultivated in Europe. In Europe, chicory is often used as a substitute for vegetables, pasture feed, sugar raw materials and coffee. Mainly distributed in my country's Xinjiang, Shandong, Inner Mongolia and other places. Chicory is a commonly used medicinal material of the Uyghur and Mongolian. It is called Kashenna in the Uyghur language. There is a record in the national standard of medicin...
