Problems solved by technology

It has been reported in the literature that C. chinensis has the pharmacological activity of preventing and treating hepatitis and protecting the liver, but so far there has been no report on the active ingredients of C. chinensis on the prevention and treatment of ischemia-reperfusion liver injury and chemical liver injury.
In addition, the "Gansu Granules" series of Ganhuangcaocheng prescription preparations currently in clinical use, because the production process is still the traditional water extraction and alcohol precipitation, the active ingredients are not fully enriched, and they are mostly used in clinical adjuvant treatment of liver diseases, so further research is needed. improvement

Embodiment 1

[0030] The preparation of embodiment 1 macrocyclic polyphenol compound

[0031] Take 30kg of root vegetables, crush them, add 10-15 times of water to decoct twice, each time for 2 hours, combine the extracts, concentrate under reduced pressure (60°C) to get the crude extract (relative density is 1.12-1.18), centrifuge ( 5000rpm / min), to obtain 3.5kg of precipitated parts. Take 3.0 kg of the precipitated part, add 3.0 kg of 100-200 mesh silica gel, perform silica gel column chromatography, use dichloromethane: methanol (50:1-0:1) gradient elution, and detect through TLC (silica gel thin layer plate), 13 fractions were obtained (Fr 1 -Fr 13 ). Merge Fr 10 and Fr 11 Two parts, concentrated, suspended in water and centrifuged (5000rpm / min), subjected to MCI-CHP 20P gel column chromatography, gradient elution with methanol: water (1:9 ~ 1:0), after TLC (silica gel thin layer plate ) detection, get 10 fractions (Fr 1 -Fr 10 ). Fraction Fr 8 Segmented by a reverse-phase sil...

Abstract

The invention provides an application of pinocembrin dihydrogen chalcone-7-O-[3'-O-galloyl-4',6'-hexahydroxydiphenodicarboxy]-beta-D-glucoside in preparation of a liver protection medicine. The penthorum chinense pursh macrocyclic polyphenol monomer namely pinocembrin dihydrogen chalcone-7-O-[3'-O-galloyl-4',6'-hexahydroxydiphenodicarboxy]-beta-D-glucoside has a liver protection effect, can be used for preventing and treating liver injuries, and has a definite curative effect on hepatic ischemia-reperfusion injuries and chronic liver injuries, and the effect is superior to that of positive medicine namely Gansu Granules, so that the penthorum chinense pursh macrocyclic polyphenol monomer can be used for replacing the Gansu Granules and has a good clinical application prospect.

Description

technical field [0001] The present invention relates to the use of C. chinensis monomer in the preparation of liver protection drugs, specifically, chopinenine dihydrochalcone-7-O-[3"-O-galloyl-4", 6"-hexahydroxybiphenyl Use of formyl]-β-D-glucoside in the preparation of liver protection drugs. Background technique [0002] Common liver injuries include ischemia-reperfusion liver injury and chemical liver injury. Among them, ischemia reperfusion injury (ischemia reperfusion injury, IRI) is one of the most common problems in surgical clinic. Ischemic injury occurs when the blood perfusion flow of tissues and organs is reduced due to various reasons, and after the blood perfusion is restored, the cell function metabolism and structural damage are aggravated, resulting in ischemia-reperfusion injury. Today, as the technology of liver transplantation is becoming more and more mature, after the transplanted liver undergoes ischemic injury, with the opening of the blood, it will...
