Embodiment 1

[0040] The preparation of embodiment 1 macrocyclic polyphenol compound

[0041] (1) Extraction and preliminary separation of herbal medicines

[0042] Grind 5kg of root vegetables, extract three times with 70% ethanol under hot reflux, each extraction time is 1 hour, add 15L of liquid each time, combine the extracts, concentrate under reduced pressure (55°C) until there is no alcohol smell to obtain the crude extract extract (relatively The density is 1.12~1.18), and its weight is 625g, and the yield is 12.5%. Then water (650ml) was suspended and passed through a macroporous resin column (D-101), followed by elution with water, 10% ethanol, 20% ethanol, 30% ethanol, 50% ethanol, 70% ethanol and 95% ethanol. The liquid is 10 to 12 times the volume of the column, and the eluents of water, 10% ethanol, 20% ethanol, 30% ethanol, 50% ethanol, 70% ethanol and 95% ethanol are respectively obtained, and concentrated under reduced pressure (55°C) to The extracts (relative density: 1....

Abstract

The invention provides a new use of a macrocyclic polyphenol compound separated from a penthorum chinense pursh extract in pharmacy. The macrocyclic polyphenol compound comprises a compound 1, a compound 2, a compound 3 and a compound 4, wherein the structural formulas of the compounds are as shown in the specification; the compounds have the following pharmacological activities that (1) the alpha-amylase activity is significantly inhibited, and the compounds have certain hypoglycemic effects, and (2) TGF (transforming growth factor)-beta1-induced hepatic stellate cell proliferation is significantly inhibited, and the compounds have anti-liver-fibrosis effects by pharmacology and efficacy experiments. The invention provides a novel medicament for preventing and treating diabetes mellitus, and an anti-liver fibrosis medicament. The medicament is abundant in raw material source, small in side effect, and beneficial to environmental protection, and has a relatively great clinical application value.

Description

technical field [0001] The present invention relates to traditional Chinese medicines, in particular to the use of traditional Chinese medicines, in particular to macrocyclic polyphenol compounds and their preparation and use in the preparation of medicines for preventing and treating diabetes and liver fibrosis. Background technique [0002] Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia caused by various etiologies. With the change of human life style, the incidence of diabetes is gradually increasing, and it is expected to reach 300 million people by 2025, seriously endangering human health and social development. Abnormal glucose metabolism is the main pathological factor of diabetes, and the related enzymes involved in glucose metabolism have an important impact on glucose metabolism. Diabetes research progress, Chinese Journal of Traditional Chinese Medicine, 2012, 37(23): 3519-3525). Hypoglycemic drugs usually include traditional Ch...
