Abstract

The invention discloses a composition for preventing and treating diabetic nephropathy. According to the invention, an optimal compound combination for treating diabetic nephropathy is screened from salvia miltiorrhiza bunge through a large number of experiments; wherein the molar ratio of five molecules is (salvianolic acid B: rosmarinic acid : lithospermic acid: salvianic acid A: tanshinone IIA=1: 0.07: 0.04: 0.07: 0.05) and the molar ratio of three molecules is (salvianolic acid B: rosmarinic acid : lithospermic acid =1: 1.16: 0.02) have relatively good activity in HBZY-1 and HK-2 high glucose and hydrogen peroxide damage models, kidney injury caused by diabetes mellitus can be remarkably improved, and fasting blood glucose, triglyceride, urea nitrogen, creatinine, insulin, microalbuminuria, glutamic oxalacetic transaminase and glutamic-pyruvic transaminase levels of db/db mice with spontaneous diabetes mellitus are regulated; and pathological changes of kidney tissues are improved; and a good technical effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a molecular composition in salvia miltiorrhiza that can prevent and treat diabetic nephropathy and its application. Background technique [0002] Salvia miltiorrhiza is the dry root and rhizome of Salvia miltiorrhiza Bge., which is a plant of the genus Salvia in the Lamiaceae family. It was first recorded in "Shen Nong's Materia Medica", and was listed as the top grade. It has the effects of promoting blood circulation and removing blood stasis, dredging menstruation and relieving pain, cooling blood and eliminating carbuncle, clearing heart and eliminating troubles. Irregular menstruation, amenorrhea, upset and insomnia, accumulation of lumps, sores, swelling and pain. The chemical components in Danshen mainly include fat-soluble tanshinones and water-soluble salvianolic acids. More than 30 kinds of phenolic acids have been isolated from Salvia miltiorrhiza, mainl...
