Preparation method and application of folium cortex eucommiae extract for preventing and treating hypertension kidney injury

Abstract

The invention discloses a preparation method and application of folium cortex eucommiae extract for preventing and treating hypertension kidney injury. The preparation method comprises the following steps of taking a certain amount of folium cortex eucommiae, extracting the folium cortex eucommiae with water of which the mass is 15 times that of the folium cortex eucommiae, performing refluxing for 2 hours at 100 DEG C, performing filtering to obtain filtrate for later use, adding water of which the mass is 15 times that of the folium cortex eucommiae, performing secondary boiling reflux, performing filtering, collecting the filtrate, mixing the two filtrates, performing concentrating and spray-drying, thereby obtaining folium cortex eucommiae extract. The folium cortex eucommiae extract disclosed by the invention is simple in preparation method, natural and energy-saving, can prevent and treat renal injury of spontaneously hypertensive rats, and can be used for preparing medicines orhealth-care foods for preventing and treating the hypertensive renal injury.

Description

technical field [0001] The invention relates to the field of health food, in particular to a preparation method and application of Eucommia leaf extract for preventing and treating hypertensive kidney damage. Background technique [0002] The prevalence of hypertension among adults in my country is about 18.8%, and it is increasing year by year. Kidney damage is one of the major complications of hypertension. At present, most antihypertensive drugs mainly evaluate the antihypertensive effect, and less attention is paid to the renal damage caused by hypertension. The kidney is one of the target organs damaged by hypertension. Generally speaking, most hypertensive patients who have lasted for more than 5 years have varying degrees of kidney damage. At present, Western medicine mainly uses angiotensin-converting enzyme inhibitors and calcium ion antagonists to treat hypertensive renal damage. Their effects are mainly reflected in the effective reduction of blood pressure and ...

AI Technical Summary

Problems solved by technology

At present, Western medicine mainly uses angiotensin-converting enzyme inhibitors and calcium ion antagonists to treat hypertensive renal damage. Their effects are mainly reflected in the effective reduction of blood pressure and improvement of renal function, but the improvement of symptoms outside the kidney is not obvious.
