1. The effect of puerarin on the liver system
Puerarin contains saponins, which have a protective effect on liver tissue immune damage. The C-29 hydroxyl group and C-5" oxygen-containing group can enhance the liver protection activity. Puerarin can protect liver damage through stomach absorption and induce activation of hepatitis It can effectively reverse chemically-induced liver fibrosis, protect against carbon tetrachloride-induced acute liver injury, and have various physiological activities.
2. The effect of puerarin on the cardiovascular system
The total flavonoids in pueraria can increase the blood flow of the brain and coronary arteries. Puerarin can obviously promote the cerebral circulation and peripheral circulation of animals and humans. Pueraria lobata total flavonoids have a mild promoting effect in improving the cerebrovascular tension, elasticity and pulsatility supply of patients with hypertension and coronary heart disease. Puerarin not only improves the normal brain microcirculation of the human body, but also has a significant improvement effect on microcirculation disorders, which is mainly manifested in the increase of local microvascular blood flow and movement. Puerarin can also improve the nail fold microcirculation of patients with sudden deafness, speed up the blood flow of the capillaries, clear the congestion of the vascular loops, and improve the hearing of the patients. Puerarin has a protective effect on hypoxic myocardium. Puerarin can significantly reduce the oxygen consumption of ischemic myocardium and protect the heart from ultrastructural damage caused by ischemia-report perfusion.
3.Puerarin is a single-component flavonoid glycoside extracted from the legume Pueraria lobata root. It has the functions of promoting blood circulation and removing blood stasis, improving microcirculation, dilating coronary arteries and cerebral vessels, and reducing myocardial oxygen consumption. Its preparation puerarin injection is clinically used It is used to treat cardiovascular and cerebrovascular diseases, retinal vascular diseases, fundus diseases and sudden deafness.
