Benefits of Pueraria extract Kudzu Root Powder

Pharmacological action

1.Effect on smooth muscle

(1) Effect on smooth muscle

The extract of Pueraria contains the components of contraction and relaxation of smooth muscle, the extract of Pueraria and the total flavones can inhibit the contraction of isolated rat ileum induced by acetylcholine (Ach) and PGF2 α, and have obvious relaxation effect on normal rats, daidzin and Daidzein are the main components of smooth muscle relaxation, and Daidzin is the main component of Pueraria extract for Spasmolysis, while the contractile component may be non-flavonoid.

(2) Effects on blood pressure and heart rate

Pueraria extract has a certain antihypertensive effect on normal and hypertensive animals, intravenous Administration of Pueraria extract, total flavone, Pueraria Montana extract and its fat-soluble part PA and water-soluble part PM can reduce blood pressure of normal anesthetized dogs, oral Pueraria extract water decoction or wine extract or total flavonoids and Pueraria extract on dogs with hypertension also have a certain hypotensive effect.

PM2 causes an increase in blood pressure in normal dogs, suggesting that Pueraria’s extract contains not only antihypertensive substances, but also substances 6,7 that raise blood pressure. 2. Pueraria extract flavone and Pueraria extract made the heart rate of normal and myocardial ischemia dogs significantly decreased 6,7.

(3) Beta blocker

Pueraria extract has a broad and significant blocking effect on β receptor, and its effect on Β1 receptor is stronger than that on Β2 receptor, while Pueraria extract has a stronger blocking effect on Β1 receptor.The maximal binding capacity of β receptor in rat myocardial membrane preparation was significantly reduced, and the activation of Adenylate cyclase (AC) was completely inhibited by Epinephrine, which suggested that Pueraria extract was a receptor antagonist.

(4) Impact on blood flow

Pueraria Montana extract can obviously improve the microcirculation of normal golden hamster brain, and can obviously improve the disturbance of microcirculation caused by local (-)-noradrenaline.

Total flavone of Pueraria Montana extract has a more obvious effect on cerebral vasodilation than coronary vasodilation, and can mildly improve cerebral circulation and peripheral circulation.

Pueraria Montana extract, wine extract, total flavonoids, Puerarin and Daidzein all improved acute myocardial ischemia in rats.

(5) Effects on cardiac function and myocardial metabolism

Total flavonoids from Pueraria Montana extract and Pueraria Montana extract can reduce myocardial oxygen consumption and increase coronary artery oxygen supply, clinical use of Angina has a certain effect.

Total flavone of Pueraria Montana extract can improve the metabolism of normal and ISCHEMIC myocardium.

(6) Effects on blood catecholamine

Pueraria Montana extract can relieve headache in patients with hypertension and reduce the level of plasma catecholamine in patients with Angina Pectoris, which is related to the reduction of lactic acid production in myocardial ischemia.

(7) Effects on Arrhythmia

Pueraria Montana extract, Daidzin and Pueraria Montana extract could significantly prevent aconitine and Barium chloride (Bacl2)-induced Arrhythmia.

3. Effects on memory
