[Pharmacological action]: Pharmacological action of hawthorn leaf flavonoids for prevention and treatment of cardiovascular diseases: Hawthorn leaves contain various flavonoids such as rutin, hyperoside, quercetin and vitexin. Pharmacological and clinical experiments show that hawthorn leaves Flavonoids have antihypertensive, hypolipidemic, increased coronary flow, improved myocardial blood supply and oxygen supply to the cardiovascular system, and have good curative effects on cardiovascular diseases such as hypertension, hyperlipemia, coronary heart disease and angina pectoris.

(1) Cardiotonic effect: Hawthorn has the effect of increasing muscle contractility, increasing cardiac output, and slowing heart rhythm.

(2) Effects on coronary blood flow and myocardial oxygen consumption: Hawthorn extract and its total flavonoids have the effects of increasing coronary blood flow and reducing myocardial oxygen consumption and myocardial oxygen utilization.

(3) Effect on myocardial vascular blood flow: Hawthorn has a certain effect on myocardial vascular blood flow, and the effect of hawthorn on myocardial vascular blood flow may be related to dilating coronary vascular bed and improving coronary circulation.

(4) Protective effect on experimental myocardial ischemia: Hawthorn has protective effect on acute myocardial ischemia caused by isoproterenol sulfate in guinea pigs. Hawthorn extract has the effect of preventing or alleviating myocardial ischemia or necrosis of isoproterenol.

(5) Antihypertensive effect: Hawthorn ethanol extract has a longer-lasting antihypertensive effect.

(6) hypolipidemic effect: different extracts of hawthorn have a certain lipid-lowering effect on various high-fat models caused by different animals, which can antagonize the increase of serum cholesterol and triglyceride levels caused by high-fat diet.
