Abstract:Hawthorn is a plant species belonging to the genus Crataegus of the Rosaceae family.It contains various vitamins and flavonoids and has several health benefits. Hawthorn flavonoids exert significant health-promoting effects on the cardiovascular system，such as lowering blood fat，increasing coronary flow，strengthening the heart， lowering blood pressure， and protecting vascular endothelial cells， in addition to having an antiarrhythmic effect.Additionally，they protect the liver and brain，and exhibit anti-tumor and anti-oxygenation activities.The methods used for hawthorn flavonoid extraction include hot water extraction，organic solvent extraction， ultrasonic-assisted extraction， microwave-assisted extraction， enzymatic hydrolysis， supercritical extraction，ultra-high pressure extraction，and macroporous resin adsorption.In this paper，the health-promoting effects and extraction techniques of hawthorn flavonoids were reviewed to provide reference for their application and production，and to present the direction for future research.
