Fenilpropanoidok - Szerves Kémiai Tanszék

FlavonoidokbiológiaihatásaiConsiderable quantities of flavonoids are consumed daily in ourvegetable diet, so adverse biological effects on man are notparticularly intense. Indeed, there is growing belief that someflavonoids are particularly beneficial, acting as antioxidants andgiving protection against cardiovascular disease, certain forms ofcancer, and, it is claimed, age-related degeneration of cellcomponents. Their polyphenolic nature enables them to scavengeinjurious radicals such as superoxide and hydroxyl radicals.The flavonol glycoside rutin from buckwheat (Fagopyrum esculentum; Polygonaceae)and rue (Ruta graveolens; Rutaceae), and the flavanone glycoside hesperidin fromCitrus peels have been included in dietary supplements as vitamin P and claimed to beof benefit in treating conditions characterized by capillary bleeding; their therapeuticefficacy is far from conclusive. Useful anti-inflammatory properties have beendemonstrated, however.
