Flavonoids and Vitamin C
A study assessed the antioxidant potencies of several dietary flavonoids compared with vitamin C. Pretreatment with all flavonoids and vitamin C produced dose-dependent reductions in oxidative DNA damage. When ranked in order of potency, luteolin was two times more effective than vitamin C by the Trolox test and more effective than seven other flavonoids in…

When compared to other flavonoids, only luteolin and quercetin inhibited platelet-activating factor and suppressed a type of inflammatory response induced by allergens by inhibiting lipoxygenase. Luteolin inhibited the excess production of TNF-alpha, which directly causes inflammation and apoptosis (cell death). The scientists who conducted the study concluded that luteolin could be used to develop a…
