Antiulcer effect of flavonoids. Role of endogenous PAF

Quercetin, rutin and kaempferol, administered intraperitoneally (25–100 mg/kg) inhibited dose‐dependently gastric damage produced by acidified ethanol in rats. Flavone was inactive while naringin was active at higher dose (200 mg/kg). The flavonols tested inhibited dose‐dependently the mucosal content of platelet‐activating factor (PAF) suggesting that the protective effects of these substances may be mediated by endogenous PAF.
