... flavonoids have been shown to inhibit carcinogen-induced tumors in rodents.In humans, the total average intake of quercetin and kaempferol is estimated at 20 mg/day andconsumption of quercetin from onions and apples was inversely correlated with lung cancerrisk. In this study, we report that quercetin...

Q3GA was found to be effective in the inhibition of lipid hydroperoxide-induced oxidative stress in the nerve cell model PC-12. Our in vivo study using high cholesterol-fed rabbits...
