Fa'aaogāga

Quercetin, e pei o le flavonoids sili ona taatele, o loʻo i ai ni gaioiga faʻapitoa ma e mafai ona tetee atu i le faʻamaʻiina, o loʻo faia se sao taua i le togafitiga o le kanesa ma faʻamaʻi cardiovascular. Quercetin e le gata e auai i le in vitro antioxidant activity ma e mafai ona faʻalavelaveina le faʻaleagaina o le DNA, ae puipuia foi aano mai le faʻaleagaina o le oxidative e ala i le faʻaitiitia o le faʻaogaina o le peroxide i vivo.
