چکیده    Ten flavonoids were isolated for the first time from the aerial parts of sisymbrium irio l. grown in saudia arabia, using chromatographic methods, and identified as apigenin, apigenin- 7-galactoside, apigenin-7-o-β-d-glucoside, luteolin-7-o-glucoside, apigenin-7-di-glucoside 5, apigenin-7-o-(6˝acetyl) glucoside, apigenin-7-o-gluco(6˝-1˝́) rhamnoside, apigenin-7-o-gluco (6˝-1˝́)rhamnoside-5-methoxide, kampferol and kampferol-3-xyloside-7-galactoside. the median lethal dose of the extract was determined in mice and found to be greater than 5000 mg/kg body weight, suggesting that this plant is non-toxic. antioxidant activities were assessed for all extracts and fractions (total, ether, chloroform, ethyl acetate and butanol) and isolated compounds, and showed variable antioxidant activity, with apigenin-7-o-galactoside being the most potent.
