Illicium verum (badiane or star anise), Crataegus oxyacantha ssp monogyna (hawthorn) and Allium cepa (onion), have traditionnally been used as medicinal plants in Algeria. This study showed that the outer layer of onion is rich in flavonols with contents of 103 +/- 7.90 mu g/g DW (red variety) and 17.3 +/- 0.69 mu g/g DW (white variety). We also determined flavonols contents of 14.3 +/- 0.21 mu g/g 1.65 +/- 0.61 mu g/g for Crataegus oxyacantha ssp monogyna leaves and berries and 2.37 +/- 0.10 mu g/g for Illicium verum. Quantitative analysis of anthocyanins showed highest content in Crataegus oxyacantha ssp monogyna berries (5.11 +/- 0.266 mg/g), while, inner and outer layers of white onion had the lowest contents with 0.045 +/- 0.003 mg/g and 0.077 +/- 0.001 mg/g respectively. Flavonols extracts presented high antioxidant activity as compared with anthocyanins and standards antioxidants (ascorbic acid and quercetin). Allium cepa and Crataegus oxyacantha ssp monogyna exhibited the most effective antimicrobial activity.
