Abstract
In this study, Seseli praecox of Algerian flora was investigated regarding their polyphenolic and
flavonoids contents using the Folin–Ciocalteu and aluminum chloride colorimetric methods,
respectively. TPC of crude aqueous ethanolic extract was 44mg± 0.09GAE/gDw, while, TFC have values
of 1.53mg±0.01 QuercetinE/gDw and 6.93mg±0.01 RutinE/gDw for ethanolic extract, which mean that
this plant is relatively poor source of polyphenols and flavonoids . In the other side, the polyphenolic
extract of this plant was evaluated for its reducing power. The capacity of the extract to reduce the ferricferricyanide
complex to the ferrous-ferricyanide complex mention that Seseli praecox showed a very high
iron reducing power activity with Ec50=0.25mg/ml.
