Antioxidant activity of flower, stem and leaf extracts of Ferula gummosa Boiss

The Antioxidant and anti hemolytic activities of hydro alcoholic extracts of the flowers, stems and leaves of the Ferula gummosa Boiss were investigated employing different in vitro assay systems. Leaf extract showed better activity in DPPH radical scavenging. In addition it showed better activity in nitric oxide and H2O2 scavenging and Fe2+ chelating activity than the other parts. The extracts exhibited good antioxidant activity in linoleic acid system test but were not comparable with vitamin C (p< 0.001). The extracts showed weak reducing power activity. The F. gummosa stem extract showed better anti hemolytic activity against H2O2 induced hemolysis. Among the extracts, the flowers had higher phenolic and flavonoid contents. This plant is very promising for further biochemical experiments. (Author) 43 refs.
