The Antioxidant and antihemolytic activities of hydroalcoholic 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 antihemolytic 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. La actividad antihemolítica y antioxidante de extractos hidroalcohólicos de flores, tallos y hojas de Ferula gummosa Boiss fueron investigados empleando diferentes ensayos in vitro. Los extractos de hojas mostraron una mejor actividad captadora de radicales libres. Además, mostraron una mejor actividad captadora de óxido nítrico y H2O2 y actividad quelatante de Fe2+ que las otras partes. Los extractos exhibieron una buena actividad antioxidante en el ensayo con ácido linoleico pero no comparable con la vitamina C (p< 0.001). Los extractos mostraron una débil actividad de poder reductor. Los extractos de tallos de F. gummosa mostraron una mejor actividad antihemolítica contra la hemolisis inducida con H2O2. Entre los extractos, las flores tienen los más altos contenidos de fenoles y flavonoides. Esta planta es muy prometedora para futuros experimentos bioquímicos
