Abstract: Antioxidant activity studied by using the DPPH radical trapping test.For this purpose, the phenols and flavonoids compounds were dosed.Quantitation of the phenolic and flavonoid compounds of the aqueous extract to the solvent (diethyl ether and ethyl acetate) was determined by spectrometry.Finally, the DPPH trapping activity of the extracts increased in the order of: diethyl ether fraction <ethyl acetate fraction <ascorbic acid.The inhibition of mild steel in the 1M hydrochloric acid solution is also studied.The aqueous extract of leaves of Pancratium Foetidum Pom, was carried out by potentiodynamic polarization, electrochemical impedance spectroscopy and weight loss studies.The results obtained show that the inhibition efficiency increases with the increase in inhibitor concentration and the variation in the inhibitory efficiency depends mainly on the type and nature of the substituents presents in the mixture (aqueous extract) to reach 98 % To 1 g / L.
