| Résumé : |
The objective of this study was to determine the phenolic content and evaluate the antioxidant activity of ethanolic Azolla extract. The quantitative estimation of polyphenols and flavonoids showed the presence of 25 ±0.28μg EAG/mg and 3.40 ±0.16 μg EC/mg of extract respectively. The antioxidant activity of this plant was assessed by various methods: the DPPH test shows that Azolla has a potency IC₅₀ = 0.0094±0.003 mg/ml also the H2O2 scavenging test gives IC₅₀ = 0. 43±0.082 mg/ml and the chelating activity on Fe²⁺ shows IC₅₀ = 0.064±0.0062 mg/ml and the reducing power of ferric iron whose IC50 is 28.22±0.38 %. In conclusion, it has been shown that the ethanolic extract of Azolla is rich in phenolic compounds. |
