| Résumé : |
Medicinal plants are considered an important source of bioactive compounds capable of neutralizing free radicals and preventing cellular damage. The present study aims to extract the bioactive molecules from the plant Mentha spicata L. by decoction and infusion, to determine their phenolic and flavonoid contents and demonstrate their antioxidant activities. The decocted extract shows a better yield (18.8%) and very high contents of polyphenols (0.135±0.120mg EAG/g of extract) and flavonoids (5.32±2.07 mg EQ/g of extract). The infused extract shows a more potent scavenger effect on the DPPH radical (IC50=0.071 ± 0.011 mg/ml) than the decocted extract (IC50=0.075 ±0.019 mg/ml). Inthe ferrous iron chelation test, the infused extract always showed a hiher chelating effect (IC50=0.040±0.002 mg/ml) than that of the decocted extract. This study confirms and justifies the medicinal and traditional use of the plant Mentha spicata L. |
