Title: Antioxidant and Antimicrobial Activity of Aqueous and Methanolic Extracts of Mentha rotundifolia L. from Algeria
Abstract: Plants are an essential and integral part of complementary and alternative medicine due to their ability to generate secondary metabolites that are used to restore health and treat many diseases. The aim of the present study was to determine the antioxidant and antimicrobial activities of methanolic and aqueous extract of stems and leaves of Mentha rotundifolia L. from Algeria. The amounts of total phenolics solvent extracts (methanol and water extract) for the two parts of plant were determined spectrometrically. From the analyses, leaves aqueous extract had the highest total phenolic content (20.75±0.643 mg GAE/g). The highest total flavonoids content was measured in methanolic leaves extract 1.97±0.035 mg CAE/g). However the methanolic leaves extract had the highest DPPH scavenging ability with the lowest IC50 value (0.7 ± 0.028 mg/ml), the same tendency was observed with ferric reducing power. Concerning β-carotene bleaching assays results showed that the stems aqueous extract exhibited the highest antioxidant ability with an IC50 near than standards (0.52 ± 0.024 mg/ml). The antimicrobial activity was studied; all extracts were tested against five bacteria and three fungal species.
