Phytochemical Study and Antioxidant Activities of the Coastal Asteraceae Achillea Maritima

Abstract

Abstract – This work was focused on the phytochemical study and antioxidant activities of hexane, dichloromethane, ethyl acetate, butanol and aqueous extracts, from the aerial parts of Achillea maritima. The antioxidant activity of Achillea maritima extracts was evaluated using the two methods DPPH and FIC. The DPPH activity revealed that ethyl acetate and butanol extracts have an important antioxidant activity at 0.12 and 0.06 mg/mL for the aerial parts of the plant with a percentage of inhibition ranging from 88.29 to 89.72 %, respectively. The results obtained showed that the ethyl acetate extract exhibited a significantly higher ferrous ion chelation activity (83.1%) than the other extracts compared to the EDTA positive control (100%). Dichloromethane and it aqueous extract showed an average capacity for chelation of Fe2+ (48.88 % and 45.81 %, respectively). However, the hexane and butanol extracts have a low chelating power (9.5% and 11.3%, respectively).
