Abstract Avicennia officinalis is a mangrove plant and is used by coastal village peoples in traditional folk medicine -for a variety of diseases. In general, salt tolerant plants have a more antioxidant profile. In our present study, we examined different types of antioxidant capacity like that of phenolics against DPPH nitroxide, hydroxyl and ABC radicals in two solvent extracts of ethanol and water at different concentrations of 0.1, 0.2, 0.5, 1.0 and 2.0 mg/ml. Our results showed maximum activity in 2.0 mg/ml of leaves extract of ethanol and minimum activity in aqueous extract of 0.1 mg/ml concentration for all antioxidant assays. The results showed highly effective antioxidant activities in two solvent extracts at a different concentrations, therefore, the extracts have good antioxidant properties.
