Abstract: Acanthus ilicifolius is a mangrove plant and it used coastal village peoples for traditional folk medicine method for varies disease. In general salt tolerance plants have a more antioxidant constitute. In the present study researchers have examine different type of anti oxidant capacity like that total phenolic, DPPH radical, nitraxcite radical, hydroxyl radical and ABC radical in two solvent extract of ethanol and aqueous for different concentration like 0.1, 0.2, 0.5, 1.0 and 2.0. In the result showed that maximum in 2.0 mg mL-1 of leaves extract of ethanol and minimum in aqueous extract in 0.1 concentration for all antioxidant assay. In this result showed that highly effect in antioxidant levels in two solvent extract and varies concentration so there would be a good antioxidant property.
