Abstract

The present study was focused on the antioxidant activity of sequentially extracted different solvent extracts of C. dactylon growing in coastal area of Bangladesh. Powdered plant materials were continuously extracted with different solvents (petroleum ether, chloroform, methanol and water) and tested for antioxidant activity using reducing power assay, total antioxidant activity and reduction of ferric ions and also the extracts were tested to determine the available phytochemicals. The petroleum ether (PEE) extract showed appreciable antioxidant activity for reduction of ferric ions and methanol extract (ME) showed more effective total antioxidant activity. PEE, chloroform extract (CE) and aqueous extract (AE) also showed the moderate antioxidant activity.
