ABSTRACT
Antioxidants activities from plant sources have attracted a wide range of interest across the world in recent times. This is due to growing concern for safe and alternative sources of antioxidants. The free radical scavenging activity using peroxidase assay, Ferric Reducing Ability of Plasma (FRAP), Lipid Peroxidation assay (LPO), ABTS (2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium) and the estimation of total phenolics content using the Folin-Ciocalteu reagent and total flavonoid content using aluminium chloride method were carried out on the methanol extracts of different plant parts of Argemone mexicana. Argemone mexicana extract effectively scavenged free radicals at all different concentrations and showed its potent antioxidant activity. Further, these effects were in a dose dependent manner. The fruits exhibited remarkable ability to scavenge the species LPO (39.193±1.257 MDA/g DW), ABTS (68.23±3.02 mM L-1 g-1) while flowers showed maximum peroxidase activity (0.513 mM min-1 g-1 DW) and FRAP (287±9.64). The total phenolic content was in the range 4.0-23.5 mg GAE/g DW while the total flavanoid content was in range 3.5-34.5 mg QE/g DW. The results suggest that methanol extract of the plant is very rich in antioxidant compounds and worthy of further investigations.
