Abstract:

In the present study, we determined the antioxidant activity of the entire plant of Phyllanthus reticulatus by performing different in vitro antioxidant assays, including 2,2-Diphenyl-1-Picrylhydrazyl (DPPH) radical scavenging, β-carotene bleaching, superoxide anion radical scavenging, reducing power and metal chelating assay at different concentrations (100, 200 and 400 μg/ml). The entire plant powder of P. reticulatus shows good antioxidant activity of about 90.0% when compared with standard Butylated Hydroxy Toluene (BHT) (85%) at a concentration of 400 μg/ml. Results obtained reveal that methanolic extracts of entire plant of P. reticulatus possess higher antioxidant activity when compared with ethanolic extracts. Thus, this study suggests that P. reticulatus plant can be used as a potent source of natural antioxidants.
