Abstract

The herb Phyllanthus reticulatus is commonly known as potato bush, which is widely used in the indigenous system of medicine for the treatment of diarrhoea, diabetes, obesity and burns. The methanolic extract of the plant was studied for its in vitro free radical scavenging activity in different methods viz DPPH radical scavenging assay, ABTS radical scavenging assay, Ophenanthroline assay, lipid peroxidation assay, nitric oxide scavenging assay, superoxide scavenging assay, total antioxidant and non-enzymatic haemoglobin glycosylation assay. The results were analyzed statistically by regression method. Its antioxidant activity was estimated by IC 50 value and the values were 14.31 μgm/ml (DPPH radical scavenging), 10.51 μgm/ml (ABTS radical scavenging), 22.91 μgm/ml (O-phenanthroline assay), 32.16 μgm/ml (lipid peroxidation), 90.51 μgm/ml (nitric oxide scavenging) and 4.18 μgm/ml (superoxide scavenging). In total antioxidant capacity assay, 1 mg of extract is equivalent to 41.31 μg of ascorbic acid. It showed 83.69% inhibition of haemoglobin glycosylation.
