ABSTRACT
The present study was undertaken to investigate antioxidant activity of ethanol extract (EE) and aqueous extract (AQE) of whole plant of Barleria prionitis Linn. Family-Acanthaceae. Radical-scavenging potential was evaluated using the DPPH radical, ABTS scavenging activity, Hydroxyl radical scavenging activity, reducing power assay and Nitrous oxide scavenging activity of Barleria prionitis Linn. extracts. Ethanol extract was the most effective antioxidant among the aqueous extract of Barleria prionitis Linn.. The order of the antioxidant potency of the whole plant extract is ethanol > aqueous. Phenolic content of the extracts was determined using Folin-Ciocalteau reagent. The results suggest a good correlation between antioxidant activity and phenolic content. Further studies are in process to isolate the active principles responsible for the activity.
