The present study involves assay of the in vitro antioxidant activity of methanolic extracts of leaf, stem, fruit and root of Solanum erianthum. The in vitro antioxidant activity was evaluated by using free radical scavenging studies: DPPH radical scavenging, hydroxyl radical scavenging, hydrogen peroxide, reducing power, phosphomolybdate, total phenol and total flavonoid assay. The methanolic extracts exhibited a dose-dependent scavenging activity of DPPH, hydroxyl radical and hydrogen peroxide. All the extracts showed significantly higher inhibition percentage and positively correlated with total phenolic content. In addition, the total antioxidant assay established the antioxidant property of the methanolic extracts. Fruit and leaf extracts proved to be effective for the said parameters.
