Madhu Kushwaha* and Sailesh Narayan

Abstract

Solanum virginianum (Family: Solanaceae) commonly known as the Indian night shade or Yellow berried night shade (English) and kantakari (Sanskrit). Solanum virginianum has as expectorant and antipyretic activities. Antioxidants that have traditionally been used to inhibit oxidation in foods also quench dreaded free radicals and stop oxidation chains in-vivo. Quantitative DPPH radical scavenging assay Radical scavenging DPPH assay were conducted using the standard protocols. These findings show that the Solanum virginianum extract possesses antioxidant activity. DPPH assay revealed that leaf extract had the highest antioxidant activity comparable with Vitamin C (leaf IC50 =58.3±0.33μg/mL; Vitamin C=21.7±0.36μg/mL).

Keywords: Solanum virginianum, phytochemical screening, antioxidant activity, quantitative DPPH, TPC, TFC.
