Phytochemical analysis, free radical scavenging capacity and antimicrobial properties of Impatiens bicolor plant
The air dried powdered plant materials were extracted with different organic solvents, screened for phytochemicals and analyzed for their biological activities. The antioxidant potential was evaluated by scavenging of DPPH radical, TPC and TFC, while antimicrobial activity by disc diffusion assay against a set of bacterial and fungal strains. Ethylacetate extracts showed higher free radical scavenging capacity and phytochemical analysis revealed the presence of alkaloids, tannins, steroids, saponins and flavonoids. In biological assay, the extracts showed the antimicrobial activity comparable with standard antibiotics.
