In the present investigation, phytochemical screening of different extracts of Wrightia tinctoria has been tested by using standard procedures. The findings showed the presence of alkaloids, flavonoids, phenols, steroids, terpenoids and glucosides. Among the four solvents tested (aqueous, ethanol, N-hexane and ethyl acetate) ethanol extract of leaf showed the best result. The free radical scavenging activity of both the extract was measured by using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. The aqueous and ethanol extracts of Wrightia tinctoria leaf shows slightly different antioxidant activity. The remarkable activity showed by the plant is due to the synergic effect of active compounds present in it.Characterization of phytochemicals was done by using UV-Visible spectrophotometry, FTIR analysis and Thin layer chromatography
