Medicinal plants have attracted a great deal of scientific interest due to their potential as a source of natural biologically active compounds especially the antioxidant properties of medicinal plants that have created its wider applications including pharmaceuticals, alternate medicine, and natural therapies. The present study was to evaluate the qualitative estimation of phytochemicals and antioxidant properties from leaves, stem, and root of Neolamarckia cadamba and Cymbopogon citratus. In our study, we found the presence of steroids, flavonoids, alkaloids, tannins, saponins, and cardiac glycosides and antioxidant features in both plants and found suitable for the therapy of oxidative damages. In the present study, free radical scavenging percentage activity was found maximum in aqueous stem extract of Neolamarckia cadamba (81% with 1.5 ml extract) and least in aqueous stem and leaf extract of Cymbopogon citrates (1.67% and 1.67% with 0.5 ml respectively). From the present work, it becomes possible to conclude that these plants could be a promising source of bioactive compounds and warrant further study.
