Preliminary screening of phytochemicals is a valuable step, in the detection of the bioactive principles present in medicinal plants and subsequently may lead to drug discovery and development. In the present study, chief phytoconstituents of the four selected medicinal plants (Hemigraphis alternate, Phyllanthus niruri, Tinospora cordifolia and Vitex negundo)of different families were identified in order to relate their presence with bioactivities of the plants. Screening of the plants was performed using standard methods and resulted in the detection of the presence of tannins, flavonoids, phenolics, steroids, cardiac glycosides, coumarins, terpenes and alkaloids. Flavanoids were found in four of the selected plants and alkaloids were found in three of them except Vitex negundo. The biosynthesis of silver nanoparticles from 1 mM AgNO3 solution using aqueous extracts of four plants were done and the surface plasma resonance was measured using UV-VIS spectrophotometry. These results validate the exploitation of the studied medicinal plants, for further isolation of active principles and their application in medical and Cosmetics industries.
