Abstract

In this study, three plants i.e. J. adhatoda, A. vulgaris and P. guajava native to Pashupati area and Jorpati of Nepal were screened to evaluate the phytochemical and antioxidant activities due to their high medicinal value. The dried leaves were extracted with three solvents: hexane, methanol and distill water. The extracts were subjected to various phytochemical tests. The test confirmed the presence of various phytochemicals. The antioxidant activity of the methanol extracts were evaluated by FRAP assay. The antioxidant activity of J. adhatoda was found to be 0.794mM Fe (II)/L, A. vulgaris to be 0.949 mM Fe (II)/L and P. guajava was found to be 2.035 mM Fe (II)/L. Fresh aqueous leaf extracts of A. vulgaris and J. adhatoda were used for synthesis of silver nanoparticles. The biosynthesized AgNPs were characterized by Transmission Electron Microscope (TEM).
