Nanotechnology has attracted a lot of attention from every generation: either its new or old generation. Biosynthesized nanoparticles have been used mainly because of their medicinal properties. An important medicinal property of these nanoparticles is their antibacterial behavior against Gram positive and Gram negative bacteria. ZnO nanoparticles of Arisaema tortuosum (Wallich) Schott, and Rhus parviflora Roxb., leaves extract were synthesized by biochemical (precipitation) method and characterized by X-ray diffraction and UV-Visible spectroscopic analysis. At concentration 200 µg/ml, their antibacterial activity was evaluated against both Gram positive (Staphylococcus aureus) and Gram negative (Pseudomonas aeruginosa) bacteria and the results showed the antibacterial activity order as: ZnO nanoparticles (R. parviflora) > ZnO nanoparticles (A. tortuosum).
