摘要: A detailed study has been performed on the antioxidant activity of acetone and methanol extracts stem bark plant, Shorea roxburghii. The total phenolic content were determined by DPPH, radical scavenging, ferric ion reducing power, hydroxyl radical, ABTS. scavenging hydrogen peroxide activities. Reducing efficiency S. roxburghii towards silver nanoparticles evaluated using surface plasmon resonance transmission electron microscope. Spherical shapes particles with 4–50 nm have reported. Formation ascertains role water soluble compounds present in Both was found to be a potent antioxidant. This work provides scientific support for high this plant thus it may find potential applications treatment diseases caused free radical. extract could used as green agent synthesis Ag nanoparticles.
