Item Antioxidant and Antitumorigenic efficacy of methanolic extracts of Gloriosa superba and Silver Nanoparticles of methanolic extracts of Gloriosa superba to DLA tumor cells(2013-03) Saradha Devi, K M; Annapoorani, SItem Antioxidative Activity of Methanolic Extract of Gloriosa Superba Seed, Tuber and Leaves(2013) Saradha Devi, K M; Annapurani, SMedicinal plants play a key role in the human health care. About eighty percent of the world populations rely on the use of traditional medicine, which is predominantly based on plant materials. The present study was carried out to evaluate the antioxidative activity of methanolic extract of Gloriosa superba seed, tuber and leaves (MEGSSTL). The percentage radical scavenging of MEGSSTL on DPPH and the IC50 (50% inhibitory concentration) value was found to be 38, 52 and 74 pg., hydrogen peroxide scavenging activity of MEGSSTL and the IC50 value was found to be 50, 63 and 68 pg., nitric oxide scavenging activity of MEGSSTL and the ICso value was found to be the 61,71 and 84 pg., hydroxyl radical scavenging ability of MEGSSTL to 50 percent was found to be 70,76 and 85 pg (ICso) ond superoxide radical production in vitro in a dose dependent manner with an IC50 of 58,70 and 75 pg. respectively. The dose dependent percentage scavenging activity of DPPH, hydrogen peroxide, nitric oxide, hydroxyl and superoxide radical by methanolic extracts indicated its antioxidative efficacy.Item Biochemical Profile of Calotropis procera(2010) Saradha Devi, K M; Annapurani, S
