ASSESSMENT OF THE ANTIOXIDANT AND ANTIBACTERIAL ACTIVITIES OF PETIVERIA ALLIACEA AND VISCUM ALBUM (MISTLETOE). -

. The antioxidant and antimicrobial activities of the methanolic extracts of Petiveriaalliacea (Garlic guinea weed) and Viscum album (Mistltoe) from cocoa (Theobroma cacao) were investigated. Both samples showed good levels of DPPH radical scavenging activity with IC50 of 0.116mg/ml and 0.120mg/ml for V. album and P. alliacea respectively. The extract of V. album inhibited Pseudomonas aeruginosa, Escherichia coli, Klebsiellasp., Salmonella sp.,Shigellasp.,Proteus sp., and Staphylococcussp. with zones of inhibitions ranging from 3 to 25mm at extracts concentrations of 62.5, 125, 250 and 500mg/ml. The zones of inhibitions for P. alliacea ranged from 3 to 24mm for the same extract concentrations. V. albumhave the highest inhibition against E. coli and least inhibition against Staphylococcus sp., while P. alliacea have the highest inhibition against Shigellasp. And the least inhibition against Staphylococcus sp. - See more at:.
