Abstract

Different solvent extracts of Anthurium plowmanii leaves were assayed for anti-oxidant and antibacterial activities. Methanol extract has the highest inhibition of DPPH (2,2-diphenyl-2- picrylhydrazyl-hydrate) and ABTS (2,2'-azinobis (3-ethyl benzothiazoline-6-sulfonic acid)) scavenging activities. Concentrations of methanol extract required for 50% inhibition of DPPH radical scavenging effect were recorded as 231.59 μg/mL. The IC50 of methanol and water extracts on ABTS were 57.23 μg/mL and 73.35 μg/mL, respectively. The lower IC50 values was denoted for a more potent antioxidant. Dichloromethane and n-hexane extracts showed faint anti-bacterial activities against bacteria Pseudomonas aeruginosa and Bacillus subtilis that were evaluated by broth dilution method. The results demonstrated great potential of the A. plowmanii leaves as a new source of new antioxidant agents.
