Abstract
Electron donating abilities, nitrite scavenging effects and antimicrobial activities of various fractions obtained from ethanol extract of Smilax china were examined. Among the fractions investigated, the highest electron donating ability was determined with ethyl acetate fraction showing about 81.0% when reacted for 10 min. However, the lowest ability was found from chloroform fraction. Ethyl acetate and butanol fractions also showed very high nitrite scavenging activity at all concentrations tested. All the fractions revealed antimicrobial activity against Listeria monocytogenes and Staphylococcus aureus, Gram (+) bacteria, at both 2.5% and 5.0% concentrations. However, no antimicrobial activity was observed on Escherichia coli O157:H7 and Salmonella Typhimurium, Gram (-) bacteria, at 2.5%, but very low activity was detected by 5.0% concentration of ethanol extract, ethyl acetate and water fractions.
