This study was designed to investigate the possible utilization of Castanopsis cuspidata as a source of antiseptic agents. The leaves of C. cuspidata, extracted by 80% ethanol, were sequentially fractionated with n-hexane, dichloromethane, ethylacetate, and n-butanol. In order to effectively screen for a natural preservative agent, we first investigated the antioxidant activities such as DPPH radical scavenging capacity, superoxide radical scavenging capacity, and xanthine oxidase inhibitory activity of the C. cuspidata ethanol extracts and fraction. Using a screening system, we found that the ethylacetate fraction had the strongest antioxidant activity, which followed a dose-dependent manner. The antimicrobial activities were shown in the ethylacetate fraction of C. cuspidata. Among the five fractions, the ethylacetate fraction showed the highest antimicrobial activities against microorganisms tested, which were Bacillus sublitis, Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, Salmonella enteritidis and Salmonella typhimurium. In addition, leaf extracts of C. cuspidata could be suitable for the development of food preservatives.
