초록

This study was conducted in order to investigate the antioxidant and antimicrobial activity of Solanum nigrum L. fruit powder after undergoing different extraction solvent processes. The total phenolic content of Solanum nigrum L. fruit powder measured a 14.66 GAE mg/g after undergoing ethanol extraction, and the total flavonoid content measured at 201.23 mg CE/g when undergoing ethanol extraction. The ABTS radical scavenging activity was 160.38~209.53 TEAC umol/g, and the DPPH radical scavenging activity was 53.99~90.76 TEAC umol/g, which indicated a higher level of antioxidant power in the ethanol extract as opposed to in the water extract. The FRAP (ferric reducing antioxidant power) of Solanum nigrum L. fruit powder was 115.58~194.58 TEAC umol/g, and B. subtilis KCTC 2189 showed greater antimicrobial activity in the ethanol extract (concentration 200 ug/uL) as opposed to the water extract. Solanum nigrum L. fruit powder revealed differences in antioxidant and antimicrobial activity between the different extraction solvents. In particular, ethanol extract had higher antioxidant and antibacterial activity, meaning it is more favorable for usage as a functional food material.
