Abstract
This study was conducted to examine the physiological activities of Lespedeza cundata extracts. The extraction yield of 50% ethanol extract (17.60%) was higher than that of hot water extract (12.60%). The total phenolic and total flavonoid contents of the 50% ethanol extract were 242.26 mg/g and 160.73 mg/g, respectively. The DPPH radical scavenging activities of the hot water and 50% ethanol extracts were 92.07% and 96.38%, respectively. The superoxide radical scavenging activities of hot water and 50% ethanol extracts on 250~1,000 μg/mL were 54.89~85.68% and 44.50~94.46%, respectively. The tyrosinase inhibition activity of the 50% ethanol extract at 1,000 μg/mL (63.31%) was the highest. The nitrite scavenging activity of the 50% ethanol extract was higher than that of the hot water extract. The nitric oxide production of 50% ethanol extract (7.15~20.61 μM) improved with an increase in the treatment concentration. The hot water and 50% ethanol extracts at 1,000 μg/mL inhibited the proliferation of the cancer cell lines A549, HeLa, Hep3B, and Sarcoma180. There results suggest that the 50% ethanol Lespedeza cuneata extracts may be useful as a functional food material in the food industry.
