This study was performed to investigate the biological activities of roasted (RE) and non-roasted (NRE) hot water extract samples from Euonymus alatus leaf by measuring DPPH radical scavenging, total polyphenol content, hydroxyl radical scavenging, superoxide dismutase (SOD)-like activity, anti-inflammatory activity, and inhibitory effects on α-amylase and α-glucosidase in vitro. The IC∧50 values for DPPH free radical scavenging activity of the NRE and RE hot water extracts were 19.1 ㎍/mL and 21.9 ㎍/mL, respectively, and their total polyphenol contents were estimated as 9.6 mg/g for NRE and 10.6 mg/g for RE.
