The total polyphenol contents and antioxidative activities of water and ethanol extracts from Synurus excelsus and Synurus palmatopinnatifidus var. palmatopinnatifidus were determined. Total polyphenol contents of ESE and ESP were 195.7 and 216.2 mg/g, and were higher than WSE (74.7 mg/g) and WSP (77.4 mg/g). The total flavonoid contents were also higher in ESE (176.6 mg/g) and ESP (148.8 mg/g) than WSE and WSP. DPPH radical scavenging activities of ESE and ESP (73.1 and 73.4%) were higher than WSE and WSP as like total polyphenol and flavonoid contents. Although the DPPH radical scavenging activities of the extracts were proportional to total polyphenol contents, there are no differences between water extracts and ethanol extracts of Synurus excelsus and Synurus palmatopinnatifidus on ABTS radical scavenging activities. Moreover, all the solvent extracts (ESE, ESP, WSE and WSP) had no SOD-like activity. These results suggest that consideration for adoption of method is necessary to evaluate antioxidative activity of extracts from plants including vegetables.
