This study examined the physiological activities as well as the total polyphenol and flavonoid content of water extract (WE), ethanol extract (EE) and hot water extract of Calystegia japonica leaves under high pressure (HWE). The xanthine oxidase inhibitory rate of EE was the highest with a value of 98.89% at a concentration of 1.0 mg/mL, whereas the rate of WE and HWE was over 90% at a concentration of 0.3 mg/mL. The superoxide dismutase (SOD)-like activity of HWE was the highest at 18.88%. The nitrite scavenging abilities were 64.59-66.46% at conditions of pH 1.2 and 1.0 mg/mL, and 52.78-55.89% at pH 3.0. The electron donating ability of EE was the highest with a value of 84.80% at a concentration of 0.1 mg/mL. All extracts showed the highest degree of electron donating at the concentration of 0.1 mg/ mL, and this effect decreased as the extract concentration increased. The EE had the highest content of total polyphenol compound (173.89 mg/g) and flavonoid compounds (40.68 mg/g).
