|
Efficacy of antioxidative activity and nitrite scavenging ability of methanol extract from Acanthopanax sessiliflorus was investigated. Electron-donating ability of extract at was 29.93 . After addition of 0.96 mg/mL extract, autooxidation of pyrogallol decreased to 22.85% by superoxide dismutase-like activity. In antioxidative activity of extract against linoleic acid during incubation times of 24, 48, 96 hours at , lipid peroxidation values significantly decreased by 48.89%, 45.0%, 46.34% with addition of 0.2 mg/mL, respectively. Total phenolic content was determined as gallic acid equivalents (GAE) and values revealed GAE of extract. Nitrite scavenging ability showed the most remarkable effect at pH 1.2, exhibited to 88.3% by addition of 0.2 mg/mL. These results suggest that methanol extract from A. sessiliflorus can be used as bioactive and functional material.
