Abstract
Efficacy of antioxidative activity and nitrite scavenging ability of methanol extract from Ricinus communis. was investigated. Electron-donating ability of extract at RC50 was 114.02 ㎍/mL. After addition of 0.46 ㎎/mL extract, autoxidation of pyrogallol decreased to 32.99% by superoxide dismutase-like activity. In antioxidative activity of extract against linoleic acid during incubation times of 24, 48, 96 hours at 40℃, lipid peroxidation values significantly decreased by 85.50%, 87.77%, 90.95% with addition of 0.2 ㎎/mL, respectively. Total phenolic content was determined as gallic acid equivalents (GAE) and values revealed 83.98 ± 5.66 GAE ㎍/㎎ of extract. Nitrite scavenging ability showed the most remarkable effect at pH 1.2, decreasing to 47.24% by addition of 0.2 ㎎/mL. These results suggest that methanol extract from Ricinus communis. can be used as bioactive and functional material.
