The Antioxidant Activity of Maesil (Prunus mume)

摘要

Antioxidant activity of Maesil (Prunus mume) was evaluated based on peroxide value (POV), thiobarbituric acid reactive substances (TBARS value), and electron-donating ability using l,l-diphenyl~2-pycryl hydrazil (DPPH) method. POVs for soybean oil with 0.02% antipxidants were 276.93, 223.32, 217.38, 238.40, and 226.55 meq/kg in control, ascorbic acid, dibutyl hydrwxytoluene (BHT), extract of dehydrated Maesil flesh (EDMF), and extract of dehydrated Maesil juice (EDMJ), respectively. Antioxidant activities for TBA values were 29.94, 45.35, 13.81, and 25.00% in ascorbic acid, BHT, EDMF, and EDMJ, respectively. Electron-donating abilities by DPPH were 96.69, 77.82, 34.84, and 43.50% in ascorbic acid, BHT, EDMF, and EDMJ, respectively. EDAs by DPPH with0.02% EDMF and EDMJ were 53.21 and 59.19%, respectively.
