Antioxidative Activities of 60 Plant Extracts

초록

The methanol extracts from 60 plant extracts were prepared and evaluated for their antioxidative activ-ity. Arctium lappa, Diospyros kaki, Eugenia caryophyllata, Melia azedarach and Forsythia suspensa showed theinhibitory activity against lipid peroxidation. Caesalpinia sappan, Crataegus pinnatifida, Eugenia caryophyllata,Gleditsia japonica, Osmunda japonica, Rhus javanica and Sanguisorba officinalis showed the highest inhibitoryactivity against DPPH radical formation. In particular, Eugenia caryophyllata demonstrated strong inhibitoryactivity on the lipid peroxidation and free radicals. The results suggested that selected plant extracts have a potentialas natural antioxidant. Keywords□ antioxidative activity, inhibition, lipid peroxidation, free radical scavenging, plant extract
