Abstract


Antioxidant is a compound useful to prevent oxidative damage generated by free radical in human body, thus protecting body from many diseases. The aim of this research is to investigate antioxidant activity of some Indonesian medicinal plants. A total of 37 methanolic extracts of Indonesian plants have been screened for their antioxidant activity by in vitro method using the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH). Vitamin C was used as positive control. Of the samples investigated, 29 exhibited radical scavenging properties more than 50% at 1000 ppm. Five extracts exhibited high activities i.e. bark extracts of Sapium baccatum and Leucosyke capitellata, leaves extracts of Ardisia crispa, Glochidion cauliflorum, and Glochidion superbum.
