Rambutan fruits are consumed by people for additional food and medical use. Pericarp of
rambutan has been known to have some active compounds such as flavonoid. Many flavonoids
from plants are known to have anti radical activity effect or antioxidant. It is very interest to
determine of antioxidant activity from ethanol extract of rambutan pericarp (Nephelium lappaceum
L.). Antioxidant activity was carried out spectrophotometry by using DPPH (2,2-diphenyl-1-
picrylhydrazyl) as a reagent. The extract and vitamin E (-tocoferol) concentration was made 2, 3,
4, 5, and 6 g/ml. The increasing concentration of extract and vitamin E has caused the scavenging
of free radical DPPH. The amount of free radical scavenging DPPH was calculated based on its
absorbance, measured at 521 nm. The result showed that anti radical activity of ethanolic extract
of rambutan pericarp (EC50 = 1,62 g/ml) is higher than that of vitamin E (EC50 = 2,91 g/ml).
