Abstract
Antioxidant is oxidative reaction inhibitor damage induced by free radical. A phenolic compound and flavonoid act as antioxidant. Durian (Durio zibethinus L.) plant contains phenolic compound and flavonoid. The study was aimed to determine the antioxidant activity of ethanolic extract of young leaves of durian to DPPH radicals with IC50 parameters and screening phytochemistry of ethanolic extract of young leaves of durian. The young leaves of durian powder was macerated with 70% ethanol. The young leaves of durian extract was analyzed the phytochemistry screening. Then young leaves of durian extract was tested antioxidant activity to DPPH radical by measuring absorbance by spectrophotometer, then it was calculated the percentage of reduction and IC50 value. Rutin was used as a positive control. This research result showed that ethanolic extract of young leaves of durian had antioxidant activity with a value IC50 of 177,37 ppm. The young leaves of durian ethanolic extract contained phenolic compound, tannin, flavonoid, and saponin. Keywords: The young leaves of durian (Durio zibethinus L.), antioxidant, DPPH
