Abstract

Breadfruit leaves (Artocarpus altilis) contains saponins, polyphenols, tannins and flavonoids. Polyphenols and flavonoids act as antioxidants. This study aims to determine the antioxidant activity of ethanolic extract, fractions of n-hexane, ethyl acetate fraction, water fraction of ethanol extract of breadfruit leaves to DPPH radicals with IC50 parameters. Breadfruit leaves powder was macerated with 70% ethanol. The ethanol extract was further fractionated with n-hexane, ethyl acetate and water. Extract and the fractions of breadfruit leaves were tested antioxidant activity to DPPH radical then it were calculated percent reduction and IC50 value. Rutin was used as a positive control. The results showed that the antioxidant activity of n-hexane, ethyl acetate, water fractions and ethanol extracts had IC50 value of 98,42 ± 0,86 ppm; 18,57 ± 0,14 ppm; 42,43 ± 0,37 ppm; 53,27 ± 0,04 ppm. Ethyl acetate fraction of breadfruit leaves has the highest antioxidant activity. Keywords: Breadfruit leaves (Artocarpus altilis), Antioxidant, DPPH.
