The seed and the peel of <em>P.edulis</em> always removed and do not have economical values. The aim of the study was to determine the antioxidant activity of the seed and peel of <em>P.edulis</em> and its potential as an elastase inhibitor. The seed and the peel were extracted using ethanol 70%. The extracts were evaporated and the antioxidant activity was determined using H<sub>2</sub>O<sub>2</sub> scavenging method. The IC<sub>50</sub> values of H<sub>2</sub>O<sub>2</sub> scavenging activity of peel and seed extract were 626.31 ± 2.10 µg/mL and 2106.46 ±33.21 µg/mL respectively. the effect of variation concentration of seed and peel extract showed that the antioxidant activity was dose-dependent manner. The IC<sub>50</sub> value of elastase inhibitor of peel and seed extract was 62.82 ± 1.50 µg/mL and 41.06 ± 0.31 µg/mL respectively. This result gave the promising effect of peel and seed extract of<em> P.edulis</em> as an anti-aging cosmetic ingredient.</p>}, number={1}, journal={American Scientific Research Journal for Engineering, Technology, and Sciences}, author={Vera, Krusty and Raif, Ahmad and Ikhtiari, Refi}, year={2019}, month={Feb.}, pages={43–48} }
