Pumpkin seeds, generally discarded as trash, have been found to be rich in bioactive compounds. Therefore, the present work was carried out to study the potential use of pumpkin seeds as a bioactive ingredient for radical scavenging activity. Processed aqueous and ethanolic extracts of white pumpkin seeds (WPS) and orange pumpkin seeds (OPS) were selected to assess the total antioxidant activity, DPPH and H2 O2 radical scavenging activities. OPA (aqueous orange pumpkin extract) demonstrated highest inhibition for DPPH. Further, WPA (aqueous white pumpkin extract) showed highest inhibition for H2 O2 scavenging activities. The results, therefore indicated that the pumpkin seeds may contribute to radical scavenging activity
