Invitro-Antioxidant activity of the seed and leaf extracts of syzygium cumini

Abstract

The present research was subjected to screen invitro antioxidant activity of the seed and leaf extract of Syzygium cumini. The antioxidant activity was determined by in vitro methods such as 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging assay, ABTS Assay, Total antioxidant activity (Phosphomolybdic acid method), Nitric oxide radical scavenging, Ferric reducing antioxidant power (FRAP) assay, Hydroxyl radical scavenging activity, Total Reducing antioxidant potential, Reducing power. The extract showed significant antioxidant activity in all antioxidant assays when compared to ascorbic acid. The results of this research work are promising thus indicating the utilisation of the seed and leaf of Syzygium cumini as a significant source of natural antioxidants
