Hedychium coronarium Koen. (Family Zingiberaceae), popularly named butterfly ginger, is widely available in tropical and subtropical regions.The present study was undertaken to compare the antioxidant activity of hexane, chloroform and methanolic extract of rhizomes between ferric-reducing antioxidant power assay (FRAP) and Diphenyl picrial hydrazyl radical scavenging assay (DPPH). The results showed that, Diphenyl picrial hydrazyl radical scavenging assay (DPPH) has more hexane, chloroform and methanolic concerntrations than FRAP. The objective of the present study was to identify the main constituents of the rhizomes of H. coronarium and to investigate the antioxidant activity.
