The present study aims at comparing the Phenolics content, Flavonoids and Antioxidant activity of Curcuma amada and Zingiber officinale. The antioxidant activity and phenolic contents of the leaves as determined by the 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay and the total amounts of phenolics and flavonoids were higher than those of the rhizomes. Zingiber officinale had higher antioxidant activities as well as total contents of phenolic and flavonoid in comparison with Curcuma amada.
