The present study aimed to investigate the phenol content and antioxidant activity of a non-conventional Curcuma sp. namely, Curcuma caesia in comparison with another species, Curcuma amada. The total phenol contents of the methanolic rhizome extracts of C. amada and C. caesia were 37.64 and 44.33 mg Tannic acid equivalents (TAE)/g dry material, respectively. The reducing power, and superoxide, ABTS and DPPH radical scavenging activities of C. caesia were higher than
C. amada. These results supported that the non-conventional C. caesia could be an economically important plant species due to its antioxidant potential.
