    Natural products such as herbs, fruits, spices, beverages, vegetables are becoming more popular among scientific community and consumers because of their potential to arrest the effect of free radicals in human system. This study investigated the total antioxidant capacity of Curcuma longa and Curcuma xanthorrhiza use as spices and medicinal compound in Southeast Asia. Methanol was used as the extraction solvent, 2,2 – diphenyl -1- picrylhydrazil (DPPH) for free radical scavenging activity and ferric reducing antioxidant power (FRAP) assays. Phenolic acid and polyphenol content were both measured. Different concentrations of methanol were used for the extraction to determine flavonoid content and ascorbic acid was used as the control. The results revealed that C. longa had a higher values in all the assays including DPPH (270.1 mg TE/g dw), FRAP (231.7 mg TE/g dw), phenolic acid.. View More»
