Temu blenyeh (Curcuma purpurascens Bl) is a species of curcuma that is still rarely studied. Temu blenyeh is thought to have antioxidant activity so that it can reduce free radical activity. The purpose of this study was to screen phytochemicals and to determine the antioxidant activity of temu blenyeh extract using the 2,2-Diphenyl-2-picrylhydrazyl (DPPH) method. Temu blenyeh extract was macerated with 96% ethanol solvent, then its antioxidant activity was tested using the 2,2-Diphenyl-2-picrylhydrazyl (DPPH) method at a maximum wavelength of 515.8 nm and using vitamin C as a comparison. group of flavonoid compounds, alkaloids, tannins, saponins, triterpenoids and steroids. While the results of the antioxidant activity of temu blenyeh extract are in the very weak category with an IC50 of 458,888ppm and vitamin C with an IC50 of 3,294 ppm.
