This study aims to determine the activity of antioxidant compounds from Dayak bulb ethanol extracts from Kotamobagu City. This research method is an experimental laboratory. Initially the Dayak bulb sample was extracted maceration with 96% ethanol solvent then evaporated until a thick extract was obtained. As a parameter, the DPPH method (1,1-diphenyl-2-picrylhydrazyl) was used to test the antioxidant activity of the samples at concentrations of 50, 60, 70, 80 and 90 mg / L and as a comparison standard used Vitamin C with concentrations of 2, 4, 6, 8 and 10 mg / L. The results obtained showed antioxidant activity in Dayak bulb ethanol extracts with IC50 values of 41.46 mg / L and on vitamin C IC50 values of 1.04 mg / L. Based on these results it can be concluded that the onion bulb ethanol extract has very strong antioxidant activity.
