- The of research antioxidant activity of tuber extract of bawang tiwai was carried out in the water solvent on 100°C combined with ethanol solvent 96%.The parameter of antioxidant activaty with had been analyzed was:total of fenol. total of antioxidant activity, capacity of free radical capture, reduction power, oxygen reactive species.The result of this research was that the total of fenol resulted in ethanol solven was higher than water solvent, the antioxidant activity of 100 ppm bawang tiwai extract in ethanol solvent is better than in water solvent,but still lower than vitamin C,the capacity of free radical capture combined with ethanol solvent50 ppm was higher than water solvent50ppm.butstilllowerthanvitamin C.Reduction power of tuber extract of bawang tiwai combined with ethanol solvent was hight than water solvent 50 ppm, but stil lower than vitamin C and reactive oxygen with ethanol species of tuber extract of bawang tiwai combined with ethanol solvent was better than water, but still lower than vitamin C.
