Analysis the results antioxidant activity test on n-hexane extract had IC50 782,68 μg/mL, dichloromethane had IC50 81,49 μg/mL, ethyl acetate had IC50 28,22 μg/mL and water had IC50 90,22 μg/mL. It was concluded that the extract of n-hexane showed very weak antioxidant activity and dichloromethane, ethyl acetate and water showed strong antioxidant activity.
