underreported, while other species such as P. petiolosa and P. lancelota have been
reported as sources of antioxidants. Antioxidants have an important role in maintaining
health because they can capture free radical molecules which are the causes of various
diseases. This study aims to determine the antioxidant activity of extract of P. longifolia.
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.
