This study aims to determine the antioxidant activity of the ethanol extract, hexane fraction, ethyl acetate fraction and water fraction of cardamom leaves (Elettaria cardamomum (L.) Maton). Dried of cardamom leaves was extracted by maceration using 70 % ethanol, then followed by fractionation based on the level of polarity with hexane, ethyl acetate, and water solvents. Antioxidant activity examination was determined using reagent DPPH using UV-Visible spectrophotometry and gallic acid as standard. The results of phytochemical screening showed that ethanol extract and water fraction of cardamom leaves contains phenol, flavonoids, tannins, and saponins, for ethyl acetate fraction contains phenol, flavonoids, and tannins, for hexane fraction the results were negative for all the compounds tested. The results of the antioxidant activity examination of ethanolic extract, hexane fraction, ethyl acetate fraction and water fraction of cardamom leaves showed the IC50 of 4058.7 μg/mL, 8419.3 μg/mL, 2281.7 μg/mL, and 3889.6 μg/mL respectively, whereas gallic acid showed the IC50 value of 4.89 μg/mL. Based on IC50 values ethanol extract, hexane fraction, ethyl acetate fraction and water fraction of cardamom leaves have weak antioxidant activity compared to gallic acid which has high antioxidant activity.
