Abstract This study aimed to test the antioxidant activity of ethanol extract of curry leaves (Murraya koenigii (L.) Spreng) using the 2,2-Diphenyl-1-picryhidrazyl (DPPH) method. This study was conducted experimentally with maceration extraction, and followed by testing using UV-Vis spectrophotometry to determine the IC50 value. The study of the study showed the strong antioxidant potential of the curry leaf extract. This research used experimental methods conducted in the laboratory. Curry leaf samples were extracted using 96% ethanol, then an antioxidant test was carried out. The antioxidant activity test was carried out using the DPPH method and analyzed using UV-VIS spectrophotometry to determine the IC50 value of curry leaf ethanol extract and Vitamin C was used as a comparator. The study of the study showed that curry leaf ethanol extract has strong antioxidant activity. The IC50 value obtained is above 50μg/ml, indicating its ability to ward off free radicals. This activity was confirmed through DPPH tests and analysis using UV-Vis spectrophotometry. The conclusion of this study showed that curry leaf ethanol extract has strong antioxidant activity with an IC50 value of 59.54 μg/ml and for Vitamin C as a comparator, the result is 9.70 μg/ml. Based on the research that has been conducted, it is necessary to conduct further research using other antioxidant test methods, to measure the activity of curry leaves (Murraya Koenigii (L.) Spreng). Further research can also be developed using other parts of the plant such as flowers, stems, and fruits. 1
