ABSTRAK Uji aktivitas antioksidan daun Murraya koenigii terhadap radikal bebas DPPH dilakukan dengan metode DPPH (1,1-Diphenyl-2-pycrilhydrazil). Ekstrak etil asetat memiliki aktivitas antioksidan paling kuat dibandingkan dengan ekstrak metanol dan n-heksana secara berturut-turut berdasarkan nilai IC50 yaitu 23; 50,54; dan 64,70 ppm. Dari kromatografi kolom (KK) diperoleh 8 (A-H) sub-fraksi. Sub-fraksi G menunjukan aktifitas antioksidan yang paling kuat mendekati IC50 vitamin C (3,75 ppm) adalah 14,41 ppm. Kata kunci: Murraya koenigii, DPPH (1,1-diphenyl-2-pycrilhydrazil), Antioksidan. ABSTRACT Antioxidant activity test of Murraya koenigii leaves against free radical of DPPH by DPPH (1,1-Diphenyl-2-pycrilhydrazil) method. Ethyl acetate extract has the strongest antioxidant activity compared with the methanol and n-hexane extract based on IC50 values of 23; 50,54; and 64,70 ppm, respectively. Column chromatography (KK) obtained 8 (A-H) sub-fractions. The sub-fraction G shows the strongest antioxidant activity near to value IC50 vitamin C (3,75 ppm) was 14,41 ppm. Keywords: Murraya koenigii, DPPH (1,1-diphenyl-2-pycrilhydrazil), Antioxidant.
