ABSTRAK Uji aktivitas antioksidan ekstrak kulit batang Cassia alata dilakukan menggunakan 1,1-Diphenyl-2-pycrilhydrazil 37,03 ppm. Uji fitokimia pada ekstrak etil asetat kulit batang Cassia alata mengandung senyawa golongan flavonoid, steroid, kumarin, fenol dan juga kuinon. Ekstrak kasar etil asetat sebanyak 7 g dilakukan pemisahan menggunakan Kromatografi Kolom 60 50 dan eluen n-heksana : etil asetat berturut-turut ialah 166,08 ppm, 33,78 ppm, 55,39 ppm, 134,36 ppm, 48,70 ppm, 28,21 ppm, 29,63 ppm, 24,36 ppm, dan 41,98 ppm. 50 Kata kunci: Galinggang ABSTRACT The antioxidant activity test of Cassia alata bark extract was performed using 1,1Diphenyl-2-pycrilhydrazil value of 37,03 ppm. Phytochemical test on ethyl acetate bark extract of Cassia alata contained flavonoid, steroid, coumarin, phenol and quinone compounds. 7 g of ethyl acetate extract was carried out by using Coloumn Cromarography G 50 silica sationary gel phase and eluen n-hexane: ethyl acetate 50 60 value was 166,08 ppm, 33,78 ppm, 55,39 ppm, 134,36 ppm, 48,70 ppm, 28,21 ppm, 29,63 ppm, 24.36 ppm, and 41.98 ppm.
