UJI AKTIVITAS ANTIOKSIDAN EKSTRAK ETIL ASETAT KULIT BATANG GALINGGANG DIPHENYL-2 PYCRILHYDRAZIL

ABSTRAKUji aktivitas antioksidan ekstrak kulit batang Cassia alata dilakukanmenggunakan 1,1-Diphenyl-2-pycrilhydrazil 37,03 ppm. Uji fitokimia pada ekstrak etilasetat kulit batang Cassia alata mengandung senyawa golongan flavonoid,steroid, kumarin, fenol dan juga kuinon. Ekstrak kasar etil asetat sebanyak 7 gdilakukan pemisahan menggunakan Kromatografi Kolom 6050dan 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, 24,36ppm, dan 41,98 ppm.50Kata kunci: Galinggang ABSTRACTThe antioxidant activity test of Cassia alata bark extract was performed using 1,1Diphenyl-2-pycrilhydrazilvalue of 37,03 ppm. Phytochemical test on ethyl acetate bark extract ofCassia alata contained flavonoid, steroid, coumarin, phenol and quinonecompounds. 7 g of ethyl acetate extract was carried out by using ColoumnCromarography G50silica sationary gel phase and eluen n-hexane: ethyl acetate5060value 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.Key words: Galinggan
