- W2904656785 abstract "ABSTRACTTakokak (Solanum torvum Swartz) is a plant that used as anti-hypertension and appetite enhancer, bloodcirculation, antitussive, and anti-inflammatory. The phytochemical content of takokak leaves are saponins,alkaloids, tannins, flavonoids, and vitamin A which are know as antioxidant. The ethanol extract, and water,n-hexane, ethyl acetate fraction of the leaves of takokak (Solanum torvum Swartz) was tested their antioxidantactivity by DPPH (1,1-diphenyl-2-picrylhydrazyl) method in vitro using UV spectrophotometry visible. Leaves ofTakokak (Solanum torvum Swartz) was extracted by maceration using solvents ethanol and than fractionated byliquid-liquid extraction using water, n-hexane, and ethyl acetate. The results showed that the antioxidant activity of the ethanol extract of takokak leaves (Solanum torvum Swartz), water fraction, the fraction of n-hexane andethyl acetate had EC50 as follows 11 μg/ml, 196 μg /ml; 29.557 μg/ml; 46.67 μg/ml; 7.710 μg/ml. The resultsshowed that the ethyl acetate fraction of takokak leaf had the strongest antioxidant activity with the EC50 valueof 7.710 mg/ml. ABSTRAKTakokak (Solanum torvum Swartz) merupakan tanaman yang berkhasiat sebagai obat penurun tekanan darahtinggi dan penambah nafsu makan, melancarkan sirkulasi darah, mengatasi batuk (antitusif), dan anti radang.Kandungan yang terdapat pada daun takokak adalah saponin, alkaloid, tanin, flavonoid, dan vitamin A yangberkhasiat sebagai antioksidan. Telah dilakukan pengujian aktivitas antioksidan secara in vitro pada ekstraketanol, fraksi air, fraksi n-heksana, fraksi etil asetat daun takokak (Solanum torvum Swartz) dengan metodeperedaman DPPH (1,1-difenil-2-pikrilhidrazil) menggunakan spektrofotometri UV-Visible. Daun takokak(Solanum torvum Swartz) diekstraksi secara maserasi menggunakan pelarut etanol, fraksinasi dengan caraekstraksi cair-cair menggunakan pelarut air, n-heksana, dan etil asetat. Hasil penelitian menunjukkan aktivitasantioksidan ekstrak etanol daun takokak (Solanum torvum Swartz), fraksi air, fraksi n-heksana, fraksi etil asetatmemiliki EC50 berturut-turut 11, 196 μg/ml; 29,557 μg/ml; 46,67 μg/ml; 7,710 μg/ml. Dari hasil penelitianmenunjukkan bahwa fraksi etil asetat daun takokak memiliki daya antioksidan paling kuat yaitu dengan nilaiEC50 7,710 μg/ml.Kata kunci: Solanum torvum Swartz, DPPH, spektrofotometri UV-Visible, ECC, EC50" @default.
