<http://eprints.unpak.ac.id/id/eprint/8894> <http://purl.org/ontology/bibo/abstract> "ANALYSIS DETERMINATION OF TOTAL PHENOLIC CONTENT AND\r\nANTIOXIDANT ACTIVITY OF PUCUK MERAH (Syzygium myrtifolium Walp.) BASED\r\nON SOLVENT TYPE AND EXTRACTION METHOD\r\nRizky Mulyana Syarif1*, Novi Fajar Utami2 dan Trirakhma Sofihidayati3\r\nProgram Studi Farmasi, Fakultas MIPA, Universitas Pakuan, Bogor, Indonesia\r\nABSTRACT\r\nPucuk merah are known as ornamental plants for home and garden decoration. Its main use as an ornamental plant\r\noutweighs its use as a potential medicine. Red shoots have been shown to contain various secondary metabolite\r\ncompounds, one of which is phenolic compounds and has antioxidant potential. This study aims to determine the\r\nlevels of phenolic compounds, the best type of solvent and antioxidant activity in red shoots leaf extract based on the\r\ntype of solvent and extraction method. Phenolic levels and antioxidant activity were determined using a UV-Vis\r\nSpectrophotometer. The results of this study indicate that the total phenolic content in the pucuk merah leaf extract\r\nusing the UAE method in 96% ethanol solvent, ethyl acetate and n-Hexane obtained were 17.6381, 10.1349, and\r\n0.9219%, while the reflux method obtained 16.6246, 8.3334, and 0.8305%. Then the antioxidant activity in the UAE\r\nmethod in 96% ethanol solvent, ethyl acetate and n-Hexane obtained IC50 values of 16.0259, 66.9439, and 152.6841\r\nppm, while the reflux method obtained 24.7693, 76.1721, and 162.6266 ppm. The total phenolic content and\r\nantioxidant activity of pucuk merah leaf extract using 96% ethanol solvent with the UAE method were the highest,\r\nnamely 17.6381% and IC50 16.0261 ppm.\r\nABSTRAK\r\nPenentuan Kadar Fenolik Total dan Aktivitas Antioksidan Daun Pucuk Merah (Syzygium\r\nmyrtifolium Walp.) Berdasarkan Jenis Pelarut dan Metode Ekstraksi\r\nTanaman pucuk merah dikenal sebagai tanaman hias untuk dekorasi rumah dan taman. Pemanfaatan utamanya sebagai\r\ntanaman hias mengungguli penggunaannya sebagai potensi obat. Daun pucuk merah telah terbukti mengandung\r\nberagam senyawa metabolit sekunder, salah satunya yaitu senyawa fenolik dan berpotensi antioksidan. Penelitian ini\r\nbertujuan untuk menentukan kadar senyawa fenolik, jenis pelarut terbaik serta aktivitas antioksidan pada ekstrak daun\r\npucuk merah berdasarkan jenis pelarut dan metode ekstraksi. Kadar fenolik dan aktivitas antioksidan ditentukan\r\ndengan alat Spektrofotometer UV-Vis. Hasil penelitian ini menunjukkan bahwa kadar fenolik total pada ekstrak daun\r\npucuk merah menggunakan metode UAE pada pelarut etanol 96%, etil asetat dan n-Heksan diperoleh yaitu 17,6381,\r\n10,1349, dan 0,9219%,sedangkan pada metode refluks didapatkan 16,6246, 8,3334, dan 0,8305%. Kemudian aktivitas\r\nantioksidan pada metode UAE pada pelarut etanol 96%, etil asetat dan n-Heksan mendapatkan nilai IC50 sebesar\r\n16,0259, 66,9439, dan 152,6841 ppm, sedangkan metode refluks diperoleh 24,7693, 76,1721, dan 162,6266 ppm.\r\nKadar fenolik total dan aktivitas antioksidan pada ekstrak daun pucuk merah menggunakan pelarut etanol 96% dengan\r\nmetode UAE paling tinggi yaitu 17,6381% dan IC50 16,0261 ppm.\r\nKata kunci: Pucuk Merah, Variasi Pelarut, Perbedaan Metode, Kadar Fenolik, Antioksidan."^^<http://www.w3.org/2001/XMLSchema#string> .
