Abstract

Penelitian ini melanjutkan penelitian terdahulu tentang spesies Garcinia tetrandra Pierre yang termasuk dalam genus Garcinia dan keluarga besar Cluciaceae yang mengandung turunan senyawa santon terprenilasi, didapatkan dari Koleksi Taman Nasional Meru Betiri, Jember, Jawa Timur. Senyawa 1 yang merupakan mangostanasanton I (1) telah berhasil diisolasi dari ekstrak diklorometana kulit batang G. tetrandra Pierre menggunakan metode ekstraksi secara maserasi yang dielusi dengan berbagai pelarut dengan menaikkan kepolarannya, fraksinasi menggunakan berbagai metode kromatografi (kromatografi cair vakum dan kromatografi kolom grafitasi), dan pemurnian menggunakan rekristalisasi dua pelarut. Penentuan struktur senyawa didasarkan pada analisa spektroskopi IR, UV, 1H-NMR, dan 13C-NMR. ========================================================= Digeranylated xanthone which has similarity with mangostanaxhantones I (1) was isolated from the stem bark of Garcinia tetrandra which continues the previous research and can be found in Meru Betiri National Park Collection, Jember, East Java. The dichloromethane extract from the stem bark of G. tetrandra was obtained by maseration method eluted with gradient of various solvents by increasing the polarity, fractionation using various chromatographic methods (vacuum liquid chromatography and column gravity chromatography), and was purificated by recrystallizationThis structure was elucidated on the basis of IR, UV, 1H-NMR and 13C-NMR spectroscopic data in addition to comparison with literature data
