Abstract

Spesies Garcinia tetrandra Pierre adalah salah satu spesies dari keluarga besarCluciaceae yang telah dikenal mengandung turunan senyawa santon terprenilasi. Dua senyawa turunan santon berhasil didapatkan dari ekstrak diklorometana kulit batang Garcinia tetrandra yaitu rubrasanton (1) dan parvifolisanton C (2). Isolasi dua senyawa tersebut menggunakan metode ekstraksi secara maserasi, fraksinasi menggunakan berbagai metode kromatografi (kromatografi cair vakum dan kromatografi radial) dan pemurnian menggunakan rekristalisasi dua pelarut. Penentuan struktur senyawa tersebut berdasarkan analisis spektroskopi IR, UV, 1H-NMR dan 13C-NMR. ============================================================================================ The species of Garcinia tetrandra Pierre is one of the species of the Cluciaceae family which has been known containing derivatives of prenylated xanthone compounds. Two derivatives of xanthone were obtained from dichloromethane extract of Garcinia tetrandrawood bark namely rubraxanthone (1) and parvifolixanthone C (2). Isolation of the two compounds using the method of maceration extraction, fractionation using various methods of chromatography (liquid chromatography vacuum and radial chromatography) and purification by recrystallizing two solvents. Determination of the structure of the compound is based on spectroscopic analysis of IR, UV, 1H-NMR and 13C-NMR.
