Abstract

Garcinia tetranda Pierre adalah salah satu tumbuhan family Clusiaceae yang memiliki kandungan senyawa fenolat seperti santon. Senyawa turunan santon diisolasi menggunakan metode kromatografi kolom gravitasi (KKG), kromatografi lapis tipis (KLT), dan pemurnian menggunakan metode rekristalisasi. Penentuan struktur senyawa menggunakan analisa data spektrum UV, IR, 1H-NMR dan13C-NMR. Senyawa turunan santon yang berhasil diisolasi dari kayu batang Garciniatetranda Pierre adalah 1,3,4,6-tetrahidroksi-5-metoksisanton (124,5 mg) berupa padatan berwarna kuning dengan titik leleh 208-210 °C ============================================================ Garcinia tetranda Pierre is one of the family Clusiaceae which contain fenolat compound like xanthone. Derivative xanthone was isolated by gravitation column chromatography, thin liquid chromatography and was purified by recrystallization. The structure was elucidated by analyze of spectroscopy data UV, IR, 1H-NMR dan13C-NMR. A new compound of derivative xanthone was successfully isolated from stem wood of Garcinia tetranda Pierre is 1,3,4,6-tetrahydroxy- 5-methoxyxanthones (124.5 mg) was obtained in yellow powder with melting point 208 – 210 °C.
