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.
