Abstract
Senyawa turunan lupeol, yang berupa padatan putih (51 mg)
dengan titik leleh 165-166 °C berhasil diisolasi dari kulit batang
tumbuhan Garcinia balica. Proses pemisahan dilakukan
menggunakan metode Kromatografi Kolom Cair Vakum (KCV).
Pemurnian senyawa dengan metode rekristalisasi dalam Etil
Asetat. Struktur senyawa turunan lupeol, dielusidasi
menggunakan Spektroskopi IR, Spektroskopi 1H-NMR dan 13CNMR

Lupeol derivative, was obtained in white powder with the
melting point 165-166 °C. This compound was isolated from stem
bark of Garcinia balica. The fractination was done by vacum
column chromatography and was purified by recrystallization
with Ethil Acetate. The structure was elucidated by spectroscopy
IR, 1H-NMR and 13C-NMR data
