Abstract
The stem barks of Mallotus leucodermis Hook F.
(Euphorbiaceae) was studied for its chemical constituents. The air dried and pulverized of stem bark of M.
leucodermis (1.3 kg) was extracted successively with acetone for three days
at room temperature yielding 66.0 g of crude extract. The crude extract was fractionated
using vacuum liquid chromatography (VLC) to afford six fractions. Fraction 6
was further washed and recrystallized to afford bergenin (1). Fraction 3 was
subjected to multiple purification using radial chromatography (CHCl3:
acetone) with different ratio 9:1, 8:2, 6:4 and 5:5 to yield a flavonoid
compound, epicatechin (2). These compounds were elucidated based on
spectroscopic analysis (Ultra Violate, Infra-Red, Mass Spectrometry and Nuclear
Magnetic Resonance) as well as comparison with literatures.

Abstrak
Kulit ranting Mallotus leucodermis Hook F. (Euphorbicaeae)
telah dikaji untuk sebatian kimianya. Kulit ranting M. leucodermis (1.3 kg)
yang telah dikeringkan dan dikisar, direndamkan dalam aseton selama tiga hari
pada suhu bilik bagi memperolehi 66.0 g bahan ekstrak. Fraksinasi telah
dilakukan ke atas ekstrak tersebut dgn menggunakan hampagas kromatografi cecair
dan menghasilkan enam fraksi. Fraksi 6 telah dicuci beberapa kali dan
dihablurkan semula untuk menghasilkan bergenin (1). Manakala fraksi 3 ditulenkan
beberapa kali menggunakan radial kromatografi untuk mendapatkan sebatian
flavonoid, epicatechin (2). Dua sebatian tulen ini dikenal pasti berdasarkan
analisis spektroskopi (Ultralembayung, Inframerah, Spektrometri Jisim and
Resonans Magnet Nukleus) dan juga perbandingan data.
