Abstract

Isolation compound and biological activity have been done on stem bark of Vatica
odorata which collected at Mata Kail, Hutan Belum, Perak and Vatica bella from Jengka,
Pahang. All samples were extracted with acetone and methanol at room temperature to give
VOKM (methanol extract of Vatica odorata); VOKA(acetone extract of Vatica odorata);
VBKM(methanol extract of Vatica Bella) and VBKA(acetone extract of Vatica Bella). The
extracts were further subjected to purification by using several chromatographic techniques
such as thin layer chromatography, vacuum liquid chromatography and radial thin layer
chromatography. Two known compounds namely (-)-a-viniferin and (+)-vaticanol B were
isolated from this two plant samples, while a known compound namely e-viniferin were
isolated from V bella and (-)-hopeafenol were isolated from V odorata. All isolated
compounds were elucidated by using their physical properties (physical form, melting point,
optical rotation) and several spectroscopic methods such as infrared spectrophotometry (IR),
ultraviolet-visible (UV-VTS), mass spectroscopy (MS) and nuclear magnetic resonance
spectroscopy (NMR) and also by comparison with the literature data…
