Abstract

Phytochemical investigation has been carried out on the stem bark of Shorea bracteolate . Three known oligomeric stilbene compounds, namely vaticanol A (1), stepnophyllol C (2) and hopeaphenol A (3) were isolated from the acetone extract of the plant. The structure of the isolated compounds were determined based on the analysis of spectroscopic data, including Nucleus Magnetic Resonance (NMR), Ultra Violet (UV), Infrared (IR) and comparison with literature.

 

Keywords:  ε-viniferin, hopeaphenol, Vaticanol A, Stepnophyllol C, Shorea bracteolate, dipterocarpaceae

 

Abstrak

Kajian fitokimia telah dilakukan ke atas bahagian kulit batang Shorea bracteolate.  Tiga sebatian oligomerik stilbene iaitu  vatikanol A (1), stepnofilol C (2) dan hopeafenol A (3) telah diasingkan daripada ekstrak aseton S. bracteolate. Struktur sebatian-sebatian ini telah ditentukan menggunakan analisis data spektroskopi termasuk Resonans Magnet Nukleus (NMR), Ultra Violet (UV), Infra merah (IR), dan perbandingan dengan literatur.

 

Kata kunci:  ε-viniferin, hopeaphenol, Vaticanol A,  Stepnofilol C, Shorea bracteolate, dipterocarpacea
