Abstract

Separation of methanol extracts of the fruits and stem bark of Styrax benzoin using various chromatography (vacuum liquid chromatography, column chromatography and preparative thin layer chromatography) gave four benzofuran glycosides namely egonol gentiobioside (1), egonol gentiotrioside (2), egonol glucoside (3) and masutakeside (4). The compounds were identified by spectroscopic analysis (NMR, mass and infra-red spectral data) and by comparison of the data with that of the literature. Isolation of compounds from this plant has never been reported before.

 

Keywords: styrax benzoin, styracaceae, egonol gentiobioside, egonol gentiotrioside, egonol glucoside, masutakeside

 

Abstrak

Pemisahan kromatografi ke atas ekstrak metanol buah dan kulit batang Styrax benzoin menggunakan pelbagai teknik kromatografi (kromatografi cecair vakum, kromatografi turus dan kromatografi lapisan thin preparatif) memberikan empat benzofuran glikosida yang bernama egonol gentiobiosida (1), egonol gentiotriosida (2), egonol glukosida (3) dan masutakesida (4). Sebatian ini telah dikenal pasti dengan analisis spektroskopi (data spektrum RMN, jisim dan infra merah) dan membandingkan data ini dengan data kepustakaan. Pemisahan sebatian daripada tumbuhan ini belum pernah dilaporkan sebelum ini

 

Kata kunci: styrax benzoin, styracaceae, egonol gentiobiosida, egonol gentiotriosida, egonol glukosida, masutakesida
