摘要

A disaccharide compound, p-methoxyphenyl 2,3,4-tri-O-benzyl-β-L-arabinopyranosyl-(1→6)-2-O-benzyl-3,4-di-O-acetyl-β-D-galactopyranoside (17), was successfully synthesized from two monosaccharides L-arabinose and D-galactose and fully characterized. This compound can be used to build a natural product 4"-O-acetylmanan thoside B, which was isolated from the leaves and stems of a kind of Vietnamese Acanthaceae Justicia patentiflora.
