Abstract

Fifteen compounds, which included six chiral lignans and nine phenolic glycosides, were separated from the butanol fraction of Averrhoa carambola L. root and identified. All of the compounds, namely 3,4,5-trimethoxyphenol-1-O-β-D-glucopyranoside (1), benzyl-1-O-β-D-glucopyranoside (2), (+)-5'-methoxyisolariciresinol 3α-O-β-D-gluco-pyranoside (3), (+)-isolariciresinol 3α-O-β-D-glucopyranoside (4), koaburaside (5), (+)-lyoniresinol 3α-O-β-D-glucopyranoside (6), (−)-lyoniresinol 3α-O-β-D-glucopyranoside (7), (−)-5'-methoxyisolariciresinol 3α-O-β-D-glucopyranoside (8), (−)-isolariciresinol 3α-O-β-D-glucopyranoside (9), 3,5-dimethoxy-4-hydroxyphenyl 1-O-β-apiofuranosyl (1''→6')-O-β-D-glucopyranoside (10), 3,4,5-trimethoxyphenyl 1-O-β-apiofuranosyl (1''→6')-β-gluco-pyranoside (11), methoxyhydroquinone-4-β-D-glucopyranoside (12), (2S)-2-O-β-D-gluco-pyranosyl-2-hydroxyphenylacetic acid (13), 3-hydroxy-4-methoxyphenol 1-O-D-apio-furanosyl-(1''→6')-O-β-D-glucopyranoside (14) and 4-hydroxy-3-methoxyphenol 1-O-D-apiofuranosyl-(1''→6')-O-β-D-glucopyranoside (15) were isolated from this plant for the first time.
