【 摘 要 】

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 -β-D-apio-furanosyl-(1''→6')-O - β-D-glucopyranoside (14) and 4-hydroxy-3-methoxyphenol 1-O -β-D-apiofuranosyl-(1''→6')-O - β-D-glucopyranoside (15) were isolated from this plant for the first time.
