Abstract:
Ten glycosidic compounds were isolated from an ethanol extract of Machilus wangchiana by a combination of various chromatographic techniques including column chromatography over silica gel and Sephadex LH-20 and reversed-phase flash chromatography and HPLC. Their structures were identified by spectroscopic data analysis (IR, MS, and NMR) as icariside B1 (1), boscialin-3-O-β-D-glucopyranoside (2), pisumionoside (3), isolariciresinol-9'-O-β-D-xylopyranoside (4), 5'-methoxyisolariciresinol-9'-O-β-D-xylopyranoside (5), lyoniresinol-9'-O-β-D-xylopyranoside (6), (E) -4-hydroxyphenylprop-7-ene 4-O-β-D-glucopyranoside (7), (E) - 4-hydroxy-3-methoxyphenylprop-7-ene 4-O-α-L-rhamnopyranosyl-(1 --> 6) -β-D-glucopyranoside (8), 4-hydroxy-3-methoxyphenylprop-8-ene 4-O-β-D-xylopyraosyl-(1 --> 6) -β-D-glucopyranoside (9), and 4-hydroxy-3,5-dimethoxyphenylprop-8-ene 4-O-α-L-rhamnpyranosyl-(1 --> 6)-β-D- glucopyranoside (10), respectively.
