Megastigmane Glycosides From Phoebe tavoyana

Two new megastigmane glycosides, phoebenoside A (1) and phoebenoside B (2) and 4 known compounds, dendranthemoside A (3), lyoniresinol (4), (+)-3-O-L-rhamnopyranoside-5-methoxyisolariciresinol (5), and (+)-lyoniresinol 3α-O-β-D-glucopyranoside (6) were isolated from the leaves of Phoebe tavoyana (Meisn.) Hook. Their chemical structures were elucidated by analyses of their spectroscopic data, and comparison with those reported in the literature.
