Two new phenolic glycosides,7S,8R-urolignoside-9\'-O-β-D-glucoside (1) and scrophenoside G (2),were isolated and identified from the seeds of Ginkgo biloba L.,a famous traditional medicine and functional food around the world.Their structures were elucidated by spectroscopic methods (1D and 2D NMR,HR-ESI-MS,and CD),and the comparisons of spectroscopic data with the reported values in the literature.
