Abstract:

Ten known flavonoid C-glycosides identified as 2′′-O-β-D-glucopyranosyl isovitexin (1), spinosin (2), 6′′′-acetyl spinosin (3), 6′′′-p-hydroxycinnamoyl-2′′O-β-D-glucopyranosyl isovitexin (4), 6′′′-p-hydroxy-cinnamoyl spinosin (5), 6′′′-(E)-feruloyl O-β-D-glucopyranosyl isovitexin (6), isospinosin (7), isovitexin (8), swertisin (9), swertiajaponin (10) were purified from the seeds of Hovenia dulcis Thunb. Their structures were confirmed by spectroscopic data analysis and comparison with previous literature. All compounds were obtained from H. dulcis for the first time.
