Abstract

Five new biflavonoids, 1–5, were isolated from the stem bark of Daphne aurantiaca. The structures were elucidated as 2,2″‐bisteppogenin (1), 2,2″‐bisteppogenin 7‐O‐β‐glucopyranoside (2), 2′′′‐dehydroxy‐2,2″‐bisteppogenin (3), 2′′′‐dehydroxy‐2,2″‐bisteppogenin 7‐O‐β‐glucopyranoside (4), and 7‐methoxyneochamaejasmin B (5) on the basis of spectral analyses.
