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.
