| Abstract: | Five new tetranortriterpenoids, toonaciliatones B–F ( 1 – 5 , resp.), together with four known compounds, dihydrocedrelone ( 6 ), cedrelone ( 7 ), 6α‐acetoxyazadirone ( 8 ), and 6α‐acetoxy‐14β,15β‐epoxyazadirone ( 9 ), were isolated from the seeds of Toona ciliata. Their structures were elucidated by spectroscopic methods, including 1D‐ and 2D‐NMR spectroscopy. |
