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